IWN(4)							   BSD Kernel Interfaces Manual 						    IWN(4)

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. SEE ALSO
