WI(4)		       FreeBSD Kernel Interfaces Manual			 WI(4)

NAME
     wi	-- Lucent Hermes, and Intersil PRISM IEEE 802.11 driver

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

	   device wi
	   device wlan

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_wi_load="YES"

DESCRIPTION
     The wi driver provides support for	802.11b	wireless network adapters
     based around the Lucent Hermes, Intersil PRISM-II,	Intersil PRISM-2.5,
     and Intersil Prism-3 chipsets.  All chipsets provide a similar interface
     to	the driver.  Only the Intersil chipsets	support	access point operation
     or	WPA.  Very old versions	of firmware are	not supported at all.  Older
     versions of the firmware that are supported may severely limit the	abil-
     ity to use	these cards in newer networks.	Only relatively	recent ver-
     sions of Intersil firmware	supports WPA.  See CAVEATS for details.	 All
     host/device interaction is	via programmed I/O, even on those cards	that
     support a DMA interface.

     For more information on configuring this device, see ifconfig(8).

     wi	supports station, adhoc, adhoc-demo, hostap, and monitor mode opera-
     tion.  Only one virtual interface may be configured at a time.  For more
     information on configuring	this device, see ifconfig(8).

     Cards supported by	the wi driver come in a	variety	of packages, though
     the most common are of the	PCMCIA type.  In many cases, the PCI version
     of	a wireless card	is simply a PCMCIA card	bundled	with a PCI adapter.
     The PCI adapters come in two flavors: true	PCMCIA bridges and dumb	PCMCIA
     bridges.  A true PCMCIA bridge (such as those sold	by Lucent) will	attach
     as	a real PCMCIA controller.  The wireless	card will then attach to the
     PCMCIA bus.  Wireless cards in PCMCIA slots may be	inserted and ejected
     on	the fly.

     A dumb bridge, on the other hand, does not	show up	as a true PCMCIA bus.
     The wireless card will simply appear to the host as a normal PCI device
     and will not require any PCMCIA support.  Cards in	this type of adapter
     should only be removed when the machine is	powered	down.

     Several vendors sell PCI adapters built around the	PLX Technology 9050 or
     9052 chip.	 The following such adapters are supported or expected to
     work:

     3Com AirConnect 3CRWE777A (3.3V)
     Belkin F5D6000 (a rebadged	WL11000P)
     Eumitcom WL11000P
     Global Sun	Technology GL24110P (untested)
     Global Sun	Technology GL24110P02
     LinkSys WDT11 (a rebadged GL24110P02)
     Netgear MA301
     US	Robotics 2415 (rebadged	WL11000P)
     Wisecom Wireless LAN PCI Adapter

     The following adapters have the same model	numbers	as those listed	above,
     but might not work	if the actual card is after the	change away from the
     Prism family:

     DLink DWL520

EXAMPLES
     Join an existing BSS network (ie: connect to an access point):

	   ifconfig wlan create	wlandev	wi0 inet 192.168.0.20 \
	       netmask 0xffffff00

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

	   ifconfig wlan create	wlandev	wi0 inet 192.168.0.20 \
	       netmask 0xffffff00 ssid my_net

     Join a specific BSS network with WEP encryption:

	   ifconfig wlan create	wlandev	wi0 inet 192.168.0.20 \
	       netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x8736639624 weptxkey 1

     Join a Lucent legacy demo ad-hoc network with network name	``my_net'':

	   ifconfig wlan create	wlandev	wi0 wlanmode ahdemo \
	       inet 192.168.0.20 netmask 0xffffff00 ssid my_net

     Join/create an IBSS network with network name ``my_net'':

	   ifconfig wlan create	wlandev	wi0 wlanmode adhoc wi0 \
	       inet 192.168.0.22 netmask 0xffffff00 ssid my_net

     Create a host-based access	point (Prism only):

	   ifconfig wlan create	wlandev	wi0 wlanmode hostap \
	       inet 192.168.0.10 netmask 0xffffff00 ssid my_ap

     Create a host-based access	point with WEP enabled (Prism only) and	plumb
     it	into bridge to fxp0:

	   ifconfig wlan0 create wlandev wi0 wlanmode hostap \
	       inet 192.168.0.10 netmask 0xffffff00 ssid my_ap \
	       wepmode on wepkey 0x1234567890 weptxkey 1
	   ifconfig bridge0 create
	   ifconfig bridge0 addm wlan0 addm fxp0 up

     This will give you	the same functionality as an access point.

DIAGNOSTICS
     wi%d: init	failed	The WaveLAN card failed	to become ready	after an ini-
     tialization command was issued.

     wi%d: failed to allocate %d bytes on NIC  The driver was unable to	allo-
     cate memory for transmit frames in	the NIC's on-board RAM.	 This can also
     be	an indication of an incorrectly	configured interrupt.

     wi%d: device timeout  The WaveLAN card failed to generate an interrupt to
     acknowledge a transmit command.

HISTORY
     The wi device driver first	appeared in FreeBSD 3.0.

AUTHORS
     The original wi driver was	written	by Bill	Paul <wpaul@ctr.columbia.edu>.
     This man page comes from OpenBSD.

CAVEATS
     The driver	will reject devices with old firmware to avoid dealing with
     numerous defects.	Unfortunately the driver does not support downloading
     new firmware to the card so if new	firmware is needed users will have to
     boot a different system to	accomplish this.

     Intersil Prism cards must have firmware versions 0.8.0 or later and ver-
     sion 1.7.0	or later are required to support functionality such as WPA.
     Some users	of Prism-II and	2.5 based cards	report that station firmware
     version 1.3.4 works better	for them in hostap than	1.4.9.	Older versions
     of	the Prism station firmware have	a number of issues with	hostap mode.
     The IBSS/adhoc mode appears to work well on station firmware 1.3.1	and
     later.  The IBSS/adhoc mode appears to have problems for some people with
     older versions of station firmware.

     Lucent cards prior	to firmware version 6.0.6 do not implement IBSS	mode
     and are not supported.

     Prior versions of wi supported Symbol firmware.  That support has been
     removed due to persistent problems	with this firmware as well as getting
     proper documentation on this firmware.

     Hermes 2 and Hermes 3 chips are not supported by this driver.

     Here's the	above requirements in the form of a table

     Firmware	    Minimum    WPA	  Host AP    Adhoc/IBSS
     Prism II/2.5   0.8.0      1.7.0	  1.3.4	     1.3.1
     Prism 3	    0.8.0      1.7.0	  1.4.9	     1.3.1
     Hermes	    6.0.6      none	  none	     6.0.6
     Symbol	    none       none	  none	     none

BUGS
     Not all the new messages are documented here, and many of them are	indi-
     cations of	transient errors that are not indications of serious problems.
