SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:


.Cd device siba_bwn
.Cd device bwn
.Cd device wlan
.Cd device wlan_amrr
.Cd 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 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.

HARDWARE

The bwn driver supports Broadcom BCM43xx based wireless devices, including:
Card      Chip      Bus      Standard
Apple Airport Extreme BCM4318 PCI     b/g
ASUS WL-138g  BCM4318 PCI     b/g
Buffalo WLI-CB-G54S   BCM4318 CardBus b/g
Dell Wireless 1390    BCM4311 Mini PCI        b/g
Dell Wireless 1470    BCM4318 Mini PCI        b/g
Dell Truemobile 1400  BCM4309 Mini PCI        b/g
HP Compaq 6715b       BCM4312 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
US Robotics 5411      BCM4318 CardBus b/g
 

Users of older Broadcom chipsets (BCM4301, BCM4303 and BCM4306 rev 2) must use bwi(4) because the v4 version of the firmware does not support these chips. The newer firmware is too big to fit into these old chips.

EXAMPLES

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

LOADER TUNABLES

Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.bwn.msi_disable
  This tunable disables MSI support on the hardware. The default value is 0.
hw.bwn.usedma
  This tunable enables DMA operations on the hardware. If the value is 0, PIO mode would be used. The default value is 1.

SEE ALSO

HISTORY

The bwn driver first appeared in
.Fx 8.1 .

CAVEATS

Some LP PHY devices have DMA operation problems that in that case try to use PIO mode.
