Autogenerated wifi configuration results in:

  * inability to set frequency in LUCI

  * channel analysis in LUCI shows only radio0 with incorrect frequency (radio0 is 2.4GHz, channel analysis shows chart for 5GHz)

  * iwinfo returns results only for 'iwinfo radio0 ...', but results are taken from  phy1 (which belongs to radio1)

        option htmode 'VHT80'
        option disabled '1'


Enabling radios and editing files manually  gives working configuration.

** Workaround **
Removing path and forcing correct phys makes luci/iwinfo happy.

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '11'
