IWM(4)			 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 iwm7265Dfw
	 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"
	 iwm7265Dfw_load="YES"
	 iwm8000Cfw_load="YES"
	 iwm8265fw_load="YES"
	 iwm9000fw_load="YES"
	 iwm9260fw_load="YES"
DESCRIPTION
 The iwm	 driver	supports running most Intel Wireless AC	series network
 devices in station mode operation. Only	one virtual interface may be
 configured at any time. This driver requires the firmware built with
 the iwmfw(4) module to work.
 For more	information on configuring this	device,	see ifconfig(8).
HARDWARE
 The iwm driver supports the following PCIe Wi-Fi	devices:
  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
EXAMPLES
 Join an existing	BSS network (i.e., connect to an access	point):
	 ifconfig wlan create wlandev iwm0 inet 192.0.2.20/24
 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
 reason.	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
 happen.
 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 im-
 age 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.

BUGS
 Currently, iwm only supports 802.11a/b/g modes.	 It will not associate
 to access points	that are configured to	 operate only	in 802.11n/ac
 modes.
