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?

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?
