NAME

       iwi - Intel Pro. Wireless 802.11a/b/g IPW2200B/G IPW2915A/B/G Driver

DESCRIPTION

       The   iwi  802.11b/g   wireless	NIC  driver is a multi-threaded, loadable, clonable,  GLDv3-based STREAMS driver supporting  the Data Link
       Provider Interface, dlpi(7P), on Intel Pro Wireless 2200BG 2915ABG chipset-based wireless NIC's. Driver functions include controller   ini-
       tialization, wireless 802.11b  infrastructure network connection, WEP and frame transmit and receive.

DRIVER CONFIGURATION

       The iwi driver performs auto-negotiation to determine the data rate and mode. Supported 802.11b	data rates are 1, 2, 5.5 and 11 Mbits/sec.
       Supported 802.11g data rates are 1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48 and 54 Mbits/sec.

       The iwi driver supports only BSS networks (also known as "ap" or "infrastructure" networks) and "open"(or "open-system") or "shared system"
       authentication.	Only  WEP  encryption  is  currently supported. You perform configuration and administration tasks using the dladm(1M) and
       wificonfig(1M) utilities.

NAME

     iwi -- Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 driver

SYNOPSIS

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

	   device iwi
	   device iwifw
	   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_iwi_load="YES"

     In both cases, place the following line in loader.conf(5) to acknowledge the firmware license (see below):

	   legal.intel_iwi.license_ack=1

DESCRIPTION

     The iwi driver provides support for Intel PRO/Wireless 2200BG/2915ABG MiniPCI and 2225BG PCI network adapters.  iwi 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 iwifw module to work.  For the loaded firmware to be enabled for use the license at
     /usr/share/doc/legal/intel_iwi/LICENSE must be agreed by adding the following line to loader.conf(5):

	   legal.intel_iwi.license_ack=1

FILES

     /usr/share/doc/legal/intel_iwi/LICENSE  iwi firmware license

EXAMPLES

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

	   ifconfig wlan create wlandev iwi0 inet 192.168.0.20 
	       netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig wlan create wlandev iwi0 ssid my_net up

     Join a specific BSS network with 64-bit WEP encryption:

	   ifconfig wlan create wlandev iwi0 ssid my_net 
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

     Join a specific BSS network with 128-bit WEP encryption:

	   ifconfig wlan create wlandev iwi0 wlanmode adhoc 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 crashed 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 the iwifw(4)
     firmware module is installed and the license agreement loader(8) tunable has been set.

     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.
