Hi James,

The link I provided will tell you how to find out. 
https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported

The quickest way involves using a cli command, lspci.

E.g.

:~$ lspci | grep Network
01:0a.0 Network controller: Broadcom Corporation BCM4306 802.11b/g
Wireless LAN Controller (rev 03)

If you see something like the above then you have a Broadcom card and
need to download some firmware to get it working. So if you're on Ubuntu
7.10, then you should be able to install it in the System ->
Administration -> Restricted Drivers Manager, with a wired connection. 

There is a wiki page about this at

Steve
