IPW(4) FreeBSD Kernel Interfaces Manual IPW(4)
NAME
ipw - Intel PRO/Wireless 2100 IEEE 802.11a/b driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
device ipw
device ipwfw
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_ipw_load="YES"
In both cases, place the following line in loader.conf(5) to acknowledge
the firmware license (see below):
legal.intel_ipw.license_ack=1
DESCRIPTION
The ipw driver provides support for Intel PRO/Wireless 2100 802.11a/b
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 ipwfw module to work.
For the loaded firmware to be enabled for use the license at
/usr/share/doc/legal/intel_ipw.LICENSE must be agreed by adding the
following line to loader.conf(5):
legal.intel_ipw.license_ack=1
For more information on configuring this device, see ifconfig(8).
HARDWARE
The ipw driver provides support for the Intel PRO/Wireless 2100a/b
MiniPCI network adapter.

EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
ifconfig wlan create wlandev ipw0 inet 192.0.2.20/24
Join a specific BSS network with network name my_net:
ifconfig wlan create wlandev ipw0 ssid my_net up
Join a specific BSS network with 64-bit WEP encryption:
ifconfig wlan create wlandev ipw0 ssid my_net \
wepmode on wepkey 0x1234567890 weptxkey 1 up
Join a specific BSS network with 128-bit WEP encryption:
ifconfig wlan create wlandev ipw0 wlanmode adhoc ssid my_net \
wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
DIAGNOSTICS
ipw%d: device timeout The driver will reset the hardware. This should
not happen.
ipw%d: firmware error The onboard microcontroller crashes for some
reason. The driver will reset the hardware. This should not happen.
ipw%d: timeout waiting for firmware initialization to complete The
onboard microcontroller failed to initialize in time. This should not
happen.
ipw%d: could not load firmware image '%s' The driver failed to load the
firmware image using the firmware(9) subsystem. Verify the ipwfw(4)
firmware module is installed and the license agreement loader(8) tunable
has been set.
ipw%d: could not load microcode An attempt to upload the microcode image
to the onboard microcontroller failed. This should not happen.
ipw%d: could not load firmware An attempt to upload the firmware image
to the onboard microcontroller failed. This should not happen.
