Here's my exact script to that I use to get the card working with comments (the best I know how to describe what each step does).
#! /bin/sh
#these first three lines get the green light on
modprobe pcmcia_core
modprobe yenta_socket
modprobe ds
#this line gets the green light blinking
#you have to successfully compile the driver from
www.admtek.com
#for this to be successful
insmod /usr/local/bin/ADM8211/8211.o
#need a brief pause before trying to configure the card
sleep 3
#these are universal card settings by default
iwconfig eth1 channel 6 rate 11M
#thest are my personal settings for a DSL connection, but yours
#should be similar. I use a static IP. Never could get DHCP #working
iwconfig eth1 essid [insert your essid]
iwconfig eth1 key [insert your key]
sleep 1
ifconfig eth1 [insert your IP]
route add default gw [insert your default gw
#--------------------------------------------------------------------
once you have it to where you think it should work try pinging yoruself (127.0.0.1), trying pinging other machines in your network, try pinging your default gw, and finally, try pining sites outside your network.
