I am trying to use Knoppix on a laptop with a BCM4318 wireless card. Output from lspci -nn | grep BCM:
05:02.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

According to http://linuxwireless.org/en/users/Drivers/b43, this card is supported by b43. And
http://www.knoppix.net/forum/threads...dapter-problem says that I can install the firmware and comment out the blacklist for b43.

This however, does not work. I think it is because there is no b43 module included. If I manually do "sudo modprobe b43", I get
FATAL: Module b43 not found.

In /lib/modules/3.0.4/kernel/drivers/net/wireless, there is b43legacy but not b43.

How do I add the b43 module?
