NAME

iwn - Intel Wireless WiFi Link 4965AGN IEEE 802.11n 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 device firmware

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

 if_iwn_load="YES"
 

DESCRIPTION

The driver provides support for Intel Wireless WiFi Link 4965AGN PCI-Express network adapters. 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.

Le trou avait une porte tout à fait ronde
comme un hublot, peinte en vert, avec un bouton
de cuivre jaune bien brillant, exactement au centre.

Cette porte ouvrait sur un vestibule en forme de tube,
comme un tunnel: un tunnel très confortable,
sans fumée, aux murs lambrissés, au sol dallé
et garni de tapis; il était meublé de chaises cirées
et de quantité de patères pour les chapeaux
et les manteaux - le Hobbit aimait les visites.
