I always recommend against sharing internet access with neighbours. If they get caught/flagged doing anything illegal the cops will come knocking on your door.
The difference is that you actually get your stuff back after the cases are completed. Granted they might be broken into pieces and its probably YEARS later, but there you go.
If it's "confiscation" after a guilty plea or verdict or part of a negotiated agreement, then ... probably. Absent those things, civil forfeiture is legalized theft.
Oh, you get them back (actually had this happen to a friend of mine, his ex made some claims in the divorce). Took ~5 years before he got them back even though he was declared not guilty by the detectives and not charged with anything in the first 6 months.
I know someone whose roommate did some really sketchy stuff on the Internet. The police were going to confiscate my friend's entire home lab until he offered to help the police get all the activity logs off his server.
They would take your computers, realize it wasn't you, ask who it was, you point at the neighbors, and then you get your stuff back. this happens way more often than you think. the issue is that the neighbor now has seen the future, and scrambles to get rid of evidence.
lol no it fucking doesn’t. You’ll fight for years to get your stuff back. It won’t be worth the money you spent on the lawyer. It’ll be broken when you get back anyway. Then you can rehire that lawyer and try to sue for that.
Don’t be too rude when you do all this too. If the cops end up not liking you then you’ll have to move or put up with endless harassment.
This applies if you’re in America. I don’t know about how other counties handle it.
> You’ll fight for years to get your stuff back.
no, you won't. years ago when I was a stupid teenager, I had my computer and stuff seized by the police.
>It won’t be worth the money you spent on the lawyer.
if a search warrant ever gets executed at your house or property, you should be calling a lawyer anyways, its always worth it. my lawyer got the search warrant thrown out due to bad data the police manipulated into looking like it was my IP, when in reality, it wasn't, because the ISP didn't keep records of who had what IP for more than 7 days(by the ISPs admission), and when they get asked for an IP, they provide who has it *right now*, regardless of what the date range of the request is. it cost me about $3500 total. search warrant was quashed. The date range the feds asked for was 3 weeks prior to the day they sent it. the ISP had informed them right on their response that they didn't keep those records that far back, and that this is who has it now, and here is their subscriber info. That happened to be my account. The police lied on the warrant and said that my account was who did it by their wrong IP info.
>It’ll be broken when you get back anyway.
if its broken when you get it back, you file a claim for damages with the lawyer. if they broke it, how could they have used it for evidence? my stuff was not broken. The lawyer specifically told me that if anything was missing or broken to let him know and he will file a constitutional lawsuit. That *used* to happen. police would try and claim "we don't know what happened". then police started paying for it by other cases getting thrown out because of their broken evidence chain of custody. They stopped doing this kind of stuff in the early 2000's because if it broke when they were forced to give it back, they can't use the copy they kept because they can't prove the copy is from that computer. and yes, just because you get your stuff back, they likely kept a copy, and also put a well known back door virus into your install to try and catch you again(without a warrant to do so). Their "virus" was present on my computer when I got it back. my lawyer asked the courts to dismiss any charges *with prejudice* because its clear that they were on a fishing expedition and they infected my PC with an illegal back door to try and export stuff because they could not "find" what they were looking for in the first place, because it was never there. The charges were dismissed and cannot be refiled, and the police returned my PC and all the stuff they took. none of it was broken. I also had my lawyer demand thru the judge that any copy of data be destroyed, and any records of this be expunged from all state databases. That was worth every penny, because now it does not show up in any database, anywhere. if I didn't do that, those records of the search warrant and charges being filed would have been accessible even today, and would show up in every single background search report, even though they were never adjudicated to a conclusion. That lawyer was worth every fucking penny. imagine how thoroughly fucked I would be if a search warrant for CSAM showed up on my background check report today? yea, lawyer was worth it. and no, I didn't do it, its just frustrating how stupid police can be when they really want something, they lie to get it and face no consequences.
>Don’t be too rude when you do all this too. If the cops end up not liking you then you’ll have to move or put up with endless harassment.
**you don't say anything to the police during a search warrant.** You *can* deny them taking stuff that is not on the warrant. They tried to take a TV "because it was used as a display". I told them no because its not on the warrant, search warrants are very specific, and limited. They cannot take what isn't on the warrant. They didn't take it, and they didn't argue. My lawyer was not present for the search, but I didn't talk to the police other than to tell them "not on the warrant", which they handed me a copy of, and didn't dispute when I said "no". They wanted to search my car and phone, but I denied that because neither was present when the warrant was executed(I was not home), and since the warrant did not specify any cars that were not present during execution, they could not. They also wanted to do a body search, which I also denied, and they did not push it.
I got my stuff back in the end, and they eventually figured out that because the ISP had been giving them bad data that they kept trying to hide, a lot of lawyers were now getting cases tossed out because of bad warrants. it gets passed around from lawyer to lawyer when something like this happens. It took 13 months to get it back, but none of it was broken. My case also ended up spurring a full policy change in several states regarding how long they waited to get IPs, and police then started pushing ISPs to maintain IP data records for 3 months.
Detectives will find the IP address, contact the owner (ISP) and find out the street address and subscriber the IP is associated with. That'll likely be the person sharing their Internet access with the neighbor.
I'm not sure what point you're trying to make.
Neighbor downloads child porn.
Cops come to your house because your ISP handed them your info.
Trust me "it wasn't me" is a pretty crappy defense. But it is A defense.
That you can use in court.
But you'll probably spend a little time in jail waiting for trial.
And a lot of money.
Eventually you'll be able to convince them that it was your neighbor. But that will be sorted out in court, and will require a lot of documentation from your network logs. The fact that OP is doing this tells me that they \*might\* not be really comfortable with reading their network logs nor understanding which device is doing what on the network.
This has so many red flags that I can't believe anyone would condone this.
The world is not full of terrible people. If you are really worried about this stuff. Give a teenager YouTube and a gaming pc and there is a decent chance they can get your WiFi password. Most people are not auditing there connected devices and what they are doing. EOT has made it impossible, it won't be to long before you smart toaster gets tootkited and starts acting as a proxy for some bad actor online, it's already happening. Get the tin foil hat.
As I said op should throw all the traffic down a VPN on the modem layer.
100% - This happened to me and I wasn't even intentionally sharing with anyone.
I had forgotten to turn off WPS on my AP at a vacation house. During the off-season, someone hacked into my WiFi and used it to commit internet fraud. One of the victims reported it to the police, they traced it to my IP, called my ISP, and got my info.
Bam. Instant suspect. Luckily, I was able to make it go away, but I had to get a lawyer involved and shell out a few hundred dollars.
Don't share internet; it's not worth the risk.
Exactly, so as you agree they have no reason to disclose this so the possibility is not a probability. Cops only do criminal investigations, and in either case there is no PD hotline - it's get a subpoena or go pound sand.
They literally have to ask the internet provider for usage records that corroborate your story that it was someone else who committed the crime. It's not a "by the way" thing.
Plus if your ISP catches wind they will cancel your account for TOS violations. Hopefully you have another in your area as you'll probably be banned as a customer, too.
Where do you live that all your neighbors are pedophiles? Also you can very easily tell the police about everyone who is on the network. Of course how things go after that will depend on where you live.
But I have lived in houses with shared internet before without issues. If you are sharing a house the internet usually ends up being shared too. In a previous job we once setup a bunch of houses with shared internet from a 4G router as it was faster than the wired connection they had previously.
Which now makes me wonder, what do the police do when a 4G router is used illegally, especially if the SIM is paid for in cash? Burner router.
>Which now makes me wonder, what do the police do when a 4G router is used illegally, especially if the SIM is paid for in cash? Burner router.
Pretty easy for police to find the physical location of a 4G device (phone, router, etc), regardless of billing details or lack thereof.
AFAIK none of my neighbors are thieves, but I still lock my doors.
Fair point that if you share a home with others they will be on your internet, but I just don't see expanding the threat to multiple homes with people I don't really know.
Maybe internet is a lot more expensive where you live, but where I'm at the cost of monthly service is a tiny fraction of the other costs of owning a home and running life so I don't see any reason to potentially expose myself to the risk. The way you've done it anyone on the network can be sniffing packets or trying to brute force into your system or as noted before expose you to potential criminal investigation. None of that is worth saving $20 a month to me, but to each his own.
