I can't be sure, since different drivers behave differently, and I have
no experience with the Orinoco / Hermes, but generally, this means that
the card isn't associated with the AP. When it is, you should see
"Acess Point: xx:xx:xx:xx:xx:xx", with the hex digits of the AP's
address.
We need to figure out why the card isn't associating. Are you using
WEP/WPA?

ifconfig doesn't matter here, since the problem is with the wireless
association.
