NAME

       bwi — Broadcom BCM43xx IEEE 802.11b/g wireless network driver

SYNOPSIS

       To compile this driver into the kernel, place the following lines in your kernel configuration file:

             device bwi
             device wlan
             device wlan_amrr
             device firmware

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             if_bwi_load="YES"

DESCRIPTION

       The bwi driver provides support for Broadcom BCM43xx based PCI/CardBus network adapters.

       It  supports  station  and  monitor  mode operation.  Only one virtual interface may be configured at any
       time.  For more information on configuring this device, see ifconfig(8).

       This driver requires firmware to be loaded before it will  work.   The  ports/net/bwi-firmware-kmod  port
       needs to be installed before ifconfig(8) will work.

HARDWARE

       The bwi driver supports Broadcom BCM43xx based wireless devices, including:

       The  bwi driver uses the older v3 version of Broadcom's firmware.  While this older firmware does support
       most BCM43xx parts, the bwn(4) driver works better for the newer chips it supports.  You must use the bwi
       driver if you are using older Broadcom chipsets (BCM4301, BCM4303 and BCM4306 rev 2).  The v4 version  of
       the firmware that bwn(4) uses does not support these chips.

EXAMPLES

       Join an existing BSS network (i.e., connect to an access point):

             ifconfig wlan create wlandev bwi0 inet 192.168.0.20 \
                 netmask 0xffffff00

       Join a specific BSS network with network name “my_net”:

             ifconfig wlan create wlandev bwi0 ssid my_net up

       Join a specific BSS network with 64-bit WEP encryption:

             ifconfig wlan create wlandev bwi0 ssid my_net \
                     wepmode on wepkey 0x1234567890 weptxkey 1 up

HISTORY

       The bwi driver first appeared in FreeBSD 8.0.

AUTHORS

       The bwi driver was written for DragonFly BSD by Sepherosa Ziehau and subsequently ported to FreeBSD.

BUGS

       Some card based on the BCM4306 and BCM4309 chips do not work properly on channel 1, 2 and 3.
