Welcome to easylinuxwifi.org, home of the Auto-NDISwrapper project. Where we try to make Linux wifi a little bit more painless. Some hardware manufacturers do not provide linux drivers for their products nor provide the hardware specifications necessary for creating them.
A project called NDISwrapper was created so that these cards could be used in Linux using Windows drivers. Sometimes finding and installing these drivers can be difficult, and that's when Auto-NDISwrapper comes into play.
