The proprietary Broadcom wireless LAN driver (wl, aka broadcom-sta) provides support for some Broadcom-based PCI/PCIe hardware. It includes a binary-only component targeted for the x86 or x86-64 architecture. Supported devices are listed at the end of this page.

The driver depends on the x86 or x86-64 architecture (Debian i386 and AMD64 ports respectively).

{i} The BCM4313, BCM43224 and BCM43225 chips are alternatively supported by the brcmsmac driver. The BCM4311 and BCM4312 chips are alternatively supported by the b43 driver.

{i} As of Debian 7 “Wheezy”, the BCM4321 and BCM4322 chips are alternatively supported by the b43 driver.

Installation

Debian 7 “Wheezy”

Add a “non-free” component to /etc/apt/sources.list, for example:
# Debian 7 “Wheezy”
deb http://http.debian.net/debian/ wheezy main contrib non-free
Update the list of available packages. Install the relevant linux-headers and broadcom-sta-dkms packages:
# apt-get update
# apt-get install linux-headers-$(uname -r|sed ‘s,[^-]*-[^-]*-,,’) broadcom-sta-dkms
This will also install the recommended wireless-tools package. DKMS will build the wl module for your system.
Unload conflicting modules:
# modprobe -r b44 b43 b43legacy ssb brcmsmac
Load the wl module:
# modprobe wl
Configure your wireless interface as appropriate. See also known issues.

Debian 6.0 “Squeeze”
Add a “non-free” component to /etc/apt/sources.list, for example:
# Debian 6.0 “Squeeze”
deb http://http.debian.net/debian/ squeeze main contrib non-free
Update the list of available packages. Install the module-assistant and wireless-tools packages:
# apt-get update
# apt-get install module-assistant wireless-tools
Build and install a broadcom-sta-modules-* package for your system, using Module-Assistant:
# m-a a-i broadcom-sta
Blacklist the brcm80211 module, to prevent it conflicting for support of BCM4313, BCM43224 and BCM43225 devices:
# echo blacklist brcm80211 >> /etc/modprobe.d/broadcom-sta-common.conf
Rebuild your initial ramdisk, to blacklist modules defined at /etc/modprobe.d/broadcom-sta-common.conf within initramfs:
# update-initramfs -u -k $(uname -r)
Unload conflicting modules:
# modprobe -r b44 b43 b43legacy ssb brcm80211
Load the wl module:
# modprobe wl
Configure your wireless interface as appropriate. See also known issues.

Known Issues

The Sonics Silicon Backplane driver (ssb) conflicts with the wl driver (545388).
b44, b43, b43legacy and ssb are blacklisted by default as of broadcom-sta 5.10.91.9.3-3 (brcm80211 and brcmsmac since 5.100.82.38-1, 5.100.82.38-2 respectively).
This prevents use of any Ethernet device supported by b44.
Frequent disconnections can be experienced. This may be resolved by disabling power management via:
iwconfig(8) (e.g. iwconfig eth1 power off)
laptop-mode-tools: set WIRELESS_BATT_POWER_SAVING=0 within /etc/laptop-mode/conf.d/wireless-power.conf
Monitor mode is not supported prior to driver version 5.100.82.111.
Debian 7 “Wheezy” users, see /usr/share/doc/broadcom-sta-{dkms,source}/README.txt.gz to enable.
Wireless channels 12 and 13 are not available for use (636119).
Inability to join networks with hidden SSIDs (698697).
Upgrading from Debian 6.0 “Squeeze” to Debian 7 “Wheezy” may require network configuration amendment (648396).
See bugs reported on broadcom-sta.
