On the 5GHz band I have been using a channel option to skip some known bad channels (recurring radar activity and so on) in my previous place:
config wifi-device 'radio1' option type 'mac80211' option band '5g' option hwmode '11a' option path 'platform/soc/a800000.wifi' option htmode 'VHT80' option country 'DE' option txpower '13' option beacon_int '100' option cell_density '0' option channel 'auto' # option channels '52 132 149 165 36 100 116'
Rebuilding the setup from scratch on 22.03.3, to clear accumulated unused packages, I noticed that the scanning function would scan all channels at first (without the option above) and later only those selected (with the option enabled).
I half expected this keyword to influence the selection of usable channel but to have no effect on the scanning. Have I misunderstood the docs?
