My roomate recently purchased an Xbox and ever since has has whenever he starts playing online it will disconnect me from Xbox live. When i perform the connection test everything works fine, until it gets to Xbox Live and it will only load the first bar. Once he gets off everything gets back to performing the way it should. We are both hard wired to the same router. I have tried everything I can think of to solve this but nothing works and it doesn't make sense. I don't affect his connection at all but he kicks me every time time. The only thing i can come up with is maybe its a bad router, but even that doesn't make sense to me. PLEASE HELP!!!!
