I setup the new Airport Extreme to run an 802.11n-only network using the 5Ghz frequency. In OS X, the two C2D MacBook Pros in the house have no problems connecting to this network. They get 300 Mb each time and the whole thing really rocks. In Boot Camp (XP SP2), the same MacBook Pros can see the new 802.11n 5GHz Airport Extreme network, but get a really generic "can't connect to network" error when trying to connect. I was wondering if anyone else had run into this and if they had any advice. Thanks!
