Pleae note that the b43legacy driver requires "version 3" firmware,
|
|
|
77baa27 |
while the b43 driver requires "version 4" firmware.

Once you have obtained the source of the appropriate firmware,
|
|
|
77baa27 |
run the command below as root. Be sure to replace '<DRIVERFILE>'
|
|
|
77baa27 |
with the actual name of the source file (e.g. wl_apsta.o):
|
|
|
77baa27 |
|
|
|
77baa27 |
b43-fwcutter -w /lib/firmware <DRIVERFILE>
|
|
|
77baa27 |
|
|
|
77baa27 |
The command above will extract the firmware to the appropriate location
|
|
|
77baa27 |
for loading by the driver as necessary.
