I recently moved in with some friends and I'm having trouble connecting to the internet upstairs in my room, but downstairs there's no issue. The thing is, I don't lose connection to the wireless modem. I get nearly full connection while upstairs but still cannot connect to the internet. We have comcast internet and with my two machines there are 8 connections to the modem. What can I do to get my computers to connect to the internet while i'm upstairs?