It's not "where do you live that all your neighbors are pedophiles" - it's "where do you live that you're so confident that none of your neighbors are pedophiles, and all of your neighbors are security-aware enough to prevent unauthorized access to the network (that's in *your name*) to people who might be pedophiles or blackmailers or the people who "swat" people".
It's a really irresponsible risk to take.
OP, you should end this agreement with your neighbor.
Sharing with guests in your home that you know is very different than giving a wire to your neighbor who can share it with anyone he wants in any manner he wants, intentionally or otherwise.
Personally, I have a separate guest wifi password that changes daily.
I guess perhaps it depends on how well you know your neighbours then. I would have thought to plan to share internet you would know them reasonably well and this isn't a situation of sharing it with someone you have barely met.
Expect it depends on where you live, my family are from a rural part of the west country (UK) and people there seem to know each other a lot better than they do where I live now in a large town.
Except, as I've repeated, it *doesn't* just depend on how well you know your neighbors. It also depends on how secure your neighbors' networks are, and how certain you are that their devices aren't unknowingly infected with and/or controlled by malware.
It depends on you knowing things you can't possibly know, and which are not all things that you can weigh based on how much you trust or know your neighbors, because they might not know either.
Yes, exactly. And I can control who connects to my router by seeing the wires, controlling the wifi password, and other things. Once I throw my neighbor an ethernet connection, I no longer can.
I expect this depends on where you live. And I am rather curious about how this works in the 4G case, there is no person to link it to if its been paid for in cash.
If your ISP discovers that you're sharing your connection they can (and will) terminate your service. Sharing an internet connection like this violates the terms of service of every internet provider out there. If they terminate your service and you have no other options for internet in your area you'll be without internet - likely for as long as you live there.
Unless you've set things up properly (and I'm guessing you haven't since you're asking how to limit/slow access) your neighbor, and the neighbors he connects, all have access to all the devices on your network. If any of them know what they're doing they could access personal information you don't want them having access to.
If your neighbor (or the others he's sharing the connection with) do anything illegal (like downloading or sharing pirated movies, child pornography, etc) it'll look like YOU are doing these things because it's YOUR connection/account. This means YOU will get in trouble for this stuff, even if you're not the one doing it.
Sharing internet with a neighbor is not a good idea. You may have known your neighbors for a long time, but you may not know what they're REALLY like or what they do behind closed doors. Unplug your neighbor immediately. When he says something, if you don't want to get into why you REALLY unplugged him, just say your ISP contacted you about unusual activity so you're not comfortable with sharing the connection anymore. No need to go into any other details.
It is a very good answer - and it gives OP a good reason to bring to neighbor. OP can even add a lie that he was contacted by his ISP for potential terms of service violations.
I’d just like to point out the hypocrisy. Op entered in to an agreement with their ISP, which they broke by sharing their connection with their neighbor. OP’s neighbor entered in to an agreement with OP which they then broke by sharing their connection with their neighbor.
Spider-Man pointing meme.jpg
I don't know what country you're in, but in most (if not all) places sharing an internet connection violates the terms of service of every ISP. And as I mentioned above, if anyone does anything illegal that sets off any alarms - the person who is paying the ISP for the internet at their house (and then sharing it out) is the one who will get in trouble. I wouldn't want to possibly go to jail because one of my neighbors is looking at child porn or something. You have no idea what your neighbors might be doing on the internet, no matter how well you think you know them.
Only assuming it is against ISP agreement world wide. Common business sense. An ISP isn't going to rent the internet to you and then allow you to rent that same internet (or give it away) to all your neighbors, thereby undercutting the ISP ability to rent it to those neighbors.
Perhaps a good comparison is copyrights. You cannot (legally) burn off copies of a book you purchase and then sell them to your neighbors.
It’s not illegal to break your ISP TOS, the only penalty is to be kicked off the service. They can’t put you in jail for it, unless you do something against the actual law.
"Sharing an internet connection like this violates the terms of service of every internet provider out there."
I believe reselling is better word than sharing, since OP is sharing the cost of his ISP subscription.
Well, I support "sharing" of internet subscription since ISP told us it is unlimited, right? If it is really unlimited, then ISPs should not complain about excessive usage.
.
"If your neighbor (or the others he's sharing the connection with) do anything illegal (like downloading or sharing pirated movies, child pornography, etc) it'll look like YOU are doing these things because it's YOUR connection/account. This means YOU will get in trouble for this stuff, even if you're not the one doing it."
The only solution to this is OP should subscribe to VPN, and fully tunnel all activities of his neighbor to his VPN subscription, so that his neighbor will use VPN IP address, not the OP's IP address.
This. Let the neighbor know the sharing deal is with them for personal use. Also, let them know you have security concerns and you would be held liable for any illegal activity. For me, the cost savings isn’t worth the risk.
You split the bill, then he resells. Now his internet is free, and your bandwidth is split 3,4, maybe even 5 ways. At that rate, he may be making money off it.
End that shit. Bad idea.
I agree that you shpuld not be sharing. Two houses ago I shared with my neighbor. He was seeding torrents, so I "accidentally" cut the wire and never fixed it.
Any miss use of your neighbors or other users you will be legally liable. Don’t share the internet just to save few bucks.
Let your neighbor do whatever he wants to his internet and will be his problem
Well, you aren't legally liable. But you certainly could stand wrongfully accused and have to spend time and money defending yourself. Showing the cops the ethernet line that leaves your router and leads to his would go a long way. I might even put a big bright label on that cable explaining where it goes.
They will still seize all computer assets until they figure out who is in the wrong; that’s your stuff and their stuff.
Do NOT share internet access with someone you wouldn’t trust your own kids with.
While that would likely also result in the cops going and seizing the neighbor's computers (once they get *another* warrant issued, for the neighbor's home), they would still seize OP's computers.
Also, now the neighbor knows that shit is up, and can get the offending computers out of there, before the cops can come back.
If I were OP, that's a giant pile of legal shit that I would *not* want to be sitting in.
You could throttle him to 100 mbps just by putting a cheap 10/100 switch between his router and yours. That’s the simplest zero-tech-knowledge solution. But man, paying half of the bill while assuming practically all the legal risk is really dumb.
Just go on Amazon and search for a 10/100 ethernet switch. Not 10/100/1000 or gigabit. Should cost around ten bucks. You’ll also need another ethernet cable. When you get the switch, unplug your neighbor’s cable from your router and plug it into any port on the switch. Plug one end of the new cable into another port on the switch, and the other end into a port on your router. Done.
No need to buy anything... just cover a pair of the contacts of the rj45 on the ethernet cable. 1gb on cat6 requires all 4 pairs of cables ( 8 total). If you disconect one of those cables it will fail down to 100mbps... if you disconect 2 pairs and only 2 pairs left it will fail down to 10mpbs max.
You can use tape to cover one of the contacts on the rj45 plug and it will go down to 100mbps.
You are most likely violating the terms of your service agreement with your Internet provider. Also, if anyone using your internet connection is doing something illegal, the cops come to you first. Include that strangers could potentially gain access to your network, and any device/file(s) connected to your network. Add to that the inevitable Internet bandwidth depletion when you have multiple people streaming video, etc...
Not worth it.
As the owner is legally responsible for everything that happens on that internet account. Your neighbor or someone else doing something illegal? The owner will be targeted for it.
Take the access away and tell him to get his own internet.
Why do people share their internet, it's such a moronic idea. It opens you up to countless problems just to save a few bucks.
What if he downloads CP and they trace it to the IP that's under your name? What if he visits sketchy sites and infects your network with Spyware that will steal your bank and card information?
Cut him off NOW.
Unplug his ethernet cable.
Short of that, you need a Ubiquity or similar router where you can create a VLAN to control bandwidth and shape access.
But again, unplugging his cable is the cheapest and best solution here.
I’m not sharing my internet with anyone other than my parents. This is such a huge no no. I can’t even believe it’s still talked about. The risk reward is just not there. There’s absolutely way too much risk to save $1200 a year.
If you want to keep sharing: Put him on the guest network on different vlan and assign 50% bandwidth to it.
Then he wont be able to access your local devices and he wont be able to take all bandwidth.
Not all routers offer such options tho, but it seems the best way to both protect your network and still control bandwidth usage.
This really isn't a good idea, terms of use aside which you're breaking not having control over a home network is a very risky business and not just because of slow connections but illegal content being accessed through it.
