.Sh NAME
.Nm wi
.Nd WaveLAN/IEEE and PRISM-II 802.11DS wireless network driver
.Sh SYNOPSIS
.Cd "wi* at pci? dev ? function ?"
.Cd "wi* at pcmcia? function ?"
.Cd "wi* at macobio?"
.Sh DESCRIPTION
The
.Nm
driver provides support for PCMCIA adapters based on the Lucent Technologies
WaveLAN/IEEE (aka WaveLAN II) and Intersil PRISM-II chipsets.
The compatible cards supported are:
.Pp
.Bl -tag -width -offset indent -compact
.It 3Com AirConnect Wireless LAN
.It Corega Wireless LAN PCC-11
.It Corega Wireless LAN PCCA-11
.It Intersil Prism II
.It Samsung MagicLAN SWL-2000N
.It SMC 2632 EZ Connect Wireless PC Card
.It NANOSPEED ROOT-RZ2000 WLAN Card
.It XI300 Wireless LAN
.It Compaq Agency NC5004 Wireless Card
.It Contec FLEXLAN/FX-DS110-PCC
.It TDK LAK-CD011WL
.It NEC Wireless Card CMZ-RT-WP
.It NTT-ME 11Mbps Wireless LAN PC Card
.It Addtron AWP-100
.It Cabletron RoamAbout
.It I-O DATA WN-B11/PCM
.It Linksys WPC11
.El
.Pp
Note that while Lucent sells PCI, ISA and PCMCIA WaveLAN/IEEE
devices, the PCI and ISA products are actually a PCMCIA card in a
PCMCIA bridge adapter. Consequently, the
.Nm
driver is required for PCI, ISA and PCMCIA NICs. The original
WaveLAN/IEEE cards (2Mbps), the WaveLAN/IEEE Turbo (6Mbps), the
WaveLAN/IEEE Bronze Turbo (8Mbps), and the
WaveLAN/IEEE Silver/Gold (11Mbps) adapters are supported.
.Pp
Unlike the Lucent devices, several vendors sell PCI adapters built
around the PLX Technology 9050 or 9052 chip.
These adapters are dumb PCMCIA bridges that do not attach as a
normal PCMCIA bus.
Instead they appear to the host as a normal PCI device and do
not require any PCMCIA support.
The following such bridges are supported or expected to work:
.Pp
.Bl -tag -width -offset indent -compact
.It 3Com AirConnect 3CRWE777A
.It Global Sun Technology GL24110P02
.It LinkSys WDT11 (a rebadged GL24110P02)
.It Global Sun Technology GL24110P (untested)
.It Eumitcom WL11000P (untested)
.El
.Pp
Also note that some of the PRISM-II adapters only work at 3.3V, hence
.Xr cardbus 4
support is required for those cards to set VCC correctly, even
though they are really 16bit cards.
.Pp
The core of the WaveLAN/IEEE is the Lucent Hermes controller. All
host/device interaction is via programmed I/O with the Hermes.
The Hermes supports 802.11 and 802.3 frames, power management, BSS,
WDS and ad-hoc operation modes.
.Pp
The
.Nm
driver encapsulates all IP and ARP traffic as 802.11 frames, however
it can receive either 802.11 or 802.3 frames.
Transmit speed is selectable between 1Mbps fixed, 2Mbps fixed, 2Mbps
with auto fallback, 6Mbps, 8Mbps, or 11Mbps depending on your hardware
(see above).
The Lucent WaveLAN/IEEE Silver and Gold cards as well as the Intersil
PRISM-II cards have support for WEP encryption.
The WaveLAN Gold cards support 104bit keys, the others only accept
40bit keys.
The Lucent Bronze cards do not support WEP.
To enable the encryption, use the
.Xr wicontrol 8
utility to set your keys.
.Pp
By default, the
.Nm
driver configures the WaveLAN card for BSS operation (aka infrastructure
mode).
This mode requires the use of an access point (base station).
.br
The
.Nm
driver also supports an ad-hoc (point-to-point) mode where
the nwid is ignored and stations can communicate among
each other without the aid of an access point.
Note that this mode is not in the IEEE 802.11 specification and the
driver may not be able to interoperate with other vendor's cards
while in ad-hoc mode.
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
.Sh DIAGNOSTICS
.Bl -diag
.It "wi%d: init failed"
The WaveLAN card failed to come ready after an initialization command
was issued.
.It "wi%d: failed to allocate %d bytes on NIC"
The driver was unable to allocate memory for transmit frames in the
NIC's on-board RAM.
.It "wi%d: device timeout"
The WaveLAN failed to generate an interrupt to acknowledge a transmit
command.

.Sh HISTORY
The
.Nm
device driver first appeared in
.Fx 3.0 .
.Ox
support was added in
.Ox 2.6 .
.Sh AUTHORS
The
.Nm
driver was written by Bill Paul <wpaul@ctr.columbia.edu> and ported to
.Ox
by Niklas Hallqvist <niklas@appli.se>.
.Sh CAVEATS
The original Lucent WaveLAN cards usually default to channel 3;
newer cards use channel 10 by default.
Non-Lucent cards vary, for instance the Addtron cards use channel
11 by default.
See
.Xr wicontrol 8
for information on how to change the channel.
