IWN(4)

NAME
iwn - Intel IEEE 802.11n wireless network driver

SYNOPSIS
To compile this driver into the kernel, include the following lines in your kernel configuration file:

device iwn
device iwnfw
device pci
device wlan

Or you can use

device iwnfw

to include them all.

Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):

    if_iwn_load="YES"
    iwn1000fw_load="YES"
    iwn100fw_load="YES"
    iwn105fw_load="YES"
    iwn135fw_load="YES"
    iwn2000fw_load="YES"
    iwn2030fw_load="YES"
    iwn4965fw_load="YES"
    iwn5000fw_load="YES"
    iwn5150fw_load="YES"
    iwn6000fw_load="YES"
    iwn6000g2afw_load="YES"
    iwn6000g2bfw_load="YES"
    iwn6050fw_load="YES"

DESCRIPTION
The iwn driver provides support for:

Intel Centrino Advanced-N 6200
Intel Centrino Advanced-N 6205
Intel Centrino Advanced-N 6230
Intel Centrino Advanced-N 6235
Intel Centrino Advanced-N + WiMAX 6250
Intel Centrino Ultimate-N 6300
Intel Centrino Wireless-N 100
Intel Centrino Wireless-N 105
Intel Centrino Wireless-N 130
Intel Centrino Wireless-N 135
Intel Centrino Wireless-N 1000
Intel Centrino Wireless-N 1030
Intel Centrino Wireless-N 2200
Intel Centrino Wireless-N 2230
Intel Centrino Wireless-N 4965
Intel Centrino Wireless-N 5100
Intel Centrino Wireless-N 6150
Intel Centrino Wireless-N 6200
Intel Centrino Wireless-N 6250
Intel Centrino Wireless-N 6250
Intel Centrino Wireless-N + WiMAX 6150
Intel Ultimate N WiFi Link 5300
Intel Wireless WiFi Link 4965
Intel WiFi Link 5100
Intel WiMAX/WiFi Link 5150

iwn supports station and monitor 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 iwnfw module to work.

EXAMPLES
Join an existing BSS network (i.e., connect to an access point):

    ifconfig wlan create wlandev iwn0 inet 192.168.0.20 \
        netmask 0xffffff00

Join a specific BSS network with network name “my_net”:

    ifconfig wlan create wlandev iwn0 ssid my_net up

Join a specific BSS network with 64-bit WEP encryption:

    ifconfig wlan create wlandev iwn0 ssid my_net \
    	wepmode on wepkey 0x1234567890 weptxkey 1 up

Join a specific BSS network with 128-bit WEP encryption:

    ifconfig wlan create wlandev iwn0 wlanmode adhoc ssid my_net \
        wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS

iwn%d: device timeout The driver will reset the hardware. This should not happen.

iwn%d: firmware error The onboard microcontroller crashed for some reason. The driver will reset the hardware. This should not happen.

iwn%d: timeout waiting for firmware initialization to complete The onboard microcontroller failed to initialize in time. This should not happen.

iwn%d: could not load firmware image '%s' The driver failed to load the firmware image using the firmware(9) subsystem. Verify the iwnfw(4) firmware module is present.

iwn%d: could not load boot firmware An attempt to upload the boot firmware image to the onboard microcontroller failed. This should not happen.

iwn%d: could not load microcode An attempt to upload the microcode image to the onboard microcontroller failed. This should not happen.

iwn%d: could not load main firmware An attempt to upload the main firmware image to the onboard microcontroller failed. This should not happen.
