IWM(4)                DragonFly 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 You also need to select a firmware for your device. 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"

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 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.

LOADER TUNABLES

hw.iwm.msi.enable By default, the driver will use MSI if it is supported. This behavior can be turned off by setting this tunable to 0. hw.iwm.power_scheme Power management scheme: 1 = active, 2 = balanced (default), 3 = low power hw.iwm.lar.disable Allows disabling LAR (Location Aware Regulatory) feature: 0 = LAR enabled if available (default), 1 = LAR disabled

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: fw chunk addr 0x%x len %d failed to load Timed out waiting for a segment of the firmware to load. This should not happen. iwm%d: could not read firmware %s (error %d) The driver failed to load the firmware image using the firmware(9) subsystem. Verify the iwmfw(4) firmware module is present. iwm%d: Failed to start INIT ucode: %d An attempt to upload the INIT firmware image to the onboard microcontroller failed. This should not happen. iwm%d: could not load firmware An attempt to upload the REGULAR firmware image to the onboard microcontroller failed. This should not happen.