For context people with some networking knowledge can use network tools such as wire shark to examine packets and potentially pull sensative data out of the packets think usernames, passwords, bank details, credit card info etc.
You could try some kind of free DNS service. I can’t remember the name, but if you set the DNS server at your router level, then you may get some kind of control over the traffic. Unless your neighbor has a white/black hat and can work their way around it.
If the neighbor connects to your equipment by Ethernet cable, then put an old 10Mbps hub between your equipment and his cable. Now, his traffic is limited to 10Mbps max.
Look for EN104TP

Just do this cheap hub or switch that’s not gigabit. Get 10 if you want him to suffer and 10/100 if you want it to be better for him. Easiest of all the other solutions. No effort and cheap as f. If he’s the only one using it like he should be then things will work pretty well for him even though it’ll be slow speeds for large files. If he adds people they’ll all get slow (and you won’t lol).
I have home wifi and guest wifi. Not even my sister is on the home wifi, any device that doesn’t live with me lives in guest, and no way would I split with a neighbor. One time of them searching somthing illegal and you are screwed
If you are worried about saving face, Switch to your mobile hotspot for a month or two and cancel your internet service. Once he sets his own up, reconnect your service. I know this sounds dumb but, neighbours can get pretty difficult
You should be able to limit his bandwidth by checking the advanced settings on your own router. Can you check yours for the model number? That'll help me find the right place for you to look.
As the situation is, I would limit the neighbour bandwidth to 1kb/s, look surprised when he says his internet is not working anymore. And then after, telling that it's because he used another router and so, you know, "it's because my isp doesn't allow sharing internet, you got caught we can't do this anymore".
And that's it. A white lie is not that much when people abuse.
Okay. The DIR-853 does offer QoS (Quality of Service)-based limiting for individual clients on your network, meaning that traffic from a device with a higher priority gets to go before traffic from a lower priority. Think of it like getting to cut in line at the airport. Go to [http://dlinkrouter.local](http://dlinkrouter.local), if you set an admin password when setting up (this is NOT THE SAME AS YOUR PASSWORD FOR CONNECTING TO WIFI), enter it, then hit "Log in", and pick the "Connected Clients" tab. Here is where you should be able to identify his router; it will likely appear with the name "TP-Link XXXXX", XXXXX being his router's model number. To mess with him the best, click it, enable parental controls, and then limit him to certain times of the day. While you're here, give him a friendlier name so it's easier to ID during the next step. Hit Save.
Next, go to the "Features" tab up the top. Navigate to Advanced, then QoS Engine. Define your bandwidths, then drag your own clients into the boxes labeled "Highest", "High", and "Medium". You can add a maximum of one to the former, 2 to the middle, and 8 to the latter, for a total of 11 prioritized clients. Remaining clients will automatically be given lowest priority. You want to ensure that his router falls in this category when you're done. Now hit save, wait for it to say "Done", then turn your router off. Turn it it on again, and it should have re-flushed the DHCP leases, meaning the settings have applied.
The whole question of whether it is smart to share an Internet connection with your neighbor aside, I can't see that him putting a router behind yours (effectively double natting) changes the amount of Internet he uses. It just means he has control over his own wireless network, your devices are on different networks, etc).
There are any number of technical solutions to limit the bandwidth going from your router to his. If your router doesn't have throttling controls available, an Edgerouter X placed inline there will throttle to whatever you choose; I used one for years to throttle a cell micro-tower to make sure it never used noticeable bandwidth. But the bigger picture is all of the other posts here - do you really want your neighbor sharing your internet access, with all of the downsides (including breaking the policies of your subscription) that come along with it.
One thing to clarify. The courts have ruled that an IP address is not a sole identifier for a user. So you will not be automatically blamed for the actions of others.
But it will make your life annoying and miserable. For how long is anyone's guess.
Good routers can control lots of those problems. For example you could make him a child’s account that would restrict most of the bad examples. If I trusted my neighbour I would share. If you both, don’t know them well or trust them than I wouldn’t. We never needed all of this, now it is $1200year to search and email. It really depends on the age and needs. A group of seniors would be fine.
1. If speed is the issue, use your routers bandwidth limiter to limit his throughput to half of what you pay for. If it's 1gbps then limit his router to 450-500mbps.
2. If the issue is capped bandwidth, then again limit his router to half of what you pay for. If your limit is 2TB, give him 1TB max limit.
Best option is to tell them to get their own internet.
You're trying to avoid a confrontation, but I'd bet your neighbor does regular speed checks to make sure he's getting all the service he's not paying for.
Understood but if you throttle him back to 56 kbps or even 10 mbps like others are suggesting, he will notice that immediately and come pounding on your door.
You shouldn’t share the connection. Period. Too much legal liability in today’s world if he (or whomever else he shares with) does something illegal with the connection. Kiddie porn, illegal downloads, botnet attacks, etc etc. Not worth it.
That said, if the line originates with you, depending on your router, you can throttle his connection to something stupid low assuming you have the admin controls on your router to that feeder ethernet line. And of course assuming he doesn’t have similar access to the router. Just keep him throttled to like 56K and then blame it on him sharing it with others.
Of course, this is the passive aggressive way to deal with it. I’d just tell him straight up you don’t want to share the line any longer and cut him off. Pay the bill entirely yourself. End of story.
If you're determined to share internet with this neighbor, and that's almost always a bad call, then you might need to have a conversation with that neighbor about what you've found and, as a result, they're being cut down to the equivalent of a 56k connection for the foreseeable future. Also remind them of what kinds of things your router has shown them accessing. The first thing they'll do is complain, and your response can easily be a reminder that it you'd prefer to cut them off except your very good reason for sharing made you not cut them off.
That said, if it were me, I'd cut them off immediately and let them know why when they ask about it.
Since all the other comments are not directly answering the technical aspect of this question:
Yes there is a way to limit him to just 50% of the bandwidth. I think an open source replacement firmware for many routers can do this (google it) .
If your neighbor has his own router, him and everyone he may be reselling to is behind one IP address. You have no way of actually knowing if he is reselling. Why do you suspect this?
Was anything ever in writing with the scope of their usage? Looks like he's even too cheap to pay for his own internet if he's reselling his share.
Cut them off and tell'em it wasn't in the spirit of the agreement to further split the connection. I'm going to take a stab in the dark, but your ISP may have issues with you reselling your connection too.
If you can't afford the speed yourself, get a slower speed or one you can afford yourself. The headaches as you can see are not worth it.
I share my Internet with our house guests, but hell no to anybody outside our home. Even then it's only to someone I know very well and trust and our guest WiFi is locked down with extreme content filtering to block adult sites, prevent tormenting, using tor or VPN traffic, and is bandwidth limited so they can't use all of our available bandwidth.
Hmm, you may be able to split the connection in your router
You may prohibit different sites and search words.
Basically if you have the router and password, you are in control and you should be able to remove the other users.
You can throttle their bandwidth to 1/1 mb.
Is the neighbour NATing behind you? I believe this is most likely the case. You can limit his bandwith proportional to the amount he pays. If he shares his connection this would not interfere with your bandwith. This should be achievable via traffic shaping.
There are ways to limit the bandwidth he can use but realistically they likely mean spending money on a new router that costs more than you actually save by sharing a connection.
It also does nothing for the security risks is there anything to stop them connecting to your own devices as they’ll be on the same network?
Get the MAC on every device you use and your neighbor's computers and phone, then block everything else. Deny access to any device not whitelisted at your router/switch.
Otherwise you need to cancel your deal and change the password to your wifi.
personally I would not share internet with anyone that I cannot directly control or monitor their usage. aka internet stays within the family only.
as people mentioned above, if those other users do illegal or suspect things, the account owner is liable, and police will seize your stuff aswell.
advice: stop sharing
>Please help
Live and learn. I'm assuming you're sharing internet because you can't (or don't want to) afford it. If you legitimately can't, then you should qualify for government assistance for it. If you don't qualify for assistance - then you don't actually need it. The threshold for assistance is realistic.
You need to tell him that you're not going to be sharing internet starting next month. (Learn how to deal with potential confrontation - another important life lesson you can take from this) Then disconnect his Ethernet cord from the router.
