IWN(4) 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. HARDWARE The iwn driver provides support for: • Intel Centrino Advanced-N 6200 • Intel Centrino Advanced-N 6205 • Intel Centrino Advanced-N 6230 • Intel Centrino Advanced-N 6235 • Intel Centrino Advanced-N + WiMAX 6250 • Intel Centrino Ultimate-N 6300 • Intel Centrino Wireless-N 100 • Intel Centrino Wireless-N 105 • Intel Centrino Wireless-N 130 • Intel Centrino Wireless-N 135 • Intel Centrino Wireless-N 1000 • Intel Centrino Wireless-N 1030 • Intel Centrino Wireless-N 2200 • Intel Centrino Wireless-N 2230 • Intel Centrino Wireless-N 4965 • Intel Centrino Wireless-N 5100 • Intel Centrino Wireless-N 6150 • Intel Centrino Wireless-N 6200 • Intel Centrino Wireless-N 6250 • Intel Centrino Wireless-N + WiMAX 6150 • Intel Ultimate N WiFi Link 5300 • Intel Wireless WiFi Link 4965 • Intel WiFi Link 5100 • Intel WiMAX/WiFi Link 5150 • Intel WiMAX/WiFi Link 5350 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 on- board 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 im- age 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.
