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"

       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.
