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  in-
       terface may be configured at any	time.  For more	information on config-
       uring 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, in-
       cluding:

	     HP	nx6125		      BCM4319	 PCI	     b/g
	     Linksys WPC54G Ver	3     BCM4318	 CardBus     b/g
	     Linksys WPC54GS Ver 2    BCM4318	 CardBus     b/g
	     TRENDnet TEW-401PCplus   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 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.
