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 de-
     vices in station mode operation.  Only one virtual interface may be config-
     ured 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 onboard
     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 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.

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.
