b43 is the new driver for wireless cards with Broadcom chipsets. People have had limited success up to this point. For now, search the Forum for “b43” to get the most up-to-date information.

b43 is a mac80211 driver, so it requires at least Aircrack-ng 1.0-beta2.

There is a patch by SuD which dramatically improves the injection speed, and makes the fragmentation attack work (Kernel or higher needed, compat-wireless-2.6 is supported using the 2.6.25-wl patches):

Also see this thread for more information.

To use the b43 driver, make sure you do:

 ifconfig wlan0 down
 iwconfig wlan0 mode monitor
 ifconfig wlan0 up

Or if you have iw installed:

 iw dev wlan0 interface add mon0 type monitor
 ifconfig mon0 up

This way, you can monitor on mon0 while still being associated on wlan0. (In the SVN version of Aircrack-ng, just use airmon-ng.)
