Broadcom 43xx wireless devices
This page describes how to install and configure WiFi devices based on Broadcom 4303, 4306, 4309, 4311, 4312 and 4318 wireless chipsets.
?TableOfContents(3)
Device Identification
The page ["HowToIdentifyADevice/PCI"] explains how to identify a PCI device. For example:
update-pciids lspci -nn
You should see your Broadcom Device
0c:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN [14E4:4311] (rev 01) or 0c:00.0 Network controller: Broadcom Corporation Dell Wireless 1390 WLAN Mini-PCI Card (rev 01)
The [:HowToIdentifyADevice/PCI#pci-id:PCI-Id] isn't sufficient to determine the Broadcom chipset within. The relevant driver has built-in logic to probe the actual chipset.
Drivers
There are multiple drivers supporting Broadcom wireless LAN chipsets.
Linux native drivers:
[#bcm43xx bcm43xx] driver ([http://bcm43xx.berlios.de/?go=devices supported devices])
- included in mainline kernels from 2.6.17-rc2
- disabled in Debian 2.6.24 and later kernels
- driver was removed from the mainline kernel in 2.6.26
[#b43 b43] driver ([http://wireless.kernel.org/en/users/Drivers/b43#supported supported devices])
- the new driver for modern 802.11g and 802.11a chipsets
- introduced in kernel 2.6.24
[#b43_legacy b43legacy] driver ([http://wireless.kernel.org/en/users/Drivers/b43#supported supported devices])
- for legacy 802.11b-only devices and the BCM4306 revision 2 chipset
- introduced in kernel 2.6.24
The bcm43xx driver is no longer developed. More information on the b43/b43legacy drivers can be found on the Linux Wireless [http://wireless.kernel.org/en/users/Drivers/b43#b43andb43legacy b43 driver page]. Note that none of the above drivers support USB devices based on Broadcom wireless chipsets.
Using Windows' binary drivers:
- [#ndiswrapper NDISwrapper] plus the relevant Windows NDIS driver. This is a workaround for devices not supported natively by Linux, such as USB devices based on Broadcom wireless chipsets.
?Anchor(bcm43xx)
Native bcm43xx driver (Etch with 2.6.18 kernel only)
For kernels earlier than 2.6.24. This is included as a module in Debian kernel images. The bcm43xx driver requires firmware which must be downloaded separately (can be performed by the etch-volatile/bcm43xx-fwcutter package during installation).
- You are required to install the etch-volatile/bcm43xx-fwcutter package from the [:DebianVolatile:Debian Volatile] repository due to bug 437488. Installing the etch/bcm43xx-fwcutter package will fail to download firmware if requested.
1. Add the Debian Volatile repository (including the "contrib" section) to your /etc/apt/sources.list file, for example:
# Debian Volatile (Etch) deb http://volatile.debian.org/debian-volatile etch/volatile main contrib non-free
2. Update the list of available packages and install the etch-volatile/bcm43xx-fwcutter and etch/wireless-tools packages:
aptitude update aptitude install bcm43xx-fwcutter wireless-tools
If you have an Internet connection available, allow the etch-volatile/bcm43xx-fwcutter package to fetch and extract firmware.
3. Load the bcm43xx module:
modprobe bcm43xx
4. Verify your device now has an available interface:
iwconfig
5. Raise the interface to activate the radio, for example:
ifconfig eth1 up
6. [:WiFi/HowToUse:Configure] your wireless interface as appropriate.
?Anchor(bcm43xx_troubleshoot)
Troubleshooting
- Examine the kernel ring buffer (dmesg) to verify the required firmware files are being loaded by the driver. Lack of firmware is the usual reason for the "SIOCSIFFLAGS: No such file or directory" error message.
Ensure that you have installed the etch-volatile/bcm43xx-fwcutter package from [:DebianVolatile:Debian Volatile].
- Run "dpkg-reconfigure -plow bcm43xx-fwcutter" to fetch and extract firmware again. Firmware will only be fetched if not already present in the /lib/firmware directory on your system.
- Your device may be detected (or better supported) through the b43 or b43legacy drivers. Install an etchnhalf kernel image ("apt-cache search linux-image-2.6.24-etchnhalf" and install one appropriate for your system), restart your system to boot using this kernel, then follow the [#b43 b43] or [#b43_legacy b43legacy] driver procedures below.
?Anchor(b43)
Native b43 driver
For 2.6.24 and later kernels with modern Broadcom 802.11g wireless chipsets. This is included as a module in Debian kernel images. 802.11b-only devices and BCM4306 revision 2 chipsets are supported by the [#b43_legacy b43legacy] driver instead. The b43 driver requires version 4 firmware which must be downloaded separately (can be performed by the b43-fwcutter package during installation).
1. Add a "contrib" section to your /etc/apt/sources.list file, for example:
deb http://ftp.us.debian.org/debian lenny main contrib non-free
2. Install the b43-fwcutter and wireless-tools packages:
aptitude update aptitude install b43-fwcutter wireless-tools
If you have an Internet connection available, allow the b43-fwcutter package to fetch and extract firmware.
