BWN(4)                 FreeBSD Kernel Interfaces Manual                 BWN(4)

NAME
     bwn - 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 siba_bwn
           device bwn
           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_bwn_load="YES"

DESCRIPTION
     The bwn 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/bwn-firmware-kmod port needs to be installed before ifconfig(8)
     will work.  Most cases you need to use bwn_v4_ucode module but if you are
     a LP (low power) PHY user please uses bwn_v4_lp_ucode module.

HARDWARE
     The bwn driver supports Broadcom BCM43xx based wireless devices,
     including:

                           BCM4306 CardBus  b/g
     US Robotics 5411      BCM4318 CardBus  b/g

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

           ifconfig wlan create wlandev bwn0 inet 192.168.0.20 \
               netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

           ifconfig wlan create wlandev bwn0 ssid my_net up

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

           ifconfig wlan create wlandev bwn0 ssid my_net \
                   wepmode on wepkey 0x1234567890 weptxkey 1 up
