I have got a live disc version of Mandriva Linux, and also Slackware Linux, but I do not know which Drivers I need to get them to work with wireless??!!

I am using a HP Compaq with an AMD Turion 64 x2 processor, and a Broadcom wireless card.

Can anyone help?! :]

thanks!

Which brands of wireless cards offer open source drivers for them?

I ASSUME Intel and Atheros do, while the others do not (Broadcom, Realtek, etc). Can anybody confirm this?
I know they don’t need to be open source for them to work, but I’m pretty sure Broadcom is closed source and not only that, they’re very piss poor quality. I’m sure if they were open source, community developers would jump on the code to improve on them. I’m just curious which companies ARE open source because I want to support them by buying their products instead of closed source companies.

Ok so I’m pretty decent with computers but a complete newbie when it comes to linux. The situation this guy has in the link below is exactly my problem (even the same laptop) but i dont really understand his solution lol. so if you could kind of dumb it down and explain it to me in a more newbie-friendly way it would be greatly appreciated and of course 10 pts. There are only 3 steps.

Oh and if it matters at all, i have a dual boot with vista (obviously my wireless card works fine on vista) Thanks a lot!
