NAMEbwi -- Broadcom BCM43xx IEEE 802.11b/g wireless network driver
SYNOPSISTo 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"
DESCRIPTIONThe 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 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.
HARDWAREThe 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
EXAMPLESJoin 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

HISTORYThe bwi driver first appeared in FreeBSD 8.0.
AUTHORSThe bwi driver was written for DragonFly BSD by Sepherosa Ziehau and subsequently ported to FreeBSD.
BUGSSome card based on the BCM4306 and BCM4309 chips do not work properly on channel 1, 2 and 3. BWI(4)
