Subject: ath9k  9380:  All 5Ghz channels flagged as passive-scanning
Date: Fri, 20 May 2011 15:22:45 -0700	[thread overview]
Message-ID: <4DD6E9B5.3020905@candelatech.com> (raw)

This is on 2.6.39-wl+

All the 5Ghz channels are showing as passive scanning, which
makes them unusable for APs if nothing else.

Any idea why this is happening?

On a previous boot, I had an STA associated on channel
40 and that was the single 5Ghz channel that didn't
show 'passive scanning'.  I removed it's configuration
so that it wouldn't associate and upon reboot I see
the output below.

More than happy to provide more details...
