Broadcom BCM4306 on Ubuntu Feisty Fawn
One thing that may not be obvious, even for seasoned Linux users, is that much less configuration is required with ndiswrapper on Feisty. If you're using a wireless laptop with Feisty, and like me, you've got a Broadcom bcm4306 card, you actually don't have to do much of anything to get wireless working with Feisty.
Simply install the package bcm43xx-fwcutter from your favorite package manager (synaptic, adept, or good ole apt-get or aptitude) and it will prompt you to download and install the firmware required for the Broadcom chipset. Once this install is complete, just reboot and the wireless chipset will connect without issue.
UPDATE



Just wanted to update everyone on bcm43xx-fwcutter. Because the boredlinks.googlepages.com/wl_apsta.o is no longer existent the setup is not automatic as it was before. Now you must download the driver yourself and extract the firmware and place it in your /lib/firmware folder.

Command:
sudo bcm43xx-fwcutter -w /lib/firmware ~/Desktop/bcmwl5.sys
