I got a 4gb Xobx 360 slim a few months ago and it used to work totally well. after a few weeks it started to have really bad connection problems, where I had to do a connection test almost every time. Now the xbox cant even see my wifi! I have never done anything to it, that would damage it, and its been sitting in the same cabnet since I got it. My wifi provider is comcast, and all my other things connect just fine. (Computers, iphones, and my PS3) Anybody knows what the problem is, or what to do to get it fixed??
