IPW(4)			     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 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 the Intel PRO/Wireless 2100 MiniPCI
     network adapter.  ipw supports station, adhoc, and monitor mode  operation.
     Only  one virtual interface may be configured at any time.  For more infor-
     mation 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 follow-
     ing line 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 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.