3. Load the b43 module:
modprobe b43
4. Verify your device now has an available interface:
iwconfig
5. Raise the interface to activate the radio, for example:
ifconfig wlan0 up
6. [:WiFi/HowToUse:Configure] your wireless interface as appropriate.
Troubleshooting
- Examine the kernel ring buffer (dmesg) to verify the required firmware files are being loaded by the driver. Lack of firmware is the usual reason for the "SIOCSIFFLAGS: No such file or directory" error message.
- Run "dpkg-reconfigure -plow b43-fwcutter" to fetch and extract firmware again. Firmware will only be fetched if not already present in the /lib/firmware/[b43|b43legacy] directories on your system.
If necessary, firmware can be manually acquired and extracted using the b43-fwcutter utility, see http://wireless.kernel.org/en/users/Drivers/b43#firmwareinstallation
?Anchor(b43_legacy)
Native b43legacy driver
For 2.6.24 and later kernels with 802.11b-only devices or BCM4306 revision 2 chipsets. This is included as a module in Debian kernel images. Modern Broadcom 802.11g wireless chipsets are supported by the [#b43 b43] driver instead. The b43legacy driver requires version 3 firmware which must be downloaded separately (can be performed by the b43-fwcutter package during installation).
1. Add a "contrib" section to your /etc/apt/sources.list file, for example:
deb http://ftp.us.debian.org/debian lenny main contrib non-free
2. Install the b43-fwcutter and wireless-tools packages:
aptitude update aptitude install b43-fwcutter wireless-tools
If you have an Internet connection available, allow the b43-fwcutter package to fetch and extract firmware.
3. Load the b43legacy module:
modprobe b43legacy
4. Verify your device now has an available interface:
iwconfig
5. Raise the interface to activate the radio, for example:
ifconfig wlan0 up
6. [:WiFi/HowToUse:Configure] your wireless interface as appropriate.
Troubleshooting
- Examine the kernel ring buffer (dmesg) to verify the required firmware files are being loaded by the driver. Lack of firmware is the usual reason for the "SIOCSIFFLAGS: No such file or directory" error message.
- Run "dpkg-reconfigure -plow b43-fwcutter" to fetch and extract firmware again. Firmware will only be fetched if not already present in the /lib/firmware/[b43|b43legacy] directories on your system.
If necessary, firmware can be manually acquired and extracted using the b43-fwcutter utility, see http://wireless.kernel.org/en/users/Drivers/b43#firmwareinstallation
?Anchor(ndiswrapper)
NDISwrapper
- This should only be used as a last resort, if the device is not supported by the native drivers (eg. Broadcom USB devices).
- Etch users: Before resorting to NDISwrapper, try using the b43 or b43legacy drivers via an etchnhalf kernel, as described in the [#bcm43xx_troubleshoot bcm43xx troubleshooting] section.
[:NdisWrapper:More information] on NDISwrapper is available on this wiki.
Blacklist native driver
If loaded, the native bcm43xx driver will conflict with NDISwrapper. To unload and disable:
modprobe -r bcm43xx echo blacklist bcm43xx >> /etc/modprobe.d/blacklist.local
Module installation (via module-assistant)
aptitude install module-assistant wireless-tools && m-a prepare && m-a a-i ndiswrapper modprobe ndiswrapper echo ndiswrapper >> /etc/modules
NDISwrapper is now installed on your system. Install the required [#ndisdriver NDIS driver] as necessary.
Module Installation (manual)
The following procedure is only necessary for Etch systems which require a version of NDISwrapper greater than 1.28.
Install necessary development packages, along with wireless-tools:
aptitude install build-essential linux-headers-$(uname -r) wireless-tools
Download and compile the NDISwrapper [http://sourceforge.net/project/showfiles.php?group_id=93482 source code]. For example, to acquire and build NDISwrapper version 1.53:
mkdir tmp && cd tmp wget http://superb-east.dl.sourceforge.net/sourceforge/ndiswrapper/ndiswrapper-1.53.tar.gz tar xvf ndiswrapper-1.53.tar.gz cd ndiswrapper-1.53 make su make install modprobe ndiswrapper echo ndiswrapper >> /etc/modules
NDISwrapper is now installed on your system. Install the required [#ndisdriver NDIS driver] as necessary.
?Anchor(ndisdriver)
Install NDIS driver
The following procedure is specific to the "Dell Wireless Card 1390" (man: 14e4, dev: 4311) device and is provided as an example only. Consult the [:NdisWrapper:NDISwrapper page] for links to further information on your specific device.
1. Acquire the NDIS driver from Dell's FTP site:
wget http://ftp.us.dell.com/network/R151517.EXE
2. Extract its contents:
unzip -a R151517.EXE
3. Install the driver:
ndiswrapper -i DRIVER/bcmwl5.inf
4. To verify NDIS driver installation, list the currently installed drivers:
