wrong driver dude
Hey dude, are you absolutly shore dat u r using the right driver??? I have also a broadcom 802.`11g card and I had a heck of a time until I realized that I was using the wrong darn driver. Go to a prompt and use lspci
and see what it gives you for a chipset, that's how I found out that I was wrong. Then mae sure that your using and L instaed of a 1 in the driver name cause the font in linux they look almost the same. bcmwL5.inf, haha.
aiht dude, keep in touch and I promise we'll get this working, I wrote this post using ndiswrapper wirelessly, so trust me, it works!!!
