Did your wireless network card come with your laptop? If so, then you might want to check out <http://www.linuxlaptops.com> and click on Laptops&Notebooks. Someone might have posted some info there that could possibly help you to configure your wireless network card.

A few minutes ago, I posted a reply to "Wireless card not recognized" with similar information. You might want to check it out--specifically the part where I did some research to find out which driver is used in XP. It will be something like *.SYS. You can get that information either via the web or via the Control Pannel in XP. After you know what the name of the driver is, then you'll need to find the correct .INF file (and possibly a few other files). I did that for my own setup via the 2 find statements. Don't be alarmed if everything doesn't work for you the first time around--it didn't work for me the first time either. Actually, it took me a series of trials and errors to hack together my setup. (I could have done it much quicker had I downloaded the driver from the ndiswrapper website, but that would have failed with my setup--it's a long story.) A laconic version of that story is that I was running Knoppix via a livecd, and I insisted upon working with the XP drivers (just because I heard it was possible).

Anyway, this should be enough to at least help you get started. By the way, if knoppix also has an issue with your wired netword card, then you can do something similar to get it working.
