Note that this will have negative impact on roaming, but has never really caused me any real problems. I have found problems with several Wifi cards in "busy" locations, such as conferences and public places with multiple APs. iwn support N, but my experience has not been good. With a 'G' connection to my AP, I get about 20 Mbps, but when I turn on 'N', it drops to about 8 Mbps. I would not assume that 'N' is going to work better with the current software. -- R.
