Ok, here is the issue. I have a wireless router downstairs, it connects wireless to another wireless router, making it a bridge (DD-WRT WRT54G for both of them). On this bridge, I have a couple connections, but two in particular. An XBOX 360 and an computer running Windows. When this computer is on, when I try to play XBOX 360, there is a ton of lag spikes and it basically makes the game unplayable. Literally, once I turn the PC off, the lag spikes stop. I've tried two seperate computers on this as well. I've netstat'd the PC and I've seen no odd packets or anything. Anybody have any ideas?
