Click Sites and then add these website addresses one at a time to the list: You can only add one address at a time and you must click Add after each one. Note: Broadcom USB devices are handled by the brcmfmac driver. B43legacy: supports BCM4306 Rev 2 and cards that have only 802.11b capability. B43: supports all other models. Kernel automatically loads correct driver for the present hardware (it checks for revision of the 802.11 core). The Broadcom Windows driver will upload firmware into the Broadcom Bluetooth device on every startup, however for macOS this functionality is not supported out of the box. BrcmPatchRAM kext is a macOS driver which applies PatchRAM updates for Broadcom RAMUSB based devices. Hi, I bought a notebook Pavilion Dv6 with windows 7 but I had upgraded to windows 10 64bit last version. But my wi fi lost connection in time to time and the lost the deafult gateway.

1. Features
2. Device firmware installation

• The b43/b43legacy drivers require proprietary firmware to be loaded onto the wireless chip before it can operate, see below.

• If you have a Broadcom USB device, it's most likely a FullMAC device. See rndis_wlan for 14e4:4320 and brcmfmac for others. The b43/b43legacy driver is not meant to support such a device.

• It is possible to use only one driver at a moment, they are conflicting each other. See Switching between drivers for howto on choosing driver.

• LP-PHY devices: DMA errors on some machines with kernel 2.6. Problem was fixed in 3.0. Using PIO (module param) can be used as workaround for 2.6.

• BCM4318 chipset: AP mode does not work because of packet loss in high transmission rates. Hard to debug & fix.

• BCM4321: some cards do not work in DMA mode with kernel 3.1 and older. Problem was fixed in 3.2. A workaround for older kernel is to use PIO mode (b43.pio=1 module param).

• G-PHY devices: not working with kernels 3.15 and 3.16-rc1 (a regression). This was fixed in 3.15.5 (6f3f164) and 3.16-rc3 (2fc68eb).

To find out whether a PCI device is supported by the b43 or b43legacy drivers, issue this lspci command:

The command will output a string similar to this example:

Ignore everything, except the last part inside of the [ ]. Find that phrase in the below table to determine support.

Note that the PCI-ID is not in direct correlation with the Chip ID. Often the PCI-ID equals the Chip ID, but that is not always the case and it is a constant source of confusion.

For a list of available devices, please see the device list.

Please note that we do not support wl or brcm80211 drivers.

Working

• Station mode
• Mesh networking mode (b43 only)
• Access Point mode
• Ad-Hoc (IBSS) mode (b43 only)
• Monitor and Promisc mode.
• 'Monitor while operating' and multiple monitor interfaces.
• In-Hardware traffic de/encryption (relieves your CPU).
• LEDs to signal card state and traffic.
• In-Hardware MAC address filter (b43 only; impossible on b43legacy hardware)
• Packet injection (with radiotap; no FCS injection currently though hardware supports it - a radiotap flag is being discussed for this)
• Bluetooth coexistence protection, if the bluetooth card is physically connected to the wireless chip. (Does not protect against external BT dongles)
• Probably something we forgot to add here.

Not working yet

• Interference mitigation.
• 802.11n: HT
• 802.11n: aggregation
• 802.11n: 40MHz channels
• 5 GHz band

The Broadcom wireless chip needs proprietary software (called 'firmware') that runs on the wireless chip itself to work properly. This firmware is copyrighted by Broadcom and must be extracted from Broadcom's proprietary drivers. To get such firmware on your system, you must download the driver from a legal distribution point, extract it, and install it. This is accomplished different ways by different Linux distributions, so please read the section for yours for the best results. You will need an alternate working internet connection (by Ethernet cable, for example) since the firmware cannot be included with the distro itself.

Post details for missing distributions at b43-dev@lists.infradead.org . Note: the firmware from the binary drivers is copyrighted by Broadcom Corporation and cannot be redistributed.

Fedora

With Fedora 10 and above, you should install wget and the b43-fwcutter tool (which will extract firmware from the Windows driver):

Next use the instructions here, skipping b43-fwcutter installation part.

openSUSE

openSUSE 11.3 and above includes a utility that will automatically download the firmware and install it into its proper location. With working Internet access, run the following commands:

Ubuntu/Debian

In recent versions of Ubuntu and Debian, installing the firmware-b43-installer package will handle everything for you:

You will be asked to automatically fetch and install the firmware into the right location. Again, you will need an internet connection.

Ubuntu Community Documentation

Ubuntu also has a page detailing the process of installing Broadcom wireless drivers on their community documentation. If you have internet access on the device that you want to install the b43 driver onto, follow this link: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43%20-%20Internet%20access . If you do not have internet access on the device that has a b43 supported broadcom wireless chipset and would like to use b43, follow this link instead: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43%20-%20No%20Internet%20access.

Note that you can only follow one of the two guides, not both.

Gentoo

Gentoo systems supply a pre-compiled binary for b43-fwcutter. You need to:

and then follow the instructions below to download the Broadcom driver. The line that invokes b43-fwcutter will need to be changed to execute the program emerged above.

Mandriva

See the instructions at http://wiki.mandriva.com/en/Installing_wireless_network_cards_using_the_b43_driver

Other distributions not mentioned above

Note: You need to have a compiler and headers for libc installed, since you will have to build fwcutter from source

Install b43-fwcutter

Use version 018 of b43-fwcutter.
Download, extract the b43-fwcutter tarball and build it:

If verification of the GPG signature fails due to an unknown key, you need to import the following key:

If you are using the b43 driver from 3.2 kernel or newer:

After installing b43-fwcutter, download version 5.100.138 of Broadcom's proprietary driver and extract the firmware from it:

If you are using the b43 driver from older kernel:

After installing b43-fwcutter, download version 5.10.56.27.3 of Broadcom's proprietary driver and extract the firmware from it:

Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.

If you are using the b43legacy driver:

After installing b43-fwcutter, download version 3.130.20.0 of Broadcom's proprietary driver and extract the firmware from it:

Broadcom 4313 Driver Windows 7 Installer

Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.

Many different drivers are or have been in use to support Broadcom chipsets, so the terminology is very confusing. The sections below aim to help you understand what is what.

There is also b43legacy driver for some old cards: B-PHY and early G-PHY ones. These cards can't run new firmware, so hardware encryption is unsupported on them.

Please note b43 developers don't offer support for the STA (wl) driver due to the fact that it's mainly proprietary. Contact Broadcom's support.

If you have few drivers installed, system may auto-load different driver than the one you wanted to use. Manual (un)loading drivers can be done with modprobe tool.

Broadcom 4313 Driver Windows 7 Download

To unload all known drivers (you can pick only one command, if you know which driver is in use) perform:

To load specific driver use one of the following commands:

It is possible to prevent system from auto-loading some drivers by blacklisting them. This can be done with the following command:

If you plan to use wl, you should blacklist b43 and brcmsmac as well as bcma. Unfortunately wl does not use bcma bus driver, so this additional step is required.

If you encounter a bug, you should send a message to the b43/b43legacy mailing list at b43-dev@lists.infradead.org containing ALL of the following:

• A description of the problem at hand
• When it happens
• How to reproduce
• wlan configuration and authentication/encryption type
• The output of the following commands:

In addition the following may be of interest to developers:

• If you have built the kernel from git, tell which tree, the output of 'git describe'
• If the driver worked with earlier kernels, but has since stopped working, a bisection is of great value.

See developers page for some advanced info, tools.

Many people have donated money, hardware or other services to make this driver possible. Thanks! Please see the donations page for details.