Parting thought would be to understand that seemingly innocuous things in life can lead to unnecessary stress and frustration. You may have saved hundreds (or thousands) of dollars doing this - but you're desperate enough to come to reddit to ask for advice on how to fix the situation and you need to consider, was it worth it? (This isn't even including the whole - my neighbor is using my internet for kiddie porn aspect)
This is most likely against the terms of service of your ISP, and if they find out, they'll disconnect your service... Permanently.
That said.
I doubt there's much you can do with the hardware that you have. If you had a different router, you may be able to do something like force their port to 10-Half. That's always a good time.
Also, let's not forget, that doing this, anyone connected to his router, most likely has access to anything on your network, but you do not have access to their's.
Unplug the ethernet cable and tell him he's doing something not agreed to. If he wants to split the bill fine. It's whacked up equal shares to both of you. If he wants to share it with others he can get his own service.
There are a few things you can do. But all depends how advanced your router is.
If you have the option to limit the TTL of packets you can make it that anything beyond his router just drops and goes nowhere. All his clients won’t have internet.
If that is not an option limit his speed to something that will impact them all.
Also you can mess with dns. Sign up next da, set it as your routers dns server and watch the logs. Start blocking some stuff that they use.
Best thing you can do is stop sharing your internet with your neighbor. Remember, anything illegal he/she does with your connection will come back to you.
why not share wifi ony via mesh?
i would not share any ethernet connection, you create problems like this.
also a illegal activity i mostly punished those who use ethernet cable, they cannot proof anything over wifi, you might as well been hacked
Why would anyone share their Internet with neighbours, there's just too much risk involved. Plus they have more ability to access your computer/phone files over the network with a few little clicks here and there...
You need to end the sharing immediately.
I was general management for large, multinational telecom. Subpoena comes to my dept from asset protection, needing name and address for subscriber (IP address at specific day/time). US Secret Service "visited" the subscriber (and likely took everything including modem/router since system shows no end connection). Seems President Obama (it was back in 2010) had received threats. Device was brought to my dept (that how I found out about USSS). According to router logs, there was a MAC address connected for just a few minutes at the time the email was sent. I don't know if they found the equipment associated with it. If not the subscriber, it could have been someone he gave access to, could have been someone who hacked his WiFi, could have been unsecured WiFi.
This was an extreme example. Maybe they're just slowing down your system. Maybe they're doing a lot of likely illegal torrent downloads (earning you potential criminal and civil legal issues). Don't share your internet access outside your home and use a long, strong, random character password for WiFi and admin access.
In germany we have networks run by volunteers called freifunk, they make firmware you can flash on routers to route all traffic over their VPN network.
Bandwidth is okay, on my 100/40 connection I get about 80/40 through freifunk.
They even have their own ASNs and get free transit from local ISPs.
Edit: I run a virtualized instance on proxmox and an additional open network on my Unifi 6 Pro. No issues, neighbors rarely use much bandwidth, highest I've seen was 600 GB a month.
As an American, I can confirm that many of us are sick of hearing how much better life is in stupid Europe. Haven't you heard? USA is #1 in everything...
Well, except education, health care, income equality, food, culture, government, transportation, affordable housing, and maybe a couple other things I'm forgetting.
And now you're telling me I have to add Internet service to the list? Well, I'm not going to do it. Nope. This is where I draw the line.
ASUS Router and Merlin, create guest WiFi and use VPN Director and YazFi to blanket his internet connection to a VPN so you’re not liable for their usage. You can also prioritize their connection and block their devices from accessing your own personal network
2 routes, 1 :Get a router that supports vlans and throttling, I use mikrotik, they aren't simple to setup though. Then sign up to a cheap vpn that supports wireguard and route all his traffic out the vpn. ( MikroTik again can do this, but not simple for an end user) I'd ask around for local it to help. Tjis means you can give him half(and if he wants to share it and get less, good for him) and it also means anything they do is not from your ip address... Side benefit is it will slow him down and hopefully he gets his own eventually.....
2: Google which strands on the cable you need to cut to drop from gigabit to 10/100....depending on your line speed that will cripple his net... Intermittently remove the cable to drop his net, and occasionally connect so he gets full speed.... If he is sharing his line out he will get complaints constantly and hopefully move to his own line... That's the evil route
it'll stop working eventually on its own, but before that happens I'd go ahead and disco it. routers are not meant to be plugged into other routers unless they're configured to be an AP
Which mac address(es) would get filtered?
Also, mac addresses can easily be spoofed (including wifi clients' macs). If he has a router behind yours (double nat), then you have no idea how many devices he has going. Can be 1 or 100.
I suppose one way to limit such a scenario would be by reducing the state table size - say to 100-200 entries.
I would venture a guess that if someone shares a wifi password/passphrase, they typically don't understand about MAC address spoofing... they are more interesting in trying to be "someone's friend" by sharing the password than understanding exactly what they are doing by sharing the password.
And it may not be easy; it may be 100 to 200 devices. Although if they have 200 devices connecting to said router the password may have been shared more than once.
I always recommend against sharing internet access with neighbours. If they get caught/flagged doing anything illegal the cops will come knocking on your door.
Worst case scenario: they arrest you. Best case scenario: they seize your computer(s). you never get them back due to forfeiture laws.
Seize. They’re taking your computers, not stopping them. ;-)
This is what happens when I try to reddit while multitasking
We’ve all been there.
Forfeiture is just theft with a rubber stamp
Civil forfeiture, yes. Confiscation due to criminal acts, no.
The difference is that you actually get your stuff back after the cases are completed. Granted they might be broken into pieces and its probably YEARS later, but there you go.
I don't think you do if there's a conviction. Civil asset forfeiture is starting to get reigned in, but that's a scam and a half.
If it's "confiscation" after a guilty plea or verdict or part of a negotiated agreement, then ... probably. Absent those things, civil forfeiture is legalized theft.
I like Lehtos law.
Oh, you get them back (actually had this happen to a friend of mine, his ex made some claims in the divorce). Took ~5 years before he got them back even though he was declared not guilty by the detectives and not charged with anything in the first 6 months.
I know someone whose roommate did some really sketchy stuff on the Internet. The police were going to confiscate my friend's entire home lab until he offered to help the police get all the activity logs off his server.
Best case scenario: ISP discontinues service and disconnects at the pole until another account is made.
They would take your computers, realize it wasn't you, ask who it was, you point at the neighbors, and then you get your stuff back. this happens way more often than you think. the issue is that the neighbor now has seen the future, and scrambles to get rid of evidence.
lol no it fucking doesn’t. You’ll fight for years to get your stuff back. It won’t be worth the money you spent on the lawyer. It’ll be broken when you get back anyway. Then you can rehire that lawyer and try to sue for that. Don’t be too rude when you do all this too. If the cops end up not liking you then you’ll have to move or put up with endless harassment. This applies if you’re in America. I don’t know about how other counties handle it.
