I have a HP lappy with the IPW2200B/G chipset.  Basically you need to set the 
ESSID and the KEY *before* trying to bring up the interface.  So try it 
manually first:

sudo iwconfig eth0 essid <YOUR-ESSID>
sudo iwconfig eth0 key <YOUR-128bit-WEP-KEY>

Make sure "/etc/network/interfaces"  has a basic stanza for eth0:
...
iface eth0 inet dhcp
## No other options for eth0

Then "sudo ifup eth0".  You might see some info about DHCP etc and then your 
interface should be up and running.  Try pinging something:
ping www.google.com

If everything was successful, then you can automate all this by adding the 
values from the "iwconfig" commands above to the /etc/network/interfaces file 
and make eth0 automatically start at boot:

--- /etc/network/interfaces ---
# Start loopback and eth0 at boot
auto lo eth0

# Lopback config
iface lo inet loopback

# eth0 config - Wireless IPW2200 interface
iface eth0 inet dhcp
    # My Office
    wireless-essid      <YOUR-ESSID>
    wireless-key        <YOUR-128bit-WEP-KEY>

--- END OF FILE ---

There's probably some hotplug stuff in there too, but I left it out for 
simplicity ;)

Have a read of "man iwconfig" and "man wireless".  Other good reading is "man 
5 interfaces" (section 5 is file formats).

Good luck :)
