| 7 | b43 is a driver for the Broadcom 43xx series wireless devices. |
| 8 | |
| 9 | Check "lspci" for something like |
| 10 | "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller" |
| 11 | to determine whether you own such a device. |
| 12 | |
| 13 | This driver supports the new BCM43xx IEEE 802.11G devices, but not |
| 14 | the old IEEE 802.11B devices. Old devices are supported by |
| 15 | the b43legacy driver. |
| 16 | Note that this has nothing to do with the standard that your AccessPoint |
| 17 | supports (A, B, G or a combination). |
| 18 | IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints. |
| 19 | |
| 20 | It is safe to include both b43 and b43legacy as the underlying glue |
| 21 | layer will automatically load the correct version for your device. |
| 22 | |
| 23 | This driver uses V4 firmware, which must be installed separately using |
| 24 | b43-fwcutter. |
| 25 | |
| 26 | This driver can be built as a module (recommended) that will be called "b43". |
| 27 | If unsure, say M. |
