I had a similar problem w/ a 4309.
If you haven't solved this already, please check that the radio is
actually enabled. some laptops have a button. some have a key sequence.
many also have a BIOS setting. mine looked pretty much the same as yours
to FreeBSD but just endlessly scanned the channels for a signal until i
noticed that the radio was disabled in BIOS.
