Rich,

I got my wireless card to work on my laptop. I had to do some searching
around to in the Ubuntu Forums, and I ended up having to download an
updated driver/firmware for my Broadcom BCM4318 wireless adapter. I also
had to install ndiswrapper. Have you tried using ndiswrapper? I don't
remember if we talked about this.

At today's Ubuntu Live Conference, I attended a presenation about Laptop
support for Ubuntu. Matthew Garrett gave an excellent presentation of
all the numerous issues Ubuntu (and other Linux distros) have supporting
laptops. Much of it seems very much hardware related. After his
presentation, he helped me troubleshoot my problem. He was very helpful.

BTW, he is moving out here to Portland (from the UK) after he graduates
college. I'm hoping he will get active in PLUG when he arrives!
