IWI(4) MidnightBSD Kernel Interfaces Manual IWI(4)

NAME

iwi — Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 driver

SYNOPSIS

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

device iwi
device pci
device wlan
device firmware

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

if_iwi_load="YES"
wlan_load="YES"
firmware_load="YES"

In both cases, place the following lines in loader.conf(5) to load the firmware modules:

iwi_bss_load="YES"
iwi_ibss_load="YES"
iwi_monitor_load="YES"

DESCRIPTION

The iwi driver provides support for Intel PRO/Wireless 2200BG/2915ABG MiniPCI and 2225BG PCI network adapters.

By default, the iwi driver configures the adapter for BSS operation (aka infrastructure mode). This mode requires the use of an access point.

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

This driver requires firmware to be loaded before it will work. For the loaded firmware to work the license at /usr/share/doc/legal/intel_iwi/LICENSE must be agreed to and the following line be added to loader.conf(5):

legal.intel_iwi.license_ack=1

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 iwi0 inet 192.168.0.20 netmask 0xffffff00

Join a specific BSS network with network name ‘‘my_net’’:

ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

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

ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
wepmode on wepkey 0x1234567890 weptxkey 1

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

ifconfig iwi0 inet 192.168.0.20 netmask 0xffffff00 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 crashes 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 that the necessary firmware modules are loaded 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.
