What you mean by "a beacon for channel N+1". The AP is configured for channel N+1 and the STA probes for channel N right? Now if the AP sends a beacon on channel N, how does the STA know that it needs to associate on channel N+1? >> One other possibility is that the receiver is near to a very high >> powered AP and there is enough energy in the signal to recover it far >> from its transmitted channel.

This is again an interesting concept. Is this the case with all vendors? I guess with some of the 200mW APs it'll be more noticeable? How do STAs handle this? They get a beacon on channel 11 for an AP that is configured for channel 6. Can they associate on and start using channel 11? Puneet _______________________________________________ No banners.
