IWN(4)		       FreeBSD Kernel Interfaces Manual			IWN(4)

NAME
     iwn -- Intel Wireless WiFi	Link 4965/5000 IEEE 802.11n driver

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

	   device iwn
	   device pci
	   device wlan
	   device firmware

     You also need to select a firmware	for your device.  Choose one from:

	   device iwn4965fw
	   device iwn5000fw
	   device iwn5100fw

     Or	you can	use

	   device iwnfw

     to	include	them all.

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

	   if_iwn_load="YES"
	   iwn4965fw_load="YES"
	   iwn5000fw_load="YES"
	   iwn5100fw_load="YES"

DESCRIPTION
     The iwn driver provides support for Intel Wireless	WiFi Link 4965 and
     5000 series of PCI-Express	network	adapters.  iwn 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 iwnfw module to work.

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

	   ifconfig wlan create	wlandev	iwn0 inet 192.168.0.20 \
	       netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig wlan create	wlandev	iwn0 ssid my_net up

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

	   ifconfig wlan create	wlandev	iwn0 ssid my_net \
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

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

	   ifconfig wlan create	wlandev	iwn0 wlanmode adhoc ssid my_net	\
	       wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

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

     iwn%d: firmware error  The	onboard	microcontroller	crashed	for some rea-
     son.  The driver will reset the hardware.	This should not	happen.

     iwn%d: timeout waiting for	firmware initialization	to complete  The
     onboard microcontroller failed to initialize in time.  This should	not
     happen.

     iwn%d: could not load firmware image '%s'	The driver failed to load the
     firmware image using the firmware(9) subsystem.  Verify the iwnfw(4)
     firmware module is	present.

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

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

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