My room mate isn't using my routers, he's aware of the issues and has tried helping me. I've used many different SSIDs for these, none of them with the same name as one of the other connections in the area. My roommate's modem is about 20 feet away, and he keeps the wifi off for the vast majority of the time, as it interferes with his work connection. It was off when the issues began, and has only been turned on a few times so I could use it when my connection was down. It's been there for a few months, and I haven't had problems with my network until the last few days.
