Welcome to LQ!
Before helping you, can I suggest that in future:
1. Please try to post what distro and version of Linux you're using
2. Please be clear
about what you're trying to do; and what is not working - here I had to Google to figure out that you're trying to install a driver for your WLAN card?
2. You'll notice that in this forum members try to assist people in a way where you'll learn how to do something - this is definitely not the place for a step by step guide from which you cut and paste commands.
Getting to your question; please check this link out: http://www.planex.net/pdf/wireless/G...x_v1.1_Eng.pdf
Hope this helps you
This is a very interesting pdf that will give you a guide to building and installing the driver.
