IPW(4) BSD Kernel Interfaces Manual IPW(4)

NAME

ipw — Intel PRO/Wireless 2100 IEEE 802.11 driver

SYNOPSIS

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

device ipw
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_ipw_load="YES"
wlan_load="YES"
firmware_load="YES"

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

ipw_bss_load="YES"
ipw_ibss_load="YES"
ipw_monitor_load="YES"

DESCRIPTION

The ipw driver provides support for the Intel PRO/Wireless 2100 MiniPCI network adapter.

By default, the ipw 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_ipw/LICENSE must be agreed to and the following line be added to loader.conf(5):

legal.intel_ipw.license_ack=1

FILES
/usr/share/doc/legal/intel_ipw/LICENSE

ipw firmware license

EXAMPLES

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

ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00

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

ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

Join a specific BSS network with 40-bit WEP encryption:

ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
wepmode on wepkey 0x1234567890 weptxkey 1

Join a specific BSS network with 104-bit WEP encryption:

ifconfig ipw0 inet 192.168.0.20 netmask 0xffffff00 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 that the necessary firmware modules are loaded 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.
