i have a fast connection,i play gears of war live all the time and it works perfect but when i go to matchmaking on halo 3 i enter a playlist,and then it gathers the players and the map starts loading, but then all the players disapear and then it says cant connect to messenger and it says disconected from xbox live,its really annoying becuase i want to play and i have to test my connection to get back onto live all the time (it only happens to halo 3)
