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 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 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 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. BSD May 16, 2009 BSD
