BWI(4)							   BSD 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 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/bwi-firmware-kmod port needs to be installed before
     ifconfig(8) will work.

HARDWARE

     The bwi driver supports Broadcom BCM43xx based wireless devices, including:

	   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 1470	    BCM4318    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

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

SEE ALSO

     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 subsequently ported to FreeBSD.

BUGS

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