b43 is a driver for the Broadcom 43xx series wireless devices.
|
||
|
|
|
||
|
|
Check "lspci" for something like
|
||
|
|
"Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
|
||
|
|
to determine whether you own such a device.
|
||
|
|
|
||
|
|
This driver supports the new BCM43xx IEEE 802.11G devices, but not
|
||
|
|
the old IEEE 802.11B devices. Old devices are supported by
|
||
|
|
the b43legacy driver.
|
||
|
|
Note that this has nothing to do with the standard that your AccessPoint
|
||
|
|
supports (A, B, G or a combination).
|
||
|
|
IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
|
||
|
|
|
||
|
|
It is safe to include both b43 and b43legacy as the underlying glue
|
||
|
|
layer will automatically load the correct version for your device.
|
||
|
|
|
||
|
|
This driver uses V4 firmware, which must be installed separately using
|
||
|
|
b43-fwcutter.
|
||
|
|
|
||
|
|
This driver can be built as a module (recommended) that will be called "b43".
|
||
|
|
If unsure, say M.

This adds additional runtime sanity checks and statistics to the driver.
|
||
|
|
These checks and statistics might be expensive and hurt the runtime
|
||
|
|
performance of your system.
|
||
|
|
This also adds the b43 debugfs interface.
|
||
|
|
|
||
|
|
Do not enable this, unless you are debugging the driver.
|
||
|
|
|
||
|
|
Say N, if you are a distributor or user building a release kernel
|
||
|
|
for production use.
|

|
|
Only say Y, if you are debugging a problem in the b43 driver sourcecode.
