32.Sh NAME
33.Nm wpi
34.Nd "Intel 3945ABG Wireless LAN IEEE 802.11 driver"
35.Sh SYNOPSIS
36To compile this driver into the kernel,
37place the following lines in your
38kernel configuration file:
39.Bd -ragged -offset indent
40.Cd "device wpi"
41.Cd "device wpifw"
42.Cd "device pci"
43.Cd "device wlan"
44.Cd "device wlan_amrr"
45.Cd "device firmware"
46.Ed
47.Pp
48Alternatively, to load the driver as a
49module at boot time, place the following line in
50.Xr loader.conf 5 :
51.Bd -literal -offset indent
52if_wpi_load="YES"
53.Ed
54.Sh DESCRIPTION
55The
56.Nm
57driver provides support for the
58.Tn Intel
593945ABG Wireless network adapter.
60.Nm
61supports
62.Cm station ,
63.Cm adhoc ,
64and
65.Cm monitor
66mode operation.
67Only one virtual interface may be configured at any time.
68For more information on configuring this device, see
69.Xr ifconfig 8 .
70.Pp
71This driver requires the firmware built with the
72.Nm wpifw
73module to work.

103.Sh DIAGNOSTICS
104.Bl -diag
105.It "wpi%d: could not load firmware image '%s'"
106The driver failed to load the firmware image using the
107.Xr firmware 9
108subsystem.
109Verify the
110.Xr wpifw
111firmware module is installed.
112.It "wpi%d: fatal firmware error"
113An unknown error has occurred in the uploaded firmware, you may have to
114unload/reload the driver to continue.
115.It "wpi%d: Radio transmitter is switched off"
116The hardware switch controlling the radio is currently turned off.
117Data transmission is not possible in this state.
