Ok i dont know what is going on with my xbox 360, but if someone could explain that would be fantastic. whats happening is i can sign into xbox live, then i go to play a game of gears and no matches found??? then i go to HALO when 1mil people are playing online, and i can only find one game.??? and when i get there i cant even move because its so laggy?? Then i sign myself out to test my xbox live connection and my MTU failed the test what do i do to make my xbox live run smoothly again??
