I have two PCs on my network; one is a Windows 7 PC and the other is running Ubuntu 12.04.
My PC is the one with Ubuntu and it is slowing down the network not only for me but for my husband as well.
I have used
iftop to check out the network traffic and there is none, yet speed tests show that when my PC and only my PC is connected, the speed goes down significantly for both of us.
I need help troubleshooting this further because I have never seen anything like this before...
