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 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 de- vice, 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 on- board 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 im- age 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.