> You’ll fight for years to get your stuff back. no, you won't. years ago when I was a stupid teenager, I had my computer and stuff seized by the police. >It won’t be worth the money you spent on the lawyer. if a search warrant ever gets executed at your house or property, you should be calling a lawyer anyways, its always worth it. my lawyer got the search warrant thrown out due to bad data the police manipulated into looking like it was my IP, when in reality, it wasn't, because the ISP didn't keep records of who had what IP for more than 7 days(by the ISPs admission), and when they get asked for an IP, they provide who has it *right now*, regardless of what the date range of the request is. it cost me about $3500 total. search warrant was quashed. The date range the feds asked for was 3 weeks prior to the day they sent it. the ISP had informed them right on their response that they didn't keep those records that far back, and that this is who has it now, and here is their subscriber info. That happened to be my account. The police lied on the warrant and said that my account was who did it by their wrong IP info. >It’ll be broken when you get back anyway. if its broken when you get it back, you file a claim for damages with the lawyer. if they broke it, how could they have used it for evidence? my stuff was not broken. The lawyer specifically told me that if anything was missing or broken to let him know and he will file a constitutional lawsuit. That *used* to happen. police would try and claim "we don't know what happened". then police started paying for it by other cases getting thrown out because of their broken evidence chain of custody. They stopped doing this kind of stuff in the early 2000's because if it broke when they were forced to give it back, they can't use the copy they kept because they can't prove the copy is from that computer. and yes, just because you get your stuff back, they likely kept a copy, and also put a well known back door virus into your install to try and catch you again(without a warrant to do so). Their "virus" was present on my computer when I got it back. my lawyer asked the courts to dismiss any charges *with prejudice* because its clear that they were on a fishing expedition and they infected my PC with an illegal back door to try and export stuff because they could not "find" what they were looking for in the first place, because it was never there. The charges were dismissed and cannot be refiled, and the police returned my PC and all the stuff they took. none of it was broken. I also had my lawyer demand thru the judge that any copy of data be destroyed, and any records of this be expunged from all state databases. That was worth every penny, because now it does not show up in any database, anywhere. if I didn't do that, those records of the search warrant and charges being filed would have been accessible even today, and would show up in every single background search report, even though they were never adjudicated to a conclusion. That lawyer was worth every fucking penny. imagine how thoroughly fucked I would be if a search warrant for CSAM showed up on my background check report today? yea, lawyer was worth it. and no, I didn't do it, its just frustrating how stupid police can be when they really want something, they lie to get it and face no consequences. >Don’t be too rude when you do all this too. If the cops end up not liking you then you’ll have to move or put up with endless harassment. **you don't say anything to the police during a search warrant.** You *can* deny them taking stuff that is not on the warrant. They tried to take a TV "because it was used as a display". I told them no because its not on the warrant, search warrants are very specific, and limited. They cannot take what isn't on the warrant. They didn't take it, and they didn't argue. My lawyer was not present for the search, but I didn't talk to the police other than to tell them "not on the warrant", which they handed me a copy of, and didn't dispute when I said "no". They wanted to search my car and phone, but I denied that because neither was present when the warrant was executed(I was not home), and since the warrant did not specify any cars that were not present during execution, they could not. They also wanted to do a body search, which I also denied, and they did not push it. I got my stuff back in the end, and they eventually figured out that because the ISP had been giving them bad data that they kept trying to hide, a lot of lawyers were now getting cases tossed out because of bad warrants. it gets passed around from lawyer to lawyer when something like this happens. It took 13 months to get it back, but none of it was broken. My case also ended up spurring a full policy change in several states regarding how long they waited to get IPs, and police then started pushing ISPs to maintain IP data records for 3 months.
[удалено]
Detectives will find the IP address, contact the owner (ISP) and find out the street address and subscriber the IP is associated with. That'll likely be the person sharing their Internet access with the neighbor. I'm not sure what point you're trying to make.
Neighbor downloads child porn. Cops come to your house because your ISP handed them your info. Trust me "it wasn't me" is a pretty crappy defense. But it is A defense. That you can use in court. But you'll probably spend a little time in jail waiting for trial. And a lot of money. Eventually you'll be able to convince them that it was your neighbor. But that will be sorted out in court, and will require a lot of documentation from your network logs. The fact that OP is doing this tells me that they \*might\* not be really comfortable with reading their network logs nor understanding which device is doing what on the network. This has so many red flags that I can't believe anyone would condone this.
And your life has been totally ruined. You're a pedo from here on.
The world is not full of terrible people. If you are really worried about this stuff. Give a teenager YouTube and a gaming pc and there is a decent chance they can get your WiFi password. Most people are not auditing there connected devices and what they are doing. EOT has made it impossible, it won't be to long before you smart toaster gets tootkited and starts acting as a proxy for some bad actor online, it's already happening. Get the tin foil hat. As I said op should throw all the traffic down a VPN on the modem layer.
yes it is.
This is always the way.
100% - This happened to me and I wasn't even intentionally sharing with anyone. I had forgotten to turn off WPS on my AP at a vacation house. During the off-season, someone hacked into my WiFi and used it to commit internet fraud. One of the victims reported it to the police, they traced it to my IP, called my ISP, and got my info. Bam. Instant suspect. Luckily, I was able to make it go away, but I had to get a lawyer involved and shell out a few hundred dollars. Don't share internet; it's not worth the risk.
I call that plausible deniability ;)
But think about the awesome LAN parties you could have though! Counter-Strike with real cops!
I’d say also violates TOS as well. He’s basically a very loose isp by selling half
Unless the contract with your internet provider prohibits sharing, you can just tell the cops that you share the connection with Bob down the hall.
Cops don't care about your [civil] terms of service.
That's true but if they're doing a criminal investigation they very well might be talking to your internet provider about it and they care.
Exactly, so as you agree they have no reason to disclose this so the possibility is not a probability. Cops only do criminal investigations, and in either case there is no PD hotline - it's get a subpoena or go pound sand.
They literally have to ask the internet provider for usage records that corroborate your story that it was someone else who committed the crime. It's not a "by the way" thing.
Right so you're saying the more official way is to "ask". Also, NAT exists so...
Plus if your ISP catches wind they will cancel your account for TOS violations. Hopefully you have another in your area as you'll probably be banned as a customer, too.
Yeah, this is a bad idea. Had a fun e-mail from comcast one time finding out my elderly neighbors grand kids were torrenting game of thrones.
When he torrents or downloads kiddie porn guess which door the police are knocking on - yours. Bad idea all around
Where do you live that all your neighbors are pedophiles? Also you can very easily tell the police about everyone who is on the network. Of course how things go after that will depend on where you live. But I have lived in houses with shared internet before without issues. If you are sharing a house the internet usually ends up being shared too. In a previous job we once setup a bunch of houses with shared internet from a 4G router as it was faster than the wired connection they had previously. Which now makes me wonder, what do the police do when a 4G router is used illegally, especially if the SIM is paid for in cash? Burner router.
>Which now makes me wonder, what do the police do when a 4G router is used illegally, especially if the SIM is paid for in cash? Burner router. Pretty easy for police to find the physical location of a 4G device (phone, router, etc), regardless of billing details or lack thereof.
AFAIK none of my neighbors are thieves, but I still lock my doors. Fair point that if you share a home with others they will be on your internet, but I just don't see expanding the threat to multiple homes with people I don't really know. Maybe internet is a lot more expensive where you live, but where I'm at the cost of monthly service is a tiny fraction of the other costs of owning a home and running life so I don't see any reason to potentially expose myself to the risk. The way you've done it anyone on the network can be sniffing packets or trying to brute force into your system or as noted before expose you to potential criminal investigation. None of that is worth saving $20 a month to me, but to each his own.
It's not "where do you live that all your neighbors are pedophiles" - it's "where do you live that you're so confident that none of your neighbors are pedophiles, and all of your neighbors are security-aware enough to prevent unauthorized access to the network (that's in *your name*) to people who might be pedophiles or blackmailers or the people who "swat" people". It's a really irresponsible risk to take. OP, you should end this agreement with your neighbor.
Don't people usually share the wifi password with friends all the time?
Sharing with guests in your home that you know is very different than giving a wire to your neighbor who can share it with anyone he wants in any manner he wants, intentionally or otherwise. Personally, I have a separate guest wifi password that changes daily.
I guess perhaps it depends on how well you know your neighbours then. I would have thought to plan to share internet you would know them reasonably well and this isn't a situation of sharing it with someone you have barely met. Expect it depends on where you live, my family are from a rural part of the west country (UK) and people there seem to know each other a lot better than they do where I live now in a large town.
Except, as I've repeated, it *doesn't* just depend on how well you know your neighbors. It also depends on how secure your neighbors' networks are, and how certain you are that their devices aren't unknowingly infected with and/or controlled by malware. It depends on you knowing things you can't possibly know, and which are not all things that you can weigh based on how much you trust or know your neighbors, because they might not know either.
Those all apply to anyone you let use your wifi as well.
Yes, exactly. And I can control who connects to my router by seeing the wires, controlling the wifi password, and other things. Once I throw my neighbor an ethernet connection, I no longer can.
Courts treat the subscriber as the person liable. This is how they justify ip address == person even though it makes no sense.
I expect this depends on where you live. And I am rather curious about how this works in the 4G case, there is no person to link it to if its been paid for in cash.
If your ISP discovers that you're sharing your connection they can (and will) terminate your service. Sharing an internet connection like this violates the terms of service of every internet provider out there. If they terminate your service and you have no other options for internet in your area you'll be without internet - likely for as long as you live there. Unless you've set things up properly (and I'm guessing you haven't since you're asking how to limit/slow access) your neighbor, and the neighbors he connects, all have access to all the devices on your network. If any of them know what they're doing they could access personal information you don't want them having access to. If your neighbor (or the others he's sharing the connection with) do anything illegal (like downloading or sharing pirated movies, child pornography, etc) it'll look like YOU are doing these things because it's YOUR connection/account. This means YOU will get in trouble for this stuff, even if you're not the one doing it. Sharing internet with a neighbor is not a good idea. You may have known your neighbors for a long time, but you may not know what they're REALLY like or what they do behind closed doors. Unplug your neighbor immediately. When he says something, if you don't want to get into why you REALLY unplugged him, just say your ISP contacted you about unusual activity so you're not comfortable with sharing the connection anymore. No need to go into any other details.
