Unable to use wi-fi on Ubuntu Hoary under WEP

I have the same card in my laptop, and it works fine there. Because I have
to use different wireless settings at home and at work, I do the connection
via script files. Try this to see if this will work for you:

Breezy should recognize your card and start the corresponding module
automatically. To check, open a terminal and type


the response should show your card configured as ra0. If so, type:

sudo iwconfig ra0 essid "your airport ESSID"

sudo iwconfig ra0 key "your WEP key here"

(the WEP key should be entered just as it was entered in the Airport setup)

if your airport is set up as a DHCP server, type

sudo dhclient ra0

If that sequence works, then just enter the ESSID and the WEP key in the
Network Settings application. make sure that if you set your Airport to use
a hexadecimal key, you select the same type of key in the interface
properties dialog, and that DHCP is selected.

Or ... you can just put all the series of commands that worked into a script
file, and just execute it when you want the network on.
