The old website for now has a copy of the old content:

b43 and b43legacy are wireless drivers for Broadcom SoftMAC chipsets. Kernel will automatically pick a proper module for you:

  • b43 for any new (supported) hardware
  • b43legacy for BCM4301 and early BCM4306 versions


  • You need to have firmware files (usually in /lib/firmware/) so b43(legacy) can upload them to the card and run properly.

List of hardware

To check for a present hardware model execute following command:

lspci -nn -d 14e4:

Please look carefully at device ID and chipset name.
