Disconnecting from online game

[British_Command]

I have recently purchased a new BT hub router, this has been working fine apart from when I play on Xbox Live in multiplayer online games. Its become a repititive problem that I keep getting disconnected in the middle of an online game session.

Could this be conflict in wireless frequencies? As I do also have BT phones, or could this just be a simple configuration problem?

This didn't happen before with a previous router.

Thanks.