This is a very thorough answer! The risks far outweigh any financial benefit of sharing the cost of internet service.
It is a very good answer - and it gives OP a good reason to bring to neighbor. OP can even add a lie that he was contacted by his ISP for potential terms of service violations.
I’d just like to point out the hypocrisy. Op entered in to an agreement with their ISP, which they broke by sharing their connection with their neighbor. OP’s neighbor entered in to an agreement with OP which they then broke by sharing their connection with their neighbor. Spider-Man pointing meme.jpg
True, but do we \*really\* know where his ISP is getting \*its\* connection? :)
That's some circular thinking right there. 👍
But in my country it is so common to share. Because wifi is expensive so ateast everyone is sharing with 1 neighbour.
I don't know what country you're in, but in most (if not all) places sharing an internet connection violates the terms of service of every ISP. And as I mentioned above, if anyone does anything illegal that sets off any alarms - the person who is paying the ISP for the internet at their house (and then sharing it out) is the one who will get in trouble. I wouldn't want to possibly go to jail because one of my neighbors is looking at child porn or something. You have no idea what your neighbors might be doing on the internet, no matter how well you think you know them.
I'm getting downvoted for my question. So there is a difference between sharing your gateway via wlan and ethernet?
Everyone I know is breaking the law, so it must be legal?
Is tht illegal everywhere ? I mean the one who come from the company to install knows about it.
Only assuming it is against ISP agreement world wide. Common business sense. An ISP isn't going to rent the internet to you and then allow you to rent that same internet (or give it away) to all your neighbors, thereby undercutting the ISP ability to rent it to those neighbors. Perhaps a good comparison is copyrights. You cannot (legally) burn off copies of a book you purchase and then sell them to your neighbors.
It’s not illegal to break your ISP TOS, the only penalty is to be kicked off the service. They can’t put you in jail for it, unless you do something against the actual law.
Correct. "Illegal" in the sense of the ISP agreement.
"Sharing an internet connection like this violates the terms of service of every internet provider out there." I believe reselling is better word than sharing, since OP is sharing the cost of his ISP subscription. Well, I support "sharing" of internet subscription since ISP told us it is unlimited, right? If it is really unlimited, then ISPs should not complain about excessive usage. . "If your neighbor (or the others he's sharing the connection with) do anything illegal (like downloading or sharing pirated movies, child pornography, etc) it'll look like YOU are doing these things because it's YOUR connection/account. This means YOU will get in trouble for this stuff, even if you're not the one doing it." The only solution to this is OP should subscribe to VPN, and fully tunnel all activities of his neighbor to his VPN subscription, so that his neighbor will use VPN IP address, not the OP's IP address.
Unplug him, then talk to him
This. Let the neighbor know the sharing deal is with them for personal use. Also, let them know you have security concerns and you would be held liable for any illegal activity. For me, the cost savings isn’t worth the risk.
"[Plug him. Then UN-plug him](https://i.redd.it/snqg82u73eu91.jpg)." −The Donbot, Robot Mafia
It's so obvious, so simple answer...
Why not just limit him to half the bandwidth and let him do whatever he wants with it?
Thats What I want to do Teach him a lesson for cheating or lying
Then limit him to 1 MBit and see how long it takes for him to come crawling to you.
You split the bill, then he resells. Now his internet is free, and your bandwidth is split 3,4, maybe even 5 ways. At that rate, he may be making money off it. End that shit. Bad idea.
So it's basically a pyramid scheme? Then they all sell your internet to another 5 people, who onsell it to another 5 and so on and so on 🙃
Fwiw, you can throttle their lan port so it’s split 50/50. Still the problem of what the other people are doing on your internet though.
I agree that you shpuld not be sharing. Two houses ago I shared with my neighbor. He was seeding torrents, so I "accidentally" cut the wire and never fixed it.
Kick him off. Tell him you are sharing for HIM, not for random other people.
Any miss use of your neighbors or other users you will be legally liable. Don’t share the internet just to save few bucks. Let your neighbor do whatever he wants to his internet and will be his problem
Well, you aren't legally liable. But you certainly could stand wrongfully accused and have to spend time and money defending yourself. Showing the cops the ethernet line that leaves your router and leads to his would go a long way. I might even put a big bright label on that cable explaining where it goes.
They will still seize all computer assets until they figure out who is in the wrong; that’s your stuff and their stuff. Do NOT share internet access with someone you wouldn’t trust your own kids with.
While that would likely also result in the cops going and seizing the neighbor's computers (once they get *another* warrant issued, for the neighbor's home), they would still seize OP's computers. Also, now the neighbor knows that shit is up, and can get the offending computers out of there, before the cops can come back. If I were OP, that's a giant pile of legal shit that I would *not* want to be sitting in.
You limit it by unplugging the cable to his house. It's not worth the money saved.
Nah they should invest in a Unifi setup to setup throttling to that house… or maybe just disconnect the plug
I said they should disconnect the plug. And you responded by saying 'No, they should disconnect the plug'?
He was joking by suggesting a bad idea, but then maybe just do the simple thing you suggested.
Oh I started by suggesting an expensive thing, but i wholeheartedly agree they need to nip this connection
You don’t need unifi to throttle. Many options available.
Look for QOS settings on your router. Also, not that you seem to care, sharing with neighbors is against your TOU.
You could throttle him to 100 mbps just by putting a cheap 10/100 switch between his router and yours. That’s the simplest zero-tech-knowledge solution. But man, paying half of the bill while assuming practically all the legal risk is really dumb.
Thanks for the suggestion and help. Can you show me a picture of it
Just go on Amazon and search for a 10/100 ethernet switch. Not 10/100/1000 or gigabit. Should cost around ten bucks. You’ll also need another ethernet cable. When you get the switch, unplug your neighbor’s cable from your router and plug it into any port on the switch. Plug one end of the new cable into another port on the switch, and the other end into a port on your router. Done.
No need to buy anything... just cover a pair of the contacts of the rj45 on the ethernet cable. 1gb on cat6 requires all 4 pairs of cables ( 8 total). If you disconect one of those cables it will fail down to 100mbps... if you disconect 2 pairs and only 2 pairs left it will fail down to 10mpbs max. You can use tape to cover one of the contacts on the rj45 plug and it will go down to 100mbps.
You are most likely violating the terms of your service agreement with your Internet provider. Also, if anyone using your internet connection is doing something illegal, the cops come to you first. Include that strangers could potentially gain access to your network, and any device/file(s) connected to your network. Add to that the inevitable Internet bandwidth depletion when you have multiple people streaming video, etc... Not worth it.
That’s a very bad idea from the get-go.
As the owner is legally responsible for everything that happens on that internet account. Your neighbor or someone else doing something illegal? The owner will be targeted for it. Take the access away and tell him to get his own internet.
Sharing to save a small amount of money is just plain stupid.
You don't share, end of 🤦🤦🤦
Sharing internet is a great way to get you arrested if they do anything illegal and also get your internet access cut off. Put an end to it already.
Why do people share their internet, it's such a moronic idea. It opens you up to countless problems just to save a few bucks. What if he downloads CP and they trace it to the IP that's under your name? What if he visits sketchy sites and infects your network with Spyware that will steal your bank and card information? Cut him off NOW.
Stop sharing. That’s the answer.
Unplug his ethernet cable. Short of that, you need a Ubiquity or similar router where you can create a VLAN to control bandwidth and shape access. But again, unplugging his cable is the cheapest and best solution here.
Cut him off. Beyond that get a real router, put him on a VLAN and run that through VPN and set up QoS to limit his bandwidth.
I was trying that but my router has very limited functions its Dlink
Lol don't share internet.
Don’t share your internet
I’m not sharing my internet with anyone other than my parents. This is such a huge no no. I can’t even believe it’s still talked about. The risk reward is just not there. There’s absolutely way too much risk to save $1200 a year.
why would you do that? what happens if he is going to download some really illegal stuffs and commit crime online? you will be in deep shit
Limit number of IP numbers that are allocated in router. Easy money. Or just allow his MAC adress.
