Looking for drivers for this Broadcom bluetooth device for win 10 64-bit. We are in the process of upgrading to Win 10 enterprise wide. Elitebook 8570p is the computer. Update Your Chipset Drivers. Chipset drivers are responsible for controlling communication between various components in your system: the processor, the video card, the hard drives, PCI devices and system memory. Keeping these drivers up to date is important - especially if you are experiencing generally sluggish system performance.
b43 and b43legacy are drivers for the 802.11b/g/n family of wireless chips that Broadcom produces.
- The b43, b43legacy, brcmsmac and wl drivers do not support any USB devices. Using Windows' binary drivers: NDISwrapper plus the relevant Windows NDIS driver. This is a workaround for devices not supported by the Linux kernel, such as USB devices based on Broadcom wireless chips (other than the BCM4320). B43 and b43legacy.
- Speeding endangers cyclists, pedestrians, and drivers. Even small increases in speed increase the lethality of a crash with a vulnerable user, and speed affects everything from how fast a car can stop to how quickly a moment of distraction becomes a disaster.

- The BCM communicates with other on-board computers via the car's vehicle bus, and its main application is controlling load drivers – actuating relays that in turn perform actions in the vehicle such as locking the doors or dimming the interior lighting.
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).
Please read this whole document and the FAQ before asking questions to the developers.

- 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:
Driver Bcm43142a0 Download
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.

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
Driver Bcm2045a0 Windows 10
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:
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.
Basic info | b43 | STA (wl) | brcmsmac |
Open source | yes | no | yes |
In kernel | yes | no | yes |
Supported buses | b43 | wl | brcmsmac |
ssb | yes | yes | no |
bcma | yes | yes | yes |
usb | no | no | no |
Supported PHYs | b43 | wl | brcmsmac |
G | yes | yes | no |
N | yes | yes | yes |
LP | yes | yes | no |
HT | yes | no | no |
LCN | no | yes | yes |
Supported modes | b43 | wl | brcmsmac |
Managed | yes | yes | yes |
Ad-Hoc | yes | yes | unknown |
Monitor | yes | yes | no |
AP | yes | no | no |
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.
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.
