NAME
     iwn -- Intel IEEE 802.11n wireless network 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 iwn1000fw
	   device iwn100fw
	   device iwn105fw
	   device iwn135fw
	   device iwn2000fw
	   device iwn2030fw
	   device iwn4965fw
	   device iwn5000fw
	   device iwn5150fw
	   device iwn6000fw
	   device iwn6000g2afw
	   device iwn6000g2bfw
	   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"
	   iwn1000fw_load="YES"
	   iwn100fw_load="YES"
	   iwn105fw_load="YES"
	   iwn135fw_load="YES"
	   iwn2000fw_load="YES"
	   iwn2030fw_load="YES"
	   iwn4965fw_load="YES"
	   iwn5000fw_load="YES"
	   iwn5150fw_load="YES"
	   iwn6000fw_load="YES"
	   iwn6000g2afw_load="YES"
	   iwn6000g2bfw_load="YES"
	   iwn6050fw_load="YES"

     iwn  supports  station and monitor mode operation.  Only one virtual inter-
     face 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 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.
