Support for 10.04 desktop ends in April of this year, and much has changed in those 3 years since it was released. I'd suggest you download the iso for 12.04 (available here), and install that.
What you have to keep in mind that drivers for most devices, except those on the very bleeding edge, are included with the kernel package, and unless they are closed source, aren't available as a separate package. Intel has been very good in supporting open source, so by installing the current LTS release, the drivers will more than likely be automagically installed for you.
Actually after writing the above, I did some research, and it seems your device should work with Lucid. I'd suggest you boot from the Live CD, and once at the desktop, open a terminal, and type the following command:
what the command does is create a text file with a listing of you network hardware similar to this:
sudo lshw -C network > network.txt
I don't have a wireless device on this system, but you should see your wired and wireless devices in the output.
sudo lshw -C network
