They help provide a good counterpoint, thanks! Interesting that yours
don't list the pci path (as mine now do after the reset):
config wifi-device 'radio1'
option type 'mac80211'
option channel '36'
option hwmode '11na'
option path 'pci0000:00/0000:00:12.0'
option htmode 'HT40+'
list ht_capab 'SHORT-GI-40'
list ht_capab 'TX-STBC'
list ht_capab 'RX-STBC1'
list ht_capab 'DSSS_CCK-40'
option txpower '17'
option country 'FR'
