I've been playing MW3 on my xbox in the same room as my brother and we both have our xbox's hooked up to the router using ethernet cords. While playing in the same lobby he disconnects and I even though my connection doesnt get interupted. We've tried using wi-fi on the slim but it still disconnects from time to time aswell. The computer works fine and my xbox does, but my brother's keeps on disconnecting briefly from time to time. I don't know what is causing it but it's getting very annoying as we can't seem to play more than 2 games together. Any suggestions?
