Since Broadcom has not created drivers for my wireless network card (Linksys WMP54G) for Linux, my searching has led me to believe that I need to install and use ndiswrapper so that it may use the windows drivers.

After reading the instructions for this, I am lost at how to install it (which includes recompiling the Linux source). I'm a total Linux noob, and have no idea what to do. I've tried to follow the installation instructions, but I can't even find the Linux source, let alone figure out how to compile it.

Installation instructions are here: http://ndiswrapper.sourceforge.net/wiki/Installation

Any help?
