Is any of the above the AP you are looking for? (i.e. right bssid).

Strange, why would a broadcast SSID scan turn up less BSSes? Can you make=
=20
sure you have the dev.iwi.0.antenna sysctl set to "0"?

iwicontrol? That's no longer useful. If you really have

you should have removed net/iwi-firmware and replaced it with=20
net/iwi-firmware-kmod as stated in UPDATING.

I reproduced your setup with a Linksys-54abg and a 2915ABG running a=20
recent RELENG_6. Works like a charm - see attached.

If you do have firmware-iwi-kmod and things are still not working properly=
=20
you should try the following:
1) Disable WPA on AP and see if you can attach w/o wpa_supplicant
2) See if you can attach w/ wpa_supplicant (key_mgmt=3DNONE)
etc. ... to find out which part really is the culprit. Then you should=20
set "sysctl debug.iwi=3D5" and check console output for problems. Let me=20
know how it goes.