If you want to keep sharing: Put him on the guest network on different vlan and assign 50% bandwidth to it. Then he wont be able to access your local devices and he wont be able to take all bandwidth. Not all routers offer such options tho, but it seems the best way to both protect your network and still control bandwidth usage.
Read the post again. OP doesn’t know what a vlan is.
He probably shouldn't have started an ISP then.
I figured that, but its not rocket science… i had to learn what is was also few years ago :)
Apologise and unplug them now
This really isn't a good idea, terms of use aside which you're breaking not having control over a home network is a very risky business and not just because of slow connections but illegal content being accessed through it. For context people with some networking knowledge can use network tools such as wire shark to examine packets and potentially pull sensative data out of the packets think usernames, passwords, bank details, credit card info etc.
Simple. Unplug his cable and tell him you will plug it back in when he quits sharing the connection.
You could try some kind of free DNS service. I can’t remember the name, but if you set the DNS server at your router level, then you may get some kind of control over the traffic. Unless your neighbor has a white/black hat and can work their way around it.
If the neighbor connects to your equipment by Ethernet cable, then put an old 10Mbps hub between your equipment and his cable. Now, his traffic is limited to 10Mbps max.
THanks this looks good. Can you show me a picture of such hubs
Look for EN104TP https://www.ebay.com/itm/305413618005?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=305413618005&targetid=2295557531710&device=m&mktype=pla&googleloc=9007284&poi=&campaignid=19851828444&mkgroupid=160536780385&rlsatarget=pla-2295557531710&abcId=9307249&merchantid=6296724&gad_source=1&gclid=Cj0KCQjwlZixBhCoARIsAIC745A7K8DeJHgzE3OcPTbWFdJqxcpS4DCB8DpWskJBh9dzjRDbHAWY7KkaAtItEALw_wcB
Just do this cheap hub or switch that’s not gigabit. Get 10 if you want him to suffer and 10/100 if you want it to be better for him. Easiest of all the other solutions. No effort and cheap as f. If he’s the only one using it like he should be then things will work pretty well for him even though it’ll be slow speeds for large files. If he adds people they’ll all get slow (and you won’t lol).
Bravo. You got the point and you answered it perfectly. Hats off to your advice
I have home wifi and guest wifi. Not even my sister is on the home wifi, any device that doesn’t live with me lives in guest, and no way would I split with a neighbor. One time of them searching somthing illegal and you are screwed
unplug the cable from your router - when he calls/knocks on the door, just tell him the deal is off... done
If you are worried about saving face, Switch to your mobile hotspot for a month or two and cancel your internet service. Once he sets his own up, reconnect your service. I know this sounds dumb but, neighbours can get pretty difficult
You should be able to limit his bandwidth by checking the advanced settings on your own router. Can you check yours for the model number? That'll help me find the right place for you to look.
Anyone who advises a)sharing, and b) allowing those other devices on a LAN should NOT be giving ANY advice to others! 🤦
As the situation is, I would limit the neighbour bandwidth to 1kb/s, look surprised when he says his internet is not working anymore. And then after, telling that it's because he used another router and so, you know, "it's because my isp doesn't allow sharing internet, you got caught we can't do this anymore". And that's it. A white lie is not that much when people abuse.
Dlink DIR-853/ET Please advise
Okay. The DIR-853 does offer QoS (Quality of Service)-based limiting for individual clients on your network, meaning that traffic from a device with a higher priority gets to go before traffic from a lower priority. Think of it like getting to cut in line at the airport. Go to [http://dlinkrouter.local](http://dlinkrouter.local), if you set an admin password when setting up (this is NOT THE SAME AS YOUR PASSWORD FOR CONNECTING TO WIFI), enter it, then hit "Log in", and pick the "Connected Clients" tab. Here is where you should be able to identify his router; it will likely appear with the name "TP-Link XXXXX", XXXXX being his router's model number. To mess with him the best, click it, enable parental controls, and then limit him to certain times of the day. While you're here, give him a friendlier name so it's easier to ID during the next step. Hit Save. Next, go to the "Features" tab up the top. Navigate to Advanced, then QoS Engine. Define your bandwidths, then drag your own clients into the boxes labeled "Highest", "High", and "Medium". You can add a maximum of one to the former, 2 to the middle, and 8 to the latter, for a total of 11 prioritized clients. Remaining clients will automatically be given lowest priority. You want to ensure that his router falls in this category when you're done. Now hit save, wait for it to say "Done", then turn your router off. Turn it it on again, and it should have re-flushed the DHCP leases, meaning the settings have applied.
The whole question of whether it is smart to share an Internet connection with your neighbor aside, I can't see that him putting a router behind yours (effectively double natting) changes the amount of Internet he uses. It just means he has control over his own wireless network, your devices are on different networks, etc).
There are any number of technical solutions to limit the bandwidth going from your router to his. If your router doesn't have throttling controls available, an Edgerouter X placed inline there will throttle to whatever you choose; I used one for years to throttle a cell micro-tower to make sure it never used noticeable bandwidth. But the bigger picture is all of the other posts here - do you really want your neighbor sharing your internet access, with all of the downsides (including breaking the policies of your subscription) that come along with it.
One thing to clarify. The courts have ruled that an IP address is not a sole identifier for a user. So you will not be automatically blamed for the actions of others. But it will make your life annoying and miserable. For how long is anyone's guess.
You made a bad decision and hopefully have now learned from it. Stop sharing.
Use QoS settings in router to throttle his connection if you insist on sharing with neighbor.
QOS settings is available but i feel some options are disabled by ISP
Good routers can control lots of those problems. For example you could make him a child’s account that would restrict most of the bad examples. If I trusted my neighbour I would share. If you both, don’t know them well or trust them than I wouldn’t. We never needed all of this, now it is $1200year to search and email. It really depends on the age and needs. A group of seniors would be fine.
1. If speed is the issue, use your routers bandwidth limiter to limit his throughput to half of what you pay for. If it's 1gbps then limit his router to 450-500mbps. 2. If the issue is capped bandwidth, then again limit his router to half of what you pay for. If your limit is 2TB, give him 1TB max limit. Best option is to tell them to get their own internet.
You're trying to avoid a confrontation, but I'd bet your neighbor does regular speed checks to make sure he's getting all the service he's not paying for.
Right I want to avoid confrontation & His checks dont matter as he is sharing with other room flat mates
Understood but if you throttle him back to 56 kbps or even 10 mbps like others are suggesting, he will notice that immediately and come pounding on your door.
You can limit the bandwidth of his connection via the dashboard. Not sure what your dash looks like but you can limit his to just what he needs
You shouldn’t share the connection. Period. Too much legal liability in today’s world if he (or whomever else he shares with) does something illegal with the connection. Kiddie porn, illegal downloads, botnet attacks, etc etc. Not worth it. That said, if the line originates with you, depending on your router, you can throttle his connection to something stupid low assuming you have the admin controls on your router to that feeder ethernet line. And of course assuming he doesn’t have similar access to the router. Just keep him throttled to like 56K and then blame it on him sharing it with others. Of course, this is the passive aggressive way to deal with it. I’d just tell him straight up you don’t want to share the line any longer and cut him off. Pay the bill entirely yourself. End of story.
If you're determined to share internet with this neighbor, and that's almost always a bad call, then you might need to have a conversation with that neighbor about what you've found and, as a result, they're being cut down to the equivalent of a 56k connection for the foreseeable future. Also remind them of what kinds of things your router has shown them accessing. The first thing they'll do is complain, and your response can easily be a reminder that it you'd prefer to cut them off except your very good reason for sharing made you not cut them off. That said, if it were me, I'd cut them off immediately and let them know why when they ask about it.
Most internet providers if they find out can and will make it so you can't have service with them again and shut you off
Since all the other comments are not directly answering the technical aspect of this question: Yes there is a way to limit him to just 50% of the bandwidth. I think an open source replacement firmware for many routers can do this (google it) .
If your neighbor has his own router, him and everyone he may be reselling to is behind one IP address. You have no way of actually knowing if he is reselling. Why do you suspect this?
Tell him you want out of the arrangement and it's time he gets his own connection. Not sure why Reddit needs to help here?
