NAME

     iwn -- Intel Wireless WiFi Link 4965/1000/5000/5150/5300/6000/6050 IEEE
     802.11n 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 iwn4965fw
           device iwn1000fw
           device iwn5000fw
           device iwn5150fw
           device iwn6000fw
           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"
           iwn4965fw_load="YES"
           iwn1000fw_load="YES"
           iwn5000fw_load="YES"
           iwn5150fw_load="YES"
           iwn6000fw_load="YES"
           iwn6050fw_load="YES"

DESCRIPTION

     The iwn driver provides support for Intel Wireless WiFi Link 4965, 1000,
     5000 and 6000 series of PCI-Express network adapters.  iwn supports
     station, adhoc, 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.
