May be more to this than just missing 802.11a channel reporting...
walked to within range of a NetGear dual-band 802.11N 5GHz/11G 2.4GHz AP
and could not even see the 802.11A side of the AP, (while another
machine was associated with it, so both halves of the AP were up).
I associated on the G channel, then tried to force an association on the
A channel by setting the frequency with iwconfig. At some point, I got
the following (note that I could still associate with the G channel when
done):
