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

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

132.Sh HISTORY
133The
134.Nm
135driver first appeared in
136.Fx 8.0 .
137.Sh AUTHORS
138.An -nosplit
139The
140.Nm
141driver was written for
142.Dx
143by
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.
