 +**b43** and **b43legacy** are wireless drivers for Broadcom [[en/​developers/​Documentation/​Glossary#​softmac|SoftMAC]] chipsets. Kernel will automatically pick a proper module for you:
 +  * **b43** for any new (supported) hardware
 +  * **b43legacy** for BCM4301 and early BCM4306 versions
 +
 +===== Summary =====
 +
 +  * You need to have firmware files (usually in ''/​lib/​firmware/''​) so **b43(legacy)** can upload them to the card and run properly.
 +  * For [[en/​developers/​Documentation/​Glossary#​fullmac|FullMAC]] devices support see [[en/​users/​Drivers/​brcm80211|brcmfmac]] and [[en/​users/​Drivers/​rndis_wlan|rndis_wlan]]
 +
 +===== Known problems & limitations =====
 +
 +  * Some stalls (on G-PHY only?) possibly related to CCK vs. OFDM, see [[https://​lists.openwrt.org/​pipermail/​openwrt-devel/​2012-August/​016432.html|WRT54g / b43 / mac802.11 BREAKTHROUGH]]
 +  * N-PHY: 5 GHz support requires kernel 3.17+
 +  * HT-PHY: no support for 5 GHz
 +  * No support for 802.11n features (HT, aggregation,​ 40 MHz width)
 +
 +===== Resolved problems =====
 +
 +  * G-PHY devices: not working with kernels 3.15 and 3.16-rc1 (a regression). This was fixed in 3.15.5 ([[https://​git.kernel.org/​cgit/​linux/​kernel/​git/​stable/​linux-stable.git/​commit/?​h=linux-3.15.y&​id=6f3f164bd0efe9a090cd74e08d6195c95024a1d1|6f3f164]]) and 3.16-rc3 ([[http://​git.kernel.org/​cgit/​linux/​kernel/​git/​torvalds/​linux.git/​commit/?​id=2fc68eb122c7ea6cd5be1fe7d6650c0beb2f4f40|2fc68eb]]).
 +  * Scanning/​connectivity problems: caused by **b43** bug exposed with kernel 3.8 (by [[http://​git.kernel.org/​cgit/​linux/​kernel/​git/​torvalds/​linux.git/​commit/?​id=0172bb75073e11a5aa9d8a953bdaefb8709f00c8|0172bb7]]). Fixed in kernel 3.14 (by [[http://​git.kernel.org/​cgit/​linux/​kernel/​git/​torvalds/​linux.git/​commit/?​id=64e5acb09ca6b50c97299cff9ef51299470b29f2|64e5acb]]) and backported to 3.13.2, 3.12.10, 3.10.29.

 +===== List of hardware =====
 +
 +To check for a present hardware model execute following command:
 +<​code>​lspci -nn -d 14e4:</​code>​
 +Please look carefully at device ID and chipset name.
