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
	   Dell	Wireless 1390 BCM4311 Mini PCI b/g
	   Dell	Wireless 1470	    BCM4318    Mini PCI	   b/g
	   Dell	Truemobile 1300	r2  BCM4306    Mini PCI	   b/g
	   Dell	Truemobile 1400	    BCM4309    Mini 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

     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

     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.
