Ok, sysctl dev.iwn.0.debug=0x1, wlandebug +scan, and then start wpa_supplicant.
It should be reasonably obvious what's going on - if it can't see APs
or it can't transmit anything successfully, then at least I know where
to begin looking when I have spare time.
I have a 5100 in my T400:
iwn0@pci0:3:0:0: class=0x028000 card=0x12118086 chip=0x42378086
rev=0x00 hdr=0x00
vendor = 'Intel Corporation'
device = 'PRO/Wireless 5100 AGN [Shiloh] Network Connection'
class = network