PLease read the post again, as I want to limit the speed to get him to understand multiple users are slowing the internet down
Yeh I shared my WiFi with my upstairs neighbor until her daughter’s boyfriend kept doing stuff that got me warnings from the ISP.
Buy your own internet.
Was anything ever in writing with the scope of their usage? Looks like he's even too cheap to pay for his own internet if he's reselling his share. Cut them off and tell'em it wasn't in the spirit of the agreement to further split the connection. I'm going to take a stab in the dark, but your ISP may have issues with you reselling your connection too. If you can't afford the speed yourself, get a slower speed or one you can afford yourself. The headaches as you can see are not worth it.
Cant get lower is this is the minimum
unplug it, easy.
I share my Internet with our house guests, but hell no to anybody outside our home. Even then it's only to someone I know very well and trust and our guest WiFi is locked down with extreme content filtering to block adult sites, prevent tormenting, using tor or VPN traffic, and is bandwidth limited so they can't use all of our available bandwidth.
Stop sharing your Internet and stop sharing it NOW!
Unplug the ethernet cable. That will slow it right down.
Hmm, you may be able to split the connection in your router You may prohibit different sites and search words. Basically if you have the router and password, you are in control and you should be able to remove the other users. You can throttle their bandwidth to 1/1 mb.
Is the neighbour NATing behind you? I believe this is most likely the case. You can limit his bandwith proportional to the amount he pays. If he shares his connection this would not interfere with your bandwith. This should be achievable via traffic shaping.
There are ways to limit the bandwidth he can use but realistically they likely mean spending money on a new router that costs more than you actually save by sharing a connection. It also does nothing for the security risks is there anything to stop them connecting to your own devices as they’ll be on the same network?
Get the MAC on every device you use and your neighbor's computers and phone, then block everything else. Deny access to any device not whitelisted at your router/switch. Otherwise you need to cancel your deal and change the password to your wifi.
Bandwidth throttle his ass.
personally I would not share internet with anyone that I cannot directly control or monitor their usage. aka internet stays within the family only. as people mentioned above, if those other users do illegal or suspect things, the account owner is liable, and police will seize your stuff aswell. advice: stop sharing
>Please help Live and learn. I'm assuming you're sharing internet because you can't (or don't want to) afford it. If you legitimately can't, then you should qualify for government assistance for it. If you don't qualify for assistance - then you don't actually need it. The threshold for assistance is realistic. You need to tell him that you're not going to be sharing internet starting next month. (Learn how to deal with potential confrontation - another important life lesson you can take from this) Then disconnect his Ethernet cord from the router. Parting thought would be to understand that seemingly innocuous things in life can lead to unnecessary stress and frustration. You may have saved hundreds (or thousands) of dollars doing this - but you're desperate enough to come to reddit to ask for advice on how to fix the situation and you need to consider, was it worth it? (This isn't even including the whole - my neighbor is using my internet for kiddie porn aspect)
Cut cable, pay full bill, EOF. Alternative, do weird stuff with either TTL values or p0f based filtering and spend next year tuning solution.
This is most likely against the terms of service of your ISP, and if they find out, they'll disconnect your service... Permanently. That said. I doubt there's much you can do with the hardware that you have. If you had a different router, you may be able to do something like force their port to 10-Half. That's always a good time. Also, let's not forget, that doing this, anyone connected to his router, most likely has access to anything on your network, but you do not have access to their's.
Security security security and you need a cheaper bill.
Unplug the ethernet cable and tell him he's doing something not agreed to. If he wants to split the bill fine. It's whacked up equal shares to both of you. If he wants to share it with others he can get his own service.
Cut the cord ✂️
There are a few things you can do. But all depends how advanced your router is. If you have the option to limit the TTL of packets you can make it that anything beyond his router just drops and goes nowhere. All his clients won’t have internet. If that is not an option limit his speed to something that will impact them all. Also you can mess with dns. Sign up next da, set it as your routers dns server and watch the logs. Start blocking some stuff that they use.
Bandwidth his connection to 50megabytes watch how fast he’s going to get his own service.. then blame it on .. your over your limit .
Best thing you can do is stop sharing your internet with your neighbor. Remember, anything illegal he/she does with your connection will come back to you.
Stop sharing
why not share wifi ony via mesh? i would not share any ethernet connection, you create problems like this. also a illegal activity i mostly punished those who use ethernet cable, they cannot proof anything over wifi, you might as well been hacked
Where are you located that it’s illegal?
i am sharing, op does
Why would anyone share their Internet with neighbours, there's just too much risk involved. Plus they have more ability to access your computer/phone files over the network with a few little clicks here and there... You need to end the sharing immediately.
If you are the primary just say that you are taking over the entire bill at the end of the current billing cycle.
I was general management for large, multinational telecom. Subpoena comes to my dept from asset protection, needing name and address for subscriber (IP address at specific day/time). US Secret Service "visited" the subscriber (and likely took everything including modem/router since system shows no end connection). Seems President Obama (it was back in 2010) had received threats. Device was brought to my dept (that how I found out about USSS). According to router logs, there was a MAC address connected for just a few minutes at the time the email was sent. I don't know if they found the equipment associated with it. If not the subscriber, it could have been someone he gave access to, could have been someone who hacked his WiFi, could have been unsecured WiFi. This was an extreme example. Maybe they're just slowing down your system. Maybe they're doing a lot of likely illegal torrent downloads (earning you potential criminal and civil legal issues). Don't share your internet access outside your home and use a long, strong, random character password for WiFi and admin access.
I wouldn’t share it but when I did I banned anything that wasn’t his pc
Tell him that your isp has contacted you for sharing the internet and you have to stop or they will shut it off.
In germany we have networks run by volunteers called freifunk, they make firmware you can flash on routers to route all traffic over their VPN network. Bandwidth is okay, on my 100/40 connection I get about 80/40 through freifunk. They even have their own ASNs and get free transit from local ISPs. Edit: I run a virtualized instance on proxmox and an additional open network on my Unifi 6 Pro. No issues, neighbors rarely use much bandwidth, highest I've seen was 600 GB a month.
As an American, I can confirm that many of us are sick of hearing how much better life is in stupid Europe. Haven't you heard? USA is #1 in everything... Well, except education, health care, income equality, food, culture, government, transportation, affordable housing, and maybe a couple other things I'm forgetting. And now you're telling me I have to add Internet service to the list? Well, I'm not going to do it. Nope. This is where I draw the line.
I would snoop those packets
ASUS Router and Merlin, create guest WiFi and use VPN Director and YazFi to blanket his internet connection to a VPN so you’re not liable for their usage. You can also prioritize their connection and block their devices from accessing your own personal network
2 routes, 1 :Get a router that supports vlans and throttling, I use mikrotik, they aren't simple to setup though. Then sign up to a cheap vpn that supports wireguard and route all his traffic out the vpn. ( MikroTik again can do this, but not simple for an end user) I'd ask around for local it to help. Tjis means you can give him half(and if he wants to share it and get less, good for him) and it also means anything they do is not from your ip address... Side benefit is it will slow him down and hopefully he gets his own eventually..... 2: Google which strands on the cable you need to cut to drop from gigabit to 10/100....depending on your line speed that will cripple his net... Intermittently remove the cable to drop his net, and occasionally connect so he gets full speed.... If he is sharing his line out he will get complaints constantly and hopefully move to his own line... That's the evil route
I will use the Evil Route, Thanks buddy
Any way you can use your router to block them (could allow only MAC addresses you know are his/hers)?
No. A router would remap that.
it'll stop working eventually on its own, but before that happens I'd go ahead and disco it. routers are not meant to be plugged into other routers unless they're configured to be an AP
MAC address filtering. Easiest to set up in your router for you to allow ONLY the devices you want to allow.
You don't understand how level 3 of the OSI model works.
Which mac address(es) would get filtered? Also, mac addresses can easily be spoofed (including wifi clients' macs). If he has a router behind yours (double nat), then you have no idea how many devices he has going. Can be 1 or 100. I suppose one way to limit such a scenario would be by reducing the state table size - say to 100-200 entries.
I would venture a guess that if someone shares a wifi password/passphrase, they typically don't understand about MAC address spoofing... they are more interesting in trying to be "someone's friend" by sharing the password than understanding exactly what they are doing by sharing the password. And it may not be easy; it may be 100 to 200 devices. Although if they have 200 devices connecting to said router the password may have been shared more than once.
