Installing Broadcom 4306 (43XX) Drivers in Ubuntu

By default, the Broadcom 4306 drivers (which are found in the Acer Ferrari 3000 laptop) are not installed with Ubuntu 9.04. After a fresh install, connect the system to the internet via an Ethernet cable, and run:

sudo apt-get install b43-fwcutter

then reboot the system.

The wireless adapter should now be working properly.
