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 associate 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 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.
