10 | b43 is a driver for the Broadcom 43xx series wireless devices. | |
11 | ||
12 | Check "lspci" for something like | |
13 | "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller" | |
14 | to determine whether you own such a device. | |
15 | ||
16 | This driver supports the new BCM43xx IEEE 802.11G devices, but not | |
17 | the old IEEE 802.11B devices. Old devices are supported by | |
18 | the b43legacy driver. | |
19 | Note that this has nothing to do with the standard that your AccessPoint | |
20 | supports (A, B, G or a combination). | |
21 | IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints. | |
22 | ||
23 | It is safe to include both b43 and b43legacy as the underlying glue | |
24 | layer will automatically load the correct version for your device. | |
25 | ||
26 | This driver uses V4 firmware, which must be installed separately using | |
27 | b43-fwcutter. | |
28 | ||
29 | This driver can be built as a module (recommended) that will be called "b43". | |
30 | If unsure, say M. | |
