BWN(4) BSD Kernel Interfaces Manual BWN(4)
NAME
bwn -- 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 siba_bwn
device bwn
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_bwn_load="YES"
DESCRIPTION
The bwn 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/bwn-firmware-kmod port needs to be installed before
ifconfig(8) will work. Most cases you need to use bwn_v4_ucode module but if you are a LP (low power) PHY user please uses bwn_v4_lp_ucode
module.

Join an existing BSS network (i.e., connect to an access point):
ifconfig wlan create wlandev bwn0 inet 192.168.0.20
netmask 0xffffff00
Join a specific BSS network with network name ``my_net'':
ifconfig wlan create wlandev bwn0 ssid my_net up
Join a specific BSS network with 64-bit WEP encryption:
ifconfig wlan create wlandev bwn0 ssid my_net
wepmode on wepkey 0x1234567890 weptxkey 1 up
