**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]]
  * HT-PHY: no support for 5 GHz
  * No support for 802.11n features (HT, aggregation, 40 MHz width)

===== 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.
