This is fairly easy with Ubuntu 7.10 and later. This assumes you have your notebook set up to dual-boot both Ubuntu and Windows.
- Get the directory from your Windows installation that contains the device driver for WiFi. Copy that directory to your home directory in Linux.
- From the command line, enter ‘sudo apt-get install b43-fwcutter’ (or search for that package in Synaptic and install it).
- During the install, you will be asked if fwcutter can extract the microcode for your WiFi. Answer yes.
- Your WiFi should now work.
