As far as getting drivers for a wireless card, I
highly recommend
linuxant. They have the driver-loader for any wireless cards. It is really easy to set up and once it's setup and installed, you shouldn't ever have to mess with it again. Just use the internet.
Linux and charges a one-time fee of $20 for the software. There's also a free 30 day trial so you can make sure it works first. Some people have a fundamental difference with the software because it costs money, but personally, I don't care. I value a working Linux desktop much more than twenty bucks.
When you get to the page, click on
"DriverLoader for Wireless LAN Devices". At the next page, you're going to need to know what your chipset for your wireless card is. (I googled my card and found the info). Once you know what chipset you're using, you can check the list to make sure it's there. (It will be). Then you just click on
"Download" on the left side of the screen. Then click
"I agree" on the agreement page. On the next page, you will need to click
"DirverLoader Download page" located in the text, near the top. Then select your distribution. Then you download the correct DriverLoader for your kernel.
IT IS IMPORTANT TO KNOW WHAT KERNEL VERSION YOU HAVE. This can be figured out by opening Konsole and typing:
Hope it helps
