every PC on my place is connected through LAN and to the internet through 1 router (not sure if they use router).

the thing is, every time this dude is online, the internet traffic went bad, and i don't have any choice but sit tight and use my NetCut to cut him off, but apparently he'll report to restart the modem, and i'm just going in circles

is there any way for me to also disrupt his connection, but doesn't make him disconnected? just make him slow or something

even if i try upload a lot of things, the ping wont go up anymore (i ping google)

usually it is 50 ms when it is normal, then when the dude is online, it goes everywhere from 200 ms to 500 ms, sometimes i try to upload things, but the ping never went up past 500 ms, as if my connection is limited and his aren't

actually the win/win solution i can think of is setting the QoS from the router, but i need a way to access it, can you guys help?

From the sound of it, it sounds like you're in an apartment or other shared resource area (dorm). The best thing to do would be to complain to the people who own the network.

Be a minor pain, have screen shots and other ways of showing the problem (graphs are nice). If the network is included in your rent, point out you're paying for a service you can't use because it has too much traffic on it.

If they ask for suggestions tell them to set up QoS, and do bandwidth monitoring to see what the dude is going to. Not hard to set up BandwdithD and NTOP on something monitoring the connection to the upstream from the router.

There is also the chance that the guy doing it, doesn't realize there is a problem, and his system is compromised.

I'm not trying to be flippant here, but have you thought of introducing yourself?

As they say, you catch more flies with honey than vinegar...

"Torrents? I've never even heard of those, officer! Someone must have hacked my computer and downloaded all those movies!"

Seriously though, if you're not the administrator, there really aren't any ethical actions you can take to remedy this. You could also try applying some economic pressure and ask for a discount on rent since the service isn't up to par. Otherwise, explore getting your own service or going somewhere else.

Probably nothing that is legal or ethical.  Sorry man, you are at the mercy of the owner of the pipe.  Can you get your own line?

no prob, i don't even want to hack it if it is possible (hence i asked to fix it from my side only), they are still people i live with


if that is the case, is there any way i can check it? for some reason, i think its either this or torrent, but even then when no one is using the internet here, i tried using torrent and the maximum ping to google i can reach is 250ms, i do wonder how this guy made all the way too 600 ms, i don't think he knows what is he doing either

You have crossed the line from ETHICAL to CRIMINAL. Chances are you will get Zero help from here now.

^alright, i won't touch anything beyond my own computer, but is there anyway to get my own computer set up have better connection? or none?
