BWI(4)		       FreeBSD Kernel Interfaces Manual			BWI(4)

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 inter-
     face 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, includ-
     ing:

	   Card			    Chip       Bus	   Standard
	   Apple Airport Extreme    BCM4306    PCI	   b/g
	   Apple Airport Extreme    BCM4318    PCI	   b/g
	   ASUS	WL-138g		    BCM4318    PCI	   b/g
	   Buffalo WLI-CB-G54S	    BCM4318    CardBus	   b/g
	   Buffalo WLI-PCI-G54S	    BCM4306    PCI	   b/g
	   Compaq R4035	onboard	    BCM4306    PCI	   b/g

	   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

     arp(4), cardbus(4), intro(4), pci(4), wlan(4), wlan_amrr(4), ifconfig(8),
     wpa_supplicant(8)

HISTORY
     The bwi driver first appeared in FreeBSD 8.0.

AUTHORS
     The bwi driver was	written	for DragonFly BSD by Sepherosa Ziehau and sub-
     sequently ported to FreeBSD.

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