NAME
       iwi -- Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 driver

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

	     device iwi
	     device iwifw
	     device pci
	     device wlan
	     device firmware

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

	     if_iwi_load="YES"

       In  both	 cases,	place the following line in loader.conf(5) to acknowl-
       edge the	firmware license (see below):

	     legal.intel_iwi.license_ack=1

DESCRIPTION
       The iwi driver provides support for Intel  PRO/Wireless	2200BG/2915ABG
       MiniPCI	and 2225BG PCI network adapters.  iwi supports station,	adhoc,
       and monitor mode	operation.  Only one virtual interface may be  config-
       ured at any time.  For more information on configuring this device, see
       ifconfig(8).

       This  driver requires the firmware built	with the iwifw module to work.
       For  the	 loaded	 firmware  to  be  enabled  for	 use  the  license  at
       /usr/share/doc/legal/intel_iwi.LICENSE  must  be	 agreed	 by adding the
       following line to loader.conf(5):

	     legal.intel_iwi.license_ack=1

FILES
       /usr/share/doc/legal/intel_iwi.LICENSE  iwi firmware license

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

	     ifconfig wlan create wlandev iwi0 inet 192.168.0.20 \
		 netmask 0xffffff00

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

	     ifconfig wlan create wlandev iwi0 ssid my_net up

       Join a specific BSS network with	64-bit WEP encryption:

	     ifconfig wlan create wlandev iwi0 ssid my_net \
		     wepmode on	wepkey 0x1234567890 weptxkey 1 up

       Join a specific BSS network with	128-bit	WEP encryption:

	     ifconfig wlan create wlandev iwi0 wlanmode	adhoc ssid my_net \
		 wepmode on wepkey 0x01020304050607080910111213	weptxkey 1

DIAGNOSTICS
       iwi%d: device timeout  The driver will reset the	hardware.  This	should
       not happen.

       iwi%d: firmware error  The onboard  microcontroller  crashed  for  some
       reason.	The driver will	reset the hardware.  This should not happen.

       iwi%d: timeout waiting for firmware initialization to complete  The on-
       board  microcontroller  failed  to initialize in	time.  This should not
       happen.

       iwi%d: could not	load firmware image '%s'  The driver  failed  to  load
       the  firmware  image  using  the	 firmware(9)  subsystem.   Verify  the
       iwifw(4)	 firmware  module  is  installed  and  the  license  agreement
       loader(8) tunable has been set.

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

       iwi%d: could not	load microcode	An attempt to upload the microcode im-
       age to the onboard microcontroller failed.  This	should not happen.

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