I've searched through the forums to find several guides to setting up the broadcom wireless card (4311 rev02) on my computer, but I'm using the LiveCD for now. I don't want to install Ubuntu on this computer if i can't use the built-in wireless card.
If I follow the HOWTO correctly, should I see results if I'm using the LiveCD or will I not be able to do this until I fully install Ubuntu?

This is the HowTo I was following:

I'm running 8.04, but I've read that this should still work.
Any thoughts?
