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.
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
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.
The bwn driver first appeared in
.Fx 8.1 .
.An -nosplit The bwn driver was written by
.An Weongyo Jeong <weongyo@FreeBSD.org>.
Some LP PHY devices have DMA operation problems that in that case try to use PIO mode.
