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.

Most of my systems show the same, at least most of the time.


Any idea why this is happening?

don't know, may be regulatory.

After a reboot and an idle weekend, mine also look normal.
So, it's something transient it appears.

Err, I mis-spoke..the 9380 system still shows passive
scanning everywhere...

Busted one:

Bleh, seems my Sparklan 127 NIC is set to world-roam :(

What a total pain in the arse!

Its what the card was designed and programmed for. The only thing you
can do with world roaming cards then is just scan, and if you find a
beacon on a channel which is a non-DFS channel beaconing will be
enabled then.

Makes it basically useless as a 5Ghz AP though, eh?

Guess it's time to go find a hack to over-ride eeprom
settings :(
