after factory reset /etc/config/wireless htmode is set to VHT80 in device section and there is also option for blockdfs in interface section.
Why dfs setting is in interfaces section not devices section?
How to pick channel 40 or 80MHz wide?
With standard factory settings i am able to pick only non-dfs channels and only 20Mhz wide.
Setting Dfs channel or wider channel results in access point with mac address all zeros and no wifi connectivity.
Do you mean setting in luci?
ok will try this from gui
