my wireless card uses a different chipset so I can't give you a step by step, untar the driver, open up File Browser and goto the directory you untar'd it into and look for an INSTALL or README file, open it up with a text editor and just follow the instructions. Also I found a thread that gives step by step instructions:
http://www.linuxquestions.org/questi...k+2500+install
always search before you ask a question, 95% of the time you will be able to find what you need.
linux is difficult at first but once you start to understand it there is nothing better if you like to tinker, windows is just too boring for me.
good luck.
