I think stable@ is probably the best choice. wireless@ would also be
an appropriate place.

I don't see any real issue with your configuration, but I do see
something odd and it may be tied to the problem you are seeing. FWIW,
I also have an agn iwn card, but I only have a G access point at this
time and it runs fine in G.
The oddity is that you specify your ssid in the rc.conf file while
using WPA. I've never seen that before. It's in my wpa_supplicant.conf
file. It seems more reasonable for a laptop that may need to associate
with a home and a work SSID as well as ones at conferences and, in my
case alternate work and home SSIDs. When it is in the rc.conf file, it
requires change with every relocation.
in any case, you might try moving the SID into the wpa_supplicant.conf
file, but my bet is it is N specific. Paging Adrian.
