Lucent Technologies WaveLAN/IEEE 802.11 PCMCIA driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device wi"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for WaveLAN/IEEE PCCARD adapters (also known
|
|
as WaveLAN II cards). 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. Both the original
|
|
2Mbps WaveLAN/IEEE cards and the newer 6Mbps WaveLAN/IEEE Turbo
|
|
adapters are supported.
|
|
.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
|
|
.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.
|
|
.Pp
|
|
By default, the
|
|
.Nm
|
|
driver configures the WaveLAN card for ad-hoc operation. In this mode,
|
|
stations can communicate among each other without the aid of an access
|
|
point. To join a service set, the driver must be set for BSS mode using
|
|
the
|
|
.Xr wicontrol 8
|
|
utility.
|
|
.Pp
|
|

|

|
.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 "wd%d: device timeout"
|
|
The WaveLAN failed to generate an interrupt to acknowledge a transmit
|
|
command.
