|  | 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. |
