Looks as though microsoft are updating there wifi adapter to 802.11n http://gizmodo.com/5359628/official-xbox-360-80211n-wi+fi-adapter-coming-soon god nows how much this one is going to cost but atleast with it not being built into the console they can update it.
This basically. There is coverage improvement, but the coverage of g is like 38m, so i highly doubt a lot of people if any have their 360 38metres away in a direct line from their router.
Even using N draft stuff I've had issues streaming HD content. Get a wire in there and job done! You do make a valid point though Nismo.
Bleh, wireless Haven't touched wireless since I discovered the joy of PLC adapters. Hate to think how much Microsoft are going to charge for this adapter given their track record of exorbitant peripheral costs.
