Hi,

my room mate and I share the internet connection in our house. I've started getting packet loss and higher ping in games but he claims that he's not using the internet for anything. However, when I unplug his cord from the router my ping drops back to normal. Is there a way to limit his download and upload speed? I couldn't find an option like that from the router settings. Or could there be other ways to solve this? I use a dynamic IP at the moment, would it make any difference if I changed it to static?

Thanks

Does not appear to be. You would need at least some form of QoS and this router has none.

If he claims there is nothing running then you need to look at the machine and find out what it is up to. Many times you load games and such and they leave a torrent client running in the background almost like a virus.

I would start with the resource monitor and see if you can tell which program is generating network traffic. Worst case load wireshark and capture all the traffic going in and out of the machine...it can't hide from wireshark.

And the only way to monitor his network traffic is through his computer? It'd feel awkward to tell him that I doubt him :p is there no third-party software that acts as a QoS?

Again it must run on his machine.

You would have to insert a server between him and the router to accomplish what you want. You might get lucky by playing with the firewall options in the router. You could block his ip and see if you get messages about what it is blocking.

Do you feel better about not just doubting him but acting on those unproven doubts to go behind his back to throttle his access?

The approach is not to assume he is lying but to bring him in as a friend and collaborator in solving your problem. With something like this, " I've done everything I can think of on my computer, can we look at your machine together and run a few tests for comparisons to make sure there is nothing I've missed?"

You don't have to tell him all your looking for. It isn't lying not tell him all your suspicions. They are not accusations or conclusions, just hypotheses to be tested, confirmed or falsified along with others hypotheses you are working with.
