(1) ifconifg wlan0 will tell you the "parent interface:" but the pciconf line
you posted says iwm0 was attached.

(2) thanks

(3) "Greenfield" mode -- I don't know how they may call it;  In the config for
the radio is there some "compatibility" which says "11n only" or something like
that (instead of "11g/n" or "auto")?
Alternatively we could go and have a look at the beacon using tcpdump;  would
be bit 5 (or bit 4 if counted from 0) in the HT Capabilities Info field; 
though I am pretty sure wireshark would decode it correctly.
Otherwise can you ssh into your AP and check what it logs for auth_failures in
/var/log/messages (I think that's where it was but don't nail me down on it).
So far this is a shot in the dark from me and it could be something entirely
different.  Hard to find Sampo remotely like this ;-)
If you want I can help getting packet traces and full logs (in private) and we
can have a look.
