29.Os
30.Sh NAME
31.Nm bwi
32.Nd Broadcom BCM43xx IEEE 802.11b/g wireless network driver
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device bwi"
39.Cd "device wlan"
40.Cd "device wlan_amrr"
41.Cd "device firmware"
42.Ed
43.Pp
44Alternatively, to load the driver as a
45module at boot time, place the following line in
46.Xr loader.conf 5 :
47.Bd -literal -offset indent
48if_bwi_load="YES"
49.Ed
50.Sh DESCRIPTION
51The
52.Nm
53driver provides support for Broadcom BCM43xx based
54PCI/CardBus network adapters.
55.Pp
56It supports
57.Cm station
58and
59.Cm monitor
60mode operation.
61Only one virtual interface may be configured at any time.
62For more information on configuring this device, see
63.Xr ifconfig 8 .
64.Pp
65This driver requires firmware to be loaded before it will work.
66The
67.Pa ports/net/bwi-firmware-kmod
68port needs to be installed before
69.Xr ifconfig 8
70will work.
71.Sh HARDWARE
72The
73.Nm
74driver supports Broadcom BCM43xx based wireless devices, including:
75.Bl -column "Apple Airport Extreme" "BCM4306" "Mini PCI" "a/b/g" -offset 6n
76.It Em "Card" Ta Em "Chip" Ta Em "Bus" Ta Em "Standard"

92.It "US Robotics 5411	BCM4318	CardBus	b/g"
93.El
94.Pp
95The
96.Nm
97driver uses the older v3 version of Broadcom's firmware.
98While this older firmware does support most BCM43xx parts, the
99.Xr bwn 4
100driver works better for the newer chips it supports.
101You must use the
102.Nm
103driver if you are using older Broadcom chipsets (BCM4301, BCM4303 and
104BCM4306 rev 2).
105The v4 version of the firmware that
106.Xr bwn 4
107uses does not support these chips.
108.Sh EXAMPLES
109Join an existing BSS network (i.e., connect to an access point):
110.Bd -literal -offset indent
111ifconfig wlan create wlandev bwi0 inet 192.168.0.20 \e
112    netmask 0xffffff00
113.Ed
114.Pp
115Join a specific BSS network with network name
116.Dq Li my_net :
117.Pp
118.Dl "ifconfig wlan create wlandev bwi0 ssid my_net up"
119.Pp
120Join a specific BSS network with 64-bit WEP encryption:
121.Bd -literal -offset indent
122ifconfig wlan create wlandev bwi0 ssid my_net \e
123        wepmode on wepkey 0x1234567890 weptxkey 1 up

134.Sh HISTORY
135The
136.Nm
137driver first appeared in
138.Fx 8.0 .
139.Sh AUTHORS
140.An -nosplit
141The
142.Nm
143driver was written for DragonFly BSD by
144.An Sepherosa Ziehau
145and subsequently ported to
146.Fx .
147.Sh BUGS
148Some card based on the BCM4306 and BCM4309 chips do not work properly
149on channel 1, 2 and 3.
