I've been on xbox live since September 2010, with the old model. All of a sudden, I can't connect to live in my room. It says to make sure an ethernet cable is plugged in, it wont detect it. I'm positive that the problem isn't the wire, because I've used several wires(4). I even brought it into my living room, and plugged directly into the modem where all 3 of the cables worked, and I played on xbox live there for 2 hours. I'm using the same wall jack for this desktop computer im using right now, and the connection is fine. It's only this room in the house it doesn't work, and in this room the only thing that wont work is the xbox. Please help?
