Weird indeed, as...

regdbdump (2011-11-24):

country DE:
         (2400.000 - 2483.500 @ 40.000), (N/A, 20.00)
         (5150.000 - 5250.000 @ 40.000), (N/A, 20.00), NO-OUTDOOR
         (5250.000 - 5350.000 @ 40.000), (N/A, 20.00), NO-OUTDOOR, DFS
         (5470.000 - 5725.000 @ 40.000), (N/A, 26.98), DFS

At least the 5150 - 5250 MHz band (a few channels) should work. No idea 
what NO-OUTDOOR does, but it shouldn't kill beaconing, I guess.

Though, iw reg get says:

country 00:
         (2402 - 2472 @ 40), (6, 20)
         (2457 - 2482 @ 20), (6, 20), PASSIVE-SCAN, NO-IBSS
         (2474 - 2494 @ 20), (6, 20), NO-OFDM, PASSIVE-SCAN, NO-IBSS
         (5170 - 5250 @ 40), (6, 20), PASSIVE-SCAN, NO-IBSS
         (5735 - 5835 @ 40), (6, 20), PASSIVE-SCAN, NO-IBSS

which STILL is the world regulatory domain!

Setting iw reg set DE does nothing, but prints such a message in the 
Kernel log:

[37975.036703] cfg80211: Pending regulatory request, waiting for it to 
be processed...

It never returns something like "success" or even a message that the new 
regdomain has been set, and what regdomain exactly.

Also, querying the regdomain via iw reg get produces the same output 
(country 00 - world) as before.

This may also explain why forcing another regdomain doesn't work so well.

I suspect a Kernel bug somewhere, interesting.

Best regards,


Mihai
