| b43 is a driver for the Broadcom 43xx series wireless devices. |
| |
| Check "lspci" for something like |
| "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller" |
| to determine whether you own such a device. |
| |
| This driver supports the new BCM43xx IEEE 802.11G devices, but not |
| the old IEEE 802.11B devices. Old devices are supported by |
| the b43legacy driver. |
| Note that this has nothing to do with the standard that your AccessPoint |
| supports (A, B, G or a combination). |
| IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints. |
| |
| It is safe to include both b43 and b43legacy as the underlying glue |
| layer will automatically load the correct version for your device. |
| |
| This driver uses V4 firmware, which must be installed separately using |
| b43-fwcutter. |
| |
| This driver can be built as a module (recommended) that will be called "b43". |
| If unsure, say M. |
