Comment (by moonman):

 Sorry about the log being squiched into one line. I used my phone to post
 the msg while away from home.

 Here's the same log:

 Here's /etc/config/wireless :
 {{{
 config wifi-device 'radio0'
         option type 'mac80211'
         option channel '11'
         option hwmode '11g'
         option path 'pci0000:00/0000:00:01.0/0000:01:00.0'
         option txpower '20'
         option htmode 'HT40'
         option noscan '1'
         option country 'CA'

 config wifi-iface
         option device 'radio0'
         option network 'lan'

         option ssid 'Ira-5GHz'

 }}}

 The strange thing is: I fiddled for hours before using LuCi ''and''
 modified /etc/config/wireless by hand and nothing would bring the
 interface up. It would error out and go into ''Client'' mode. After
 leaving it for 3 days because I was away, I came back to it today and
 noticed and extra "config wifi-iface" for ''radio1'' under
 /etc/config/wireless and removed it. It ''works'' now, however something
 is still off since it does not work for anyone out of the box, or after
 using LuCi to set it up with the above messages in logs.
