            Bug ID: 280718
           Summary: iwm(4): channel 13 vs. mode 11a
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New

The channel got stuck on 13 (despite channel - or channel -1 and mode was set
to 11a;  got me nowhere;  scan obviously did not return any;  couldn't get a
trace for probe/beacons while running around.

Similar to historic problem of roaming between 11g and 11a not working...?
