NAME

iwm – Intel IEEE 802.11ac wireless network driver

CONTENTS

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 iwm7260fw device iwm7265fw device iwm8000Cfw device iwm8265fw

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"
iwm7260fw_load="YES"
iwm7265fw_load="YES"
iwm8000Cfw_load="YES"
iwm8265fw_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 7260
Intel Dual Band Wireless AC 7265
Intel Dual Band Wireless AC 8260
 

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.

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.
