Thanks Grant and other users for your posts on getting WIFI to work.

I have an HP Notebook ze5600ca with built in WIFI and WinXP Home. I was able to get the WIFI working with help from your posts.
I found the name and location of the Windows WIFI driver in WinXP, then I started up Knoppix and clicked on the Penquin icon at the bottom left of the screen and ran ndiswrapper and pointed it to the Window driver location.
I then ran the WLAN program, also from the Penquin location and I just chose all the default values.

I am not too sure if the next step is necessary but to get the WIFI functioning for this session I had to go to the network card confiquration program and run it. I didn't think I had to do that the previous session?

This got my Notebook to connect with a neighbours WIFI which apparently is not locked down.
