     bwn — Broadcom BCM43xx IEEE 802.11b/g wireless network driver


     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



     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 configuring 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.


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

     Join an existing BSS network (i.e., connect to an access point):

           ifconfig wlan create wlandev bwn0 inet \
               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

     The bwn driver first appeared in FreeBSD 8.1.
