IWN(4) FreeBSD Kernel Interfaces Manual 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 pci
device wlan
device firmware
You also need to select a firmware for your device. Choose one from:
device iwn1000fw
device iwn100fw
device iwn105fw
device iwn135fw
device iwn2000fw
device iwn2030fw
device iwn4965fw
device iwn5000fw
device iwn5150fw
device iwn6000fw
device iwn6000g2afw
device iwn6000g2bfw
device iwn6050fw
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 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.
