WaveLAN/IEEE and PRISM-II 802.11 wireless network driver
|
|
.Sh SYNOPSIS
|
|
.Cd "wi* at pcmcia? function ?"
|
|
.Cd "wi* at pci? dev ? function ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for Lucent Technologies WaveLAN/IEEE PCCARD adapters
|
|
(also known as WaveLAN II cards) and various PCI/MiniPCI/PCCARD adapters which use
|
|
Intersil PRISM-II and PRISM-2.5 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 though they are 16-bit 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 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
|
|
The
|
|
.Nm
|
|
driver supports configuration of Lucent cards 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 specific
|
|
to Lucent chips, and not in the IEEE 802.11 specification. Due to changes
|
|
in the implementation of this special ad-hoc mode, Lucent-based cards with
|
|
different firmware revisions may not interoperate in this mode. This mode
|
|
is no longer the default and must be selected using the
|
|
.Xr ifconfig 8
|
|
.Pq media option Dq adhoc,flag0
|
|
utility.
|
|
.Pp
|
|
Recent versions of Lucent and PRISM-II firmware support IBSS creation.
|
|
IBSS is the standard IEEE 802.11 ad-hoc mode. In this mode, the nwid
|
|
should be specified. At least one node must be able to create IBSS.
|
|
The IBSS mode is enabled by
|
|
.Dq adhoc
|
|
or
|
|
.Dq ibss
|
|
media option.
|
|
IBSS creation is automatically enabled if supported.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver defaults to infrastructure mode (i.e., using an access point).
|
|
.Pp
|
|
Recent versions of PRISM-II firmware support operating as an 802.11
|
|
Access Point. In this mode, the Access Point station should set the
|
|
nwid. This will create a standard 802.11 network, and the Access Point
|
|
station will show up in an Access Point scan. This mode is enabled
|
|
using the
|
|
.Dq hostap
|
|
media option.
|
|
.Pp
|
|

|
|

|
|
