WPI(4)			 BSD Kernel Interfaces Manual			WPI(4)

NAME
     wpi -- Intel 3945ABG Wireless LAN IEEE 802.11 driver

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device wpi
	   device pci
	   device wlan
	   device wlan_amrr
	   device firmware

     Alternatively, to load the	driver as a module at boot time, place the
     following lines in	loader.conf(5):

	   if_wpi_load="YES"
	   wlan_load="YES"
	   wlan_amrr_load="YES"
	   firmware_load="YES"

     In	both cases, place the following	line in	loader.conf(5) to load the
     firmware modules:

	   wpifw_load="YES"

DESCRIPTION
     The wpi driver is an experimental driver providing	support	for the	Intel
     3945ABG Wireless network adapter

     By	default, the wpi driver	configures the adapter for BSS operation (aka
     infrastructure mode).  This mode requires the use of an access point.

     For more information on configuring this device, see ifconfig(8).

     This driver requires firmware to be loaded	before it will work.  For the
     loaded firmware to	work the license at
     /usr/share/doc/legal/intel_wpi/LICENSE must be agreed to and the follow-
     ing line be added to loader.conf(5):

	   legal.intel_wpi.license_ack=1

FILES
     /usr/share/doc/legal/intel_wpi/LICENSE  wpi firmware license

EXAMPLES
     Join an existing BSS network (i.e., connect to an access point):

	   ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00

     Join a specific BSS network with network name "my_net":

	   ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

     Join a specific BSS network with 40-bit WEP encryption:

	   ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x1234567890 weptxkey 1

     Join a specific BSS network with 104-bit WEP encryption:

	   ifconfig wpi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS
     firmware(9) subsystem.  Verify that the necessary firmware	modules	are
     loaded and	the license agreement loader(8)	tunable	has been set.

     wpi%d: could not load firmware  An	attempt	to upload the firmware image
     to	the onboard microcontroller failed.  This should not happen.

     wpi%d: fatal firmware error  An unknown error has occurred	in the up-
     loaded firmware, you may have to unload/reload the	driver to continue.

     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.

BUGS
     Not all the error messages	are documented here.

     Automatic recovery	of firmware failures is	not currently supported, nor
     is	detection of toggling the radio	switch on.

     Background	scanning is not	currently supported.
