MW2 lags hard-wired or not. It is because of the lack of dedicated servers that you get lag, not wireless vs wired.If you are using it for COD or other first person shooters, I would just hardwire it. The lag will cause you to miss a kill too many times.
Ive got one on a 3RR launch console. I may end up buying another 360. Do the new "slims" come wireles ready?
looks like they do pm me, Ill try to get on this weekend but rarely am on the net on the weekends
Slims come with wireless N built in.
