Ok, here's the problem, my 360 and my brother's 360 are connected to the same router. When we both turn on our 360s we both log in to xbox live. If I play a game I'm still login to xbox live, but if my brother pops in a game it logs me out of live and I can't reconnect unless if I goto the Dashboard, but if I pop in a game, while my brother is login to live and is playing a game on live, it will log my brother out of live, but let me play on live, and my brother can only login to live when he is in the dashboard, this resently is happening today, hasn't happen before just today. Things I ruled out: - cables being loose - cables - ip might of been the same - the router - the modem - internet service prodiver Things I tried: - resetting the modem - resetting the router - tightening cables - loosening the cables - different cables - new cables - switching cables - moving the 360s around the room - resetting 360s to factory defaults - erasing cashe Things that I think might of been the problem: - I put my Hard Drive in my brother's 360 and tried to get live, but didn't even load the window with the type of live bundles to buy. It just let me press A on the ad, but didn't load anything. Please help me out bros.
