I live somewhere out in the woods in Southeastern PA, I have comcast cable internet, one of the white RCA modems they gave me, and a D-Link Wireless router. Whether I have my computer wired or wireless hooked up, the connection is basically terrible, it goes out when i'm downloading a few things and going on a website at the same time, i download at like 5 kb/s, I just don't know what to do, we had comcast come out and put new ground wire in, and some booster in the basement, but still, the connection is terrible and it is starting to drive me crazy, any advice?
