I have two wireless controllers and both disconnect multiple times per hour making online gaming almost impossible. I have changed batteries, resync, hard reset, and sit about two feet from my console. Both controllers work fine when wired to the console. I sent the Xbox in for repair and it's still disconnecting. I called again to say it's not fixed and need it repaired and they said it's no longer under warranty. What gives??? I have a lot of money invested in this console and you won't repair it?
