It would be good to be able to set the wireless region through the interface (especially during initial setup). Currently it appears only possible to set through the command line, meaning initial setup has to be done wired:
iw reg get (get wireless region)
iw reg set AU (set wireless region to e.g. Australia)
nano /etc/default/crda then set region to AU
Otherwise, it’s not always possible to see the correct SSID.
