Broadcom does not support Linux at all. They give out no documentation of their chips & products and this results in no Linux drivers for broadcom wireless devices. This means that we must use a driver wrapper called ndiswrapper. It is a translator driver that makes a network card driver for MS Windows work on Linux.

Normally the progression of how drivers work looks like:
Linux kernel -> Linux network driver -> network card

With Ndiswrapper, it looks like:
Linux kenerl -> ndiswrapper -> Windows network driver -> network card

So now you see that it requires not 1 but 2 pieces, the ndiswrapper & the windows driver. Well, Knoppix versions from 3.8.x to currently 4.0.2 include ndiswrapper so this piece is already done for you. There is no need to download & compile/install it. So now all that is left is to get the windows driver piece to work. You can follow the generic ndsiwrapper installation instructions at http://ndiswrapper.sourceforge.net/m...Windows_driver and you can find Network card info listed alphabetically by manufacturer at http://ndiswrapper.sourceforge.net/m...dex.php/List#L
