Some cards can't handle ESSID = any; I don't know which ones, but I can now
make a guess :-)  You have to know the ESSID of the network you want to
use, and set that explicitly.

The reason a strange frequency is reported is that the card initially seems
to be on channel 0, and the table translating channels to frequencies
starts at 1.  My instance of the driver reports 42 GHz for channel 0 :-)
When the card associates with an access point, or in Ad-Hoc mode when you
set the channel explicitly, the frequency display will become reasonable.
