I'm not using the "fixed AP" method, and it doesn't seem that the
orinoco drivers support this, as I get "not supported" when I try to use
iwconfig eth1 ap <MAC address>.
What's happening is that I set an ESSID on the card, but it does not
actually switch to any base station with that ESSID, as shown by the
'iwconfig eth1' display of "Access Point".

The interface _is_ up in my tests. (ip link set dev eth1 up)
eth1 IEEE 802.11b ESSID:"dlab2" Nickname:"HERMES I"
Mode:Managed Frequency:2.437GHz Access Point: <MAC here>
Bit Rate:2Mb/s Sensitivity:1/3
Retry limit:4 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=21/92 Signal level=-46 dBm Noise level=-67 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:1
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Here, the MAC address shown by "Access Point" is NOT the MAC address of
the base station "dlab2". It is the MAC address of "vpnonly", which is
what the card comes up with when I stick it in. I cannot ever get the
display of "Access Point" to change using "iwconfig eth1 essid <xxx>".
This is my problem.
I performed further tests with the "vpnonly" base station, which is what
the card associates with all the time (despite my efforts to make it not
do so). When I unplug the base station's power, the card switches to
44:44:44... when any 'iwconfig' operation is done on it. If I then
(base station is still off) run "iwconfig eth1 essid rh-wireless", the
reported ESSID of the card (from iwconfig) shows "rh-wireless". If I
then turn the base station back on, the card associates with the _wrong_
base station after a slight delay (5-10s), and the ESSID and "Access
Point" are not matching/correct.

I currently do this exact operation.
