For months I'd been trying to figure out why I was always being disconnected from Xbox Live.
I have finally found the problem, it's my surround sound system. The two back speakers are wireless and appear to be interfering with the Xbox. Every time I am disconnected, I turn off the SS unit and I can connect again, but immediately disconnected once I turn the SS unit back on.
Is there a way to fix this without moving things around? I have limited space to put things and don't want to have to put the Xbox on one side of the room with the SS unit on the other.
