Are you using pump or dhclient.  I've seen it that sometimes one works
were the other doesn't.  Both ways around - on the same machine too.
Go figure.

Before switching if iwconfig(8) is telling you that you are connected
to the AP then trying running dhclient/pump by hand.  If you're using
dhclient (which I am) then run it my hand:
   # dhclient <iface-name>
It reports what it is doing and what it receives - this can help 
debug the problem.  Also look in the system logs (/var/log/syslog)
for any help messages there.  You should see PCMCIA log the insertion
of the card and what it trys to do.  - I am assuming that the PCMCIA
scheme your running does a DHCP lookup in /etc/pcmcia/network.opt.
