IWI(4)

NAME
iwi - Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 network driver

SYNOPSIS
To compile this driver into the kernel, include the following lines in your kernel configuration file:

device iwi
device iwifw
device pci
device wlan
device firmware

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

    if_iwi_load="YES"

In both cases, place the following line in loader.conf(5) to acknowledge the firmware license (see below):

    legal.intel_iwi.license_ack=1

DESCRIPTION
The iwi driver provides support for Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11a/b/g wireless network devices in station, adhoc, and monitor mode operation. Only one virtual interface may be configured at any time.

This driver requires the firmware built with the iwifw module to work. For the loaded firmware to be enabled for use the license at /usr/share/doc/legal/intel_iwi.LICENSE must be agreed by adding the following line to loader.conf(5):

    legal.intel_iwi.license_ack=1

For more information on configuring this device, see ifconfig(8).

HARDWARE
The iwi driver supports the following wireless network devices:

•   Intel PRO/Wireless 2200BG MiniPCI Network Connection
•   Intel PRO/Wireless 2225BG PCI Network Connection
•   Intel PRO/Wireless 2915ABG MiniPCI Network Connection

FILES
/usr/share/doc/legal/intel_iwi.LICENSE
    iwi firmware license

EXAMPLES
Join an existing BSS network (i.e., connect to an access point):

    ifconfig wlan create wlandev iwi0 inet 192.0.2.20/24

Join a specific BSS network with network name my_net:

    ifconfig wlan create wlandev iwi0 ssid my_net up

Join a specific BSS network with 64-bit WEP encryption:

    ifconfig wlan create wlandev iwi0 ssid my_net \
        wepmode on wepkey 0x1234567890 weptxkey 1 up

Join a specific BSS network with 128-bit WEP encryption:

    ifconfig wlan create wlandev iwi0 wlanmode adhoc ssid my_net \
        wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS

iwi%d: device timeout The driver will reset the hardware. This should not happen.

iwi%d: firmware error The onboard microcontroller crashed for some reason. The driver will reset the hardware. This should not happen.

iwi%d: timeout waiting for firmware initialization to complete The onboard microcontroller failed to initialize in time. This should not happen.

iwi%d: could not load firmware image '%s' The driver failed to load the firmware image using the firmware(9) subsystem. Verify the iwifw(4) firmware module is installed and the license agreement loader(8) tunable has been set.

iwi%d: could not load boot firmware An attempt to upload the boot firmware image to the onboard microcontroller failed. This should not happen.

iwi%d: could not load microcode An attempt to upload the microcode image to the onboard microcontroller failed. This should not happen.

iwi%d: could not load main firmware An attempt to upload the main firmware image to the onboard microcontroller failed. This should not happen.
