18 is a recent addition; it's a variant of FCC that enables use in the
4.9G range (as you can see below).

Ok, something is b0rked; the 2432 and 2457 frequencies are obviously not
capable of 11a. As a workaround you can eliminate them from the channel
list using the chanlist directive; e.g.
ifconfig ath0 chanlist 1-4,6-9,11-255
should do it. That obviously won't work if you've got ap's on those
channels.
I will look into the problem.
