Hi,

thanks for the reply. I already use the latest regulatory db. If I set
the country to DE or EU, I do not get DFS-ETSI. Also it seems that the
driver stays with US when I use the modprobe config for cfg80211:
[ 2230.123217] cfg80211: Calling CRDA for country: EU

KHz), (N/A, 4000 mBm), (N/A)

When I use iw reg set DE this happens:

# iw reg get
country DE: DFS-UNSET
(2400 - 2483 @ 40), (N/A, 20)
(5150 - 5250 @ 80), (N/A, 20), NO-OUTDOOR
(5250 - 5350 @ 80), (N/A, 20), NO-OUTDOOR, DFS
(5470 - 5725 @ 160), (N/A, 26), DFS
(57000 - 66000 @ 2160), (N/A, 40)

Could it be that I need to change the EEPROM?

Thanks!
