Broadcom 4313, 43224, 43225 devices (brcm80211)
This page describes how to enable support for WiFi devices based on Broadcom BCM4313, BCM43224, BCM43225 chipsets on Debian systems.
Contents
brcm80211 is a free and open source mac80211 driver currently in development, supporting specific Broadcom 802.11n/g PCIe wireless LAN chipsets:
- BCM4313 (PCI-ID: 14E4:4727)
- BCM43224 (PCI-ID: 14E4:4353)
- BCM43225 (PCI-ID: 14E4:4357)
It is included in Debian Linux kernel images since linux-2.6 2.6.32-22. Non-free firmware is required and must be installed prior to device operation.
This staging driver is only available for the x86 and x86-64 architectures (Debian i386 and AMD64 ports respectively) at this time.
For support of other Broadcom PCI wireless LAN chipsets, see bcm43xx.
Installation
Lenny
Install the subversion and wireless-tools packages:
# aptitude install subversion wireless-tools # exit
Acquire and install device firmware:
$ svn export svn://svn.debian.org/svn/kernel/dists/trunk/firmware-nonfree/brcm80211/brcm $ su # mkdir /usr/local/lib/firmware # cp -r brcm /usr/local/lib/firmware # cd /usr/local/lib/firmware/brcm # ln -s bcm43xx-0-610-809-0.fw bcm43xx-0.fw # ln -s bcm43xx_hdr-0-610-809-0.fw bcm43xx_hdr-0.fw
Add the Debian Backports repository to /etc/apt/sources.list, for example:
# Backported packages for Debian Lenny deb http://backports.debian.org/debian-backports lenny-backports main
Update the list of available packages and install a Linux 2.6.32 kernel image appropriate for your system. For example:
# aptitude update # aptitude -t lenny-backports install linux-image-2.6-$(uname -r | sed 's,.*-,,')
- Restart your system and boot with the newly installed kernel.
The necessary kernel module should be automatically loaded. If necessary, it can be manually loaded via:
$ su # modprobe brcm80211
Verify your device has an available interface:
# iwconfig
Configure your wireless interface as appropriate.
Squeeze
Install the subversion and wireless-tools packages:
# aptitude update && aptitude install subversion wireless-tools # exit
Acquire and install device firmware:
$ svn export svn://svn.debian.org/svn/kernel/dists/trunk/firmware-nonfree/brcm80211/brcm $ su # mkdir /usr/local/lib/firmware # cp -r brcm /usr/local/lib/firmware # cd /usr/local/lib/firmware/brcm # ln -s bcm43xx-0-610-809-0.fw bcm43xx-0.fw # ln -s bcm43xx_hdr-0-610-809-0.fw bcm43xx_hdr-0.fw
As the driver may already be loaded, reinsert the module to access installed firmware:
# modprobe -r brcm80211 ; modprobe brcm80211
Verify your device has an available interface:
# iwconfig
Configure your wireless interface as appropriate.
