NAME
     iwn  --  Intel  Wireless  WiFi Link 4965/1000/5000/5150/5300/6000/6050 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 iwn1000fw
	   device iwn5000fw
	   device iwn5150fw
	   device iwn6000fw
	   device iwn6050fw

     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"
	   iwn1000fw_load="YES"
	   iwn5000fw_load="YES"
	   iwn5150fw_load="YES"
	   iwn6000fw_load="YES"
	   iwn6050fw_load="YES"

DESCRIPTION
     The iwn driver provides support for Intel Wireless WiFi  Link  4965,  1000,
     5000  and	6000  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  de-
     vice, 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 reason.
     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.
