I'm using the official headset wireless ( the old not the blutooth one ). Sometimes the headset disconnect to the chat and reconnect 2 secondes after, while it's reconnect the game make a freeze.
and sometimes the freeze disconnct the Xbox live, when i make a test, xbox said : you need to plug a WiFi adaptator ... Ok ?! I have a slim one ... so the adaptator is on the xbox ...
To reconnect on xbox live i need to plug off the ac/dc cable to the xbox and wait 5 sec before i plug ... atfer that the xbox reconignize the wifi adapter.
