Bring the wi man page into the 21st centry. This man page is based
heavily on OpenBSD's wi man page, with OpenBSDisms replaced by FreeBSDisms. I also added a note about where the man page came from. I hope that I've not broken anything that ru cleaned up. We now run this through tbl, but that appears to be automatic. Obtained From: OpenBSD

.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
+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,
+IBSS, WDS and ad-hoc operation modes.
+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
.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.
+driver).
+The Lucent Hermes and Symbol Spectrum24 chipsets do not contain this
+functionality.
+.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.
+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
+utility to set your keys.
.Pp
By default, the
.Nm
-driver configures the WaveLAN card for BSS operation.
+driver configures the card for BSS operation (aka infrastructure
+mode).
+This mode requires the use of an access point (base station).
+.Pp
+The
+.Nm
+driver also supports an ad-hoc (point-to-point) mode where
+the nwid is ignored and stations can communicate amongst
+themselves without the aid of an access point.
+Note that there are two possible ad-hoc modes.
+One mode, referred to as
+.Dq ad-hoc demo mode ,
+predates the IEEE 802.11 specification and so may not interoperate
+with cards from other vendors.
+The standardized ad-hoc mode, also know as IBSS mode, is not
+supported by cards with very old firmware revisions.
+.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).
.Pp
For more information on configuring this device, see
+.Xr ifconfig 8 .
+.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.
+.br
+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 following cards are among those supported to by
