BWN(4)							   BSD 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 configur-
     ing 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.

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
