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

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

	   device iwi
	   device pci
	   device wlan
	   device firmware

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

	   if_iwi_load="YES"
	   wlan_load="YES"
	   firmware_load="YES"

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

	   iwi_bss_load="YES"
	   iwi_ibss_load="YES"
	   iwi_monitor_load="YES"

DESCRIPTION
     The iwi driver provides support for Intel PRO/Wireless 2200BG/2915ABG
     MiniPCI and 2225BG	PCI network adapters.

     By	default, the iwi 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_iwi/LICENSE must be agreed to and the follow-
     ing line be added 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 iwi0 inet 192.168.0.20 netmask 0xffffff00

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

	   ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

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

	   ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x1234567890 weptxkey 1

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

	   ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 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	crashes	for some rea-
     son.  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 hap-
     pen.

     iwi%d: could not load firmware image '%s'	The driver failed to load the
     firmware image using the firmware(9) subsystem.  Verify that the neces-
     sary firmware modules are loaded and the license agreement	loader(8) tun-
     able 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 image
     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.
