As of a month ago, I have been using my Roommates router to connect to the internet. As of recent i have been getting disconnected from the internet while he is still on the internet. I would get disconnected and then a few seconds later i would be reconnected. Sometimes i would be disconnected for longer periods of time and i would restart in order to connect again. My local area connection icon in the lower right hand corner of my screen would say i'm still connected though. But then sometimes the icon would say nothing is connected when i have the ethernet cable connected. I would take out and put the ethernet cable back in and it would say i'm connected again. I've run several virus scans to see if I have a virus. I've switched ethernet cables. I've asked my roommate everytime is he downloading something and he says no. I've run out of ideas what it could be, unless my roommate is lying to me.
