IWM(4)		       FreeBSD Kernel Interfaces Manual			IWM(4)

NAME
     iwm -- Intel IEEE 802.11ac	wireless network driver

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

	   device iwm
	   device pci
	   device wlan
	   device firmware

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

	   device iwm3160fw
	   device iwm3168fw
	   device iwm7260fw
	   device iwm7265fw
	   device iwm8000Cfw
	   device iwm8265fw
	   device iwm9000fw
	   device iwm9260fw

     Or	you can	use

	   device iwmfw

     to	include	them all.

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

	   if_iwm_load="YES"
	   iwm3160fw_load="YES"
	   iwm3168fw_load="YES"
	   iwm7260fw_load="YES"
	   iwm7265fw_load="YES"
	   iwm8000Cfw_load="YES"
	   iwm8265fw_load="YES"
	   iwm9000fw_load="YES"
	   iwm9260fw_load="YES"

DESCRIPTION
     The iwm driver provides support for:

	   Intel Dual Band Wireless AC 3160
	   Intel Dual Band Wireless AC 3165
	   Intel Dual Band Wireless AC 3168
	   Intel Dual Band Wireless AC 7260
	   Intel Dual Band Wireless AC 7265
	   Intel Dual Band Wireless AC 8260
	   Intel Dual Band Wireless AC 8265
	   Intel Dual Band Wireless AC 9260
	   Intel Dual Band Wireless AC 9270
	   Intel Dual Band Wireless AC 946X
	   Intel Dual Band Wireless AC 9560

     iwm supports station 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 iwmfw module to work.

     Currently,	iwm only supports 802.11b and 802.11g modes.  It will not as-
     sociate to	access points that are configured to operate only in 802.11n
     or	802.11ac modes.

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

	   ifconfig wlan create	wlandev	iwm0 inet 192.168.0.20 \
	       netmask 0xffffff00

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

	   ifconfig wlan create	wlandev	iwm0 ssid my_net up

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

	   ifconfig wlan create	wlandev	iwm0 ssid my_net \
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

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

	   ifconfig wlan create	wlandev	iwm0 wlanmode adhoc ssid my_net	\
	       wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

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

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

     iwm%d: timeout waiting for	firmware initialization	to complete  The on-
     board microcontroller failed to initialize	in time.  This should not hap-
     pen.

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

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

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

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