Hi, Well, if you don't assign a channel, the net80211 scan module will scan the channels, find the channel with the lowest noise floor as reported by the driver and use that. Now, ideally it'd actually check the channel for interference and channel busy status, and use _that_ metric. So, if someone wants a mini-project to implement that, I'd be happy to guide them / help them get that working. On ath(4), of course. -adrian
