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:

You also need to select a firmware for your device. Choose one from:

Or you can use

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 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’:

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.
