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 ipwfw device pci device wlan device firmware

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

if_ipw_load="YES"

In both cases, place the following line in loader.conf5 to acknowledge the firmware license (see below):

legal.intel_ipw.license_ack=1

DESCRIPTION

The ifconfig driver provides support for the Intel PRO/Wireless 2100 MiniPCI network adapter. ifconfig supports station adhoc and monitor mode operation. Only one virtual interface may be configured at any time. For more information on configuring this device, see ifconfig(8).

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.conf5:

"legal.intel_ipw.license_ack=1"

FILES

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

ifconfig firmware license

EXAMPLES

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

ifconfig wlan create wlandev ipw0 inet 192.168.0.20 \
    netmask 0xffffff00

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.
