.Dt WPI 4
.Sh NAME
.Nm wpi
.Nd "Intel 3945ABG Wireless LAN IEEE 802.11 driver"
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device wpi"
.Cd "device pci"
.Cd "device wlan"
.Cd "device wlan_amrr"
.Cd "device firmware"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following lines in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_wpi_load="YES"
wlan_load="YES"
wlan_amrr_load="YES"
firmware_load="YES"
.Ed
.Pp
In both cases, place the following line in
.Xr loader.conf 5
to load the firmware modules:
.Bd -literal -offset indent
wpifw_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver is an experimental driver providing support for the
.Tn Intel
3945ABG Wireless network adapter
.Pp
By default, the
.Nm
driver configures the adapter for BSS operation (aka infrastructure mode).
This mode requires the use of an access point.
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
.Pp
This driver requires firmware to be loaded before it will work.
For the loaded firmware to work the license at
.Pa /usr/share/doc/legal/intel_wpi/LICENSE
must be agreed to and the following line be added to
.Xr loader.conf 5 :
.Pp
.Dl "legal.intel_wpi.license_ack=1"
.Sh FILES
.Bl -tag -width ".Pa /usr/share/doc/legal/intel_wpi/LICENSE" -compact
.It Pa /usr/share/doc/legal/intel_wpi/LICENSE
.Nm
firmware license
.El
.Sh EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
.Pp
.Dl "ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00"
.Pp
Join a specific BSS network with network name
.Dq Li my_net :
.Pp
.Dl "ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net"
.Pp
Join a specific BSS network with 40-bit WEP encryption:
.Bd -literal -offset indent
ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
wepmode on wepkey 0x1234567890 weptxkey 1
.Ed
.Pp
Join a specific BSS network with 104-bit WEP encryption:
.Bd -literal -offset indent
ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
.Ed
.Sh DIAGNOSTICS
.Bl -diag
.Xr firmware 9
subsystem.
Verify that the necessary firmware modules are loaded and the
license agreement
.Xr loader 8
tunable has been set.
.It "wpi%d: could not load firmware"
An attempt to upload the firmware image to the onboard microcontroller failed.
This should not happen.
.It "wpi%d: fatal firmware error"
An unknown error has occurred in the uploaded firmware, you may have to
unload/reload the driver to continue.
.It "wpi%d: Radio transmitter is switched off"
The hardware switch controlling the radio is currently turned off.
Data transmission is not possible in this state.
.Sh BUGS
Not all the error messages are documented here.
.Pp
Automatic recovery of firmware failures is not currently supported, nor is
detection of toggling the radio switch on.
.Pp
Background scanning is not currently supported.
