|
|
|
|
The
|
|
|
|
.Nm
|
2002-05-02 22:51:40 +00:00
|
|
|
driver provides support for wireless network adapters based around
|
|
|
|
the Lucent Hermes, Intersil PRISM-II, Intersil PRISM-2.5, and Symbol
|
|
|
|
Spectrum24 chipsets.
|
|
|
|
All four chipsets provide a similar interface to the driver.
|
|
|
|
.Pp
|
|
|
|
All host/device interaction is via programmed I/O.
|
|
|
|
Supported features include 802.11 and 802.3 frames, power management, BSS,
|
2002-05-04 04:59:20 +00:00
|
|
|
IBSS, WDS and old-style Lucent ad-hoc operation modes.
|
2002-05-02 22:51:40 +00:00
|
|
|
Cards based on the Intersil PRISM-II and PRISM-2.5 chips also support a
|
|
|
|
host-based access point mode which allows a card to act as a normal access
|
|
|
|
point (with some assistance from the
|
1999-05-05 07:37:11 +00:00
|
|
|
.Nm
|
2002-05-02 22:51:40 +00:00
|
|
|
driver).
|
|
|
|
The Lucent Hermes and Symbol Spectrum24 chipsets do not contain this
|
|
|
|
functionality.
|
2002-05-03 18:11:17 +00:00
|
|
|
PRISM-II and PRISM-2.5 chips do not support the WDS functionality.
|
2002-05-02 22:51:40 +00:00
|
|
|
.Pp
|
2000-03-02 14:54:02 +00:00
|
|
|
The
|
1999-05-05 07:37:11 +00:00
|
|
|
.Nm
|
|
|
|
driver encapsulates all IP and ARP traffic as 802.11 frames, however
|
2000-03-02 14:54:02 +00:00
|
|
|
it can receive either 802.11 or 802.3 frames.
|
2002-05-02 22:51:40 +00:00
|
|
|
Transmit speed is selectable between 1Mbps fixed, 2Mbps fixed, 2Mbps
|
|
|
|
with auto fallback, 5.5Mbps, 8Mbps, or 11Mbps depending on your hardware.
|
|
|
|
The Lucent WaveLAN/IEEE Silver and Gold cards as well as the Intersil
|
|
|
|
and Symbol cards have support for WEP encryption.
|
|
|
|
The WaveLAN Gold as well as newer Intersil and Symbol cards support
|
|
|
|
104bit keys, the others only accept 40bit keys.
|
|
|
|
The Lucent WaveLAN/IEEE Bronze cards do not support WEP at all.
|
|
|
|
To enable encryption, use the
|
|
|
|
.Xr wicontrol 8
|
2002-05-03 05:39:16 +00:00
|
|
|
utility to set your keys, or use
|
|
|
|
.Xr ifconfig 8
|
|
|
|
as shown below.
|
1999-05-05 07:37:11 +00:00
|
|
|
.Pp
|
|
|
|
By default, the
|
|
|
|
.Nm
|
2002-05-02 22:51:40 +00:00
|
|
|
driver configures the card for BSS operation (aka infrastructure
|
|
|
|
mode).
|
|
|
|
This mode requires the use of an access point (base station).
|
|
|
|
.Pp
|
|
|
|
The
|
|
|
|
.Nm
|
2002-05-04 04:59:20 +00:00
|
|
|
driver also supports an point-to-point mode where the ssid is
|
|
|
|
ignored and stations can communicate amongst themselves without the
|
|
|
|
aid of an access point.
|
|
|
|
Note that there are two possible point-to-point modes.
|
2002-05-02 22:51:40 +00:00
|
|
|
One mode, referred to as
|
2002-05-30 10:33:19 +00:00
|
|
|
.Dq "ad-hoc demo mode" ,
|
2002-05-04 04:59:20 +00:00
|
|
|
or
|
2002-05-30 10:33:19 +00:00
|
|
|
.Dq "legacy Lucent ad-hoc mode" ,
|
2002-05-02 22:51:40 +00:00
|
|
|
predates the IEEE 802.11 specification and so may not interoperate
|
2002-05-04 04:59:20 +00:00
|
|
|
with cards from different vendors.
|
|
|
|
The standardized point-to-point mode, is called IBSS (or confusingly
|
|
|
|
just ad-hoc mode), but is not supported by cards with very old
|
|
|
|
firmware revisions.
|
|
|
|
If your cards supports IBSS mode, it is recommended that you use it in
|
|
|
|
preference to the
|
2002-05-30 10:33:19 +00:00
|
|
|
.Dq "ad-hoc demo mode"
|
2002-05-04 04:59:20 +00:00
|
|
|
in new installations.
|
2002-05-02 22:51:40 +00:00
|
|
|
.Pp
|
|
|
|
Cards based on the Intersil PRISM-II and PRISM-2.5 chips also
|
|
|
|
have a host-based access point mode which allows the card to
|
|
|
|
act as an access point (base station).
|
2002-05-04 04:59:20 +00:00
|
|
|
Access points are different than operating in IBSS mode.
|
|
|
|
They operate in BSS mode.
|
|
|
|
They allow for easier roaming and bridge all ethernet traffic such
|
|
|
|
that machines connected via an access point appear to be on the local
|
|
|
|
ethernet segment.

.Pp
|
|
|
|
Cards supported by the
|
|
|
|
.Nm
|
|
|
|
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.
|
2002-05-30 10:33:19 +00:00
|
|
|
.Pp
|
2002-05-02 22:51:40 +00:00
|
|
|
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.

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.
|
2002-05-03 18:11:17 +00:00
|
|
|
Different regulatory domains have different default channels.
