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 at 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
