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 following
     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	uploaded
     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.
