iwm — Intel IEEE 802.11ac wireless network driver
Contents
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.
Diagnostics
iwm%d:devicetimeout The driver will reset the hardware. This should not happen.
iwm%d:firmwareerror The onboard microcontroller crashed for some reason. The driver will reset the
hardware. This should not happen.
iwm%d:timeoutwaitingforfirmwareinitializationtocomplete The onboard microcontroller failed to
initialize in time. This should not happen.
iwm%d:couldnotloadfirmwareimage'%s' The driver failed to load the firmware image using the
firmware(9) subsystem. Verify the iwmfw(4) firmware module is present.
iwm%d:couldnotloadbootfirmware An attempt to upload the boot firmware image to the onboard
microcontroller failed. This should not happen.
iwm%d:couldnotloadmicrocode An attempt to upload the microcode image to the onboard microcontroller
failed. This should not happen.
iwm%d:couldnotloadmainfirmware An attempt to upload the main firmware image to the onboard
microcontroller failed. This should not happen.
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”:
ifconfigwlancreatewlandeviwm0ssidmy_netup
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

Synopsis
To compile this driver into the kernel, include the following lines in your kernel configuration file:
deviceiwmdevicepcidevicewlandevicefirmware
You also need to select a firmware for your device. Choose one from:
deviceiwm3160fwdeviceiwm3168fwdeviceiwm7260fwdeviceiwm7265fwdeviceiwm8000Cfwdeviceiwm8265fwdeviceiwm9000fwdeviceiwm9260fw
Or you can use
deviceiwmfw
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"
