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 :)
