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.
for me channels 36,40,44,48 are ok in 5ghz. used the latest wireless-testing just brought the card up as station mode.
Any idea why this is happening?
don't know, may be regulatory.
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...
