IWI(4)		       FreeBSD Kernel Interfaces Manual			IWI(4)

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 acknowledge
     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 configured
     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 fol-
     lowing 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 rea-
     son.  The driver will reset the hardware.	This should not	happen.

     iwi%d: timeout waiting for	firmware initialization	to complete  The
     onboard 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 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.
