Does anyone else get an issue playing wi-fi games? I haven't tried any other games on wi-fi, but Call of Duty World at War lags when you play on wi-fi through the USB loader. Single player and everything else is speedy and works great, however it lags on wi-fi. It's not my internet's fault either, I have the original disk and it works just fine on wi-fi with no lag or anything. It especially starts lagging me if I'm host, but the other people in the game don't lag even if I'm host and I'm lagging. Any ideas?
