FS#1133 - Can't set channels 12 and 13 on Raspberry Pi 3 in AP config

It is not possible to set up channel 12/13 on Raspberry Pi 3 in Wifi AP configuration. I get error “brcmfmac: brcmf_cfg80211_start_ap: Set Channel failed: chspec=4109, -20”.
Tested on 17.01.1 and latest snapshot (r5217-098afa1).
PS Raspbian works properly on 13 channel as AP.

I also have this problem (it is affected on internal Broadcom wireless card on Raspberry Pi 3 B and 3 B+). The country code setting in OpenWRT does not change the actual country code transmitted in Wireless signal as well as the limitation in each country. The only possible way to change the country code is to boot the latest Raspbian on the Raspberry Pi, use raspi-config to set the correct country code, and go back to OpenWRT.

David Xie commented on 07.08.2018 15:20

Please note that some countries forbid the use of Channel 12 and 13, and the country code issue is also prevalent in 5Ghz band on Raspberry Pi 3 B+.

Without setting the correct country code in Raspbian on Raspberry Pi 3 B+, the 5Ghz band won't even start in OpenWRT.

The BSSID info in my screenshots is omitted for privacy reason. Pay attention to the country code.
