WaveLAN/IEEE and PRISM-II 802.11 PCMCIA wireless network driver
|
|
.Sh SYNOPSIS
|
|
.Cd "wi* at pcmcia? function ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for Lucent Technologies WaveLAN/IEEE PCCARD adapters
|
|
(also known as WaveLAN II cards) and various PCCARD adapters which use
|
|
Intersil PRISM-II chipsets.
|
|
Note that while Lucent sells both ISA and PCMCIA WaveLAN/IEEE devices,
|
|
the ISA product is actually a PCMCIA card in an ISA to PCMCIA bridge adapter.
|
|
Consequently, the
|
|
.Nm
|
|
driver is required for both the ISA and PCMCIA NICs.
|
|
Also note that some of the PRISM-II adapters works only at 3.3V, hence
|
|
.Xr cardbus 4
|
|
support is required for those cards to set VCC correctly,
|
|
even they are 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. The Silver and the Gold cards of the
|
|
WaveLAN/IEEE also support WEP. Unlike the other IEEE 802.11 network cards,
|
|
the WaveLAN Gold cards accept 104 bits key (13 characters) for WEP
|
|
encryption. The Intersil PRISM-II controller supports WEP as well.
|
|
.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 or 2Mbps with auto fallback.
|
|
For WaveLAN/IEEE Turbo adapters, speeds up to 6Mbps are available.
|
|
For WaveLAN/IEEE Turbo 11Mbps adapters and PRISM-II adapters, speeds up to
|
|
11Mbps are available.
|
|
.Pp
|
|
By default, the
|
|
.Nm
|
|
driver configures the WaveLAN card for special ad-hoc operation.
|
|
In this mode, the nwid is ignored and
|
|
stations can communicate among each other without the aid of an access
|
|
point.
|
|
Note that this mode is out of IEEE 802.11 specification and the driver
|
|
cannot interoperate with other cards.
|
|
To join a service set, the driver must be set for BSS mode using the
|
|
.Xr ifconfig 8
|
|
or
|
|
.Xr wiconfig 8
|
|
utility.
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8
|
|
and
|
|
.Xr ifmedia 4 .

The original PRISM-I chipset is supported by the

|
|
driver.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "wi%d: init failed"
|
|
The WaveLAN 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.
|
|
One reason can be that the board is mis-configured, see
|
|
.Xr wiconfig 8 .
|
|
.El
|
|
.Sh BUGS
|
|
The IBSS mode is not supported.
|
|
The execution of
|
|
.Xr wiconfig 8
|
|
during the interface is down produces some error messages.
