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"
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. You need
to install the ports/net/iwi-firmware-kmod port before ifconfig(8) will
work.
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
ports/net/iwi-firmware-kmod port is installed correctly.
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.
