I did a bit more testing, I have to admit that I am not well versed in wifi internals.
1. ifconfig wlan0 list aps shows my aps having rate 54M (Im not entirely sure what this means).
But however when I connect to it, it shows up as 11g
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

2. Adding mode 11a to rc.conf didn't change anything. Still connects to 2.4Ghz band.
3. ifconfing wlan0 scan still doesn't show my 5Ghz only APs (at least some I tested)
Also, what does 11a mean? shouldn't it be 11n?
