37.Sh NAME
38.Nm wi
39.Nd "Lucent Hermes, Intersil PRISM and Spectrum24 IEEE 802.11 driver"
40.Sh SYNOPSIS
41.Cd "device wi"
42.Cd "device wlan"
43.Sh DESCRIPTION
44The
45.Nm
46driver provides support for wireless network adapters based around
47the Lucent Hermes, Intersil PRISM-II, Intersil PRISM-2.5, Intersil
48Prism-3, and Symbol Spectrum24 chipsets.
49All five chipsets provide a similar interface to the driver.
50.Pp
51Supported features include 802.11 and 802.3 frames, power management, BSS,
52IBSS, WDS and old-style Lucent ad-hoc operation modes.
53Cards based on the Intersil PRISM chips also support a host-based
54access point mode which allows a card to act as a normal access point
55(with some assistance from the
56.Nm
57driver).
58The Lucent Hermes and Symbol Spectrum24 chipsets do not contain this
59functionality.
60The PRISM family of chips do not support the WDS functionality.
61All host/device interaction is via programmed I/O, even on those cards
62that support a DMA interface.
63.Pp
64The
65.Nm
66driver encapsulates all IP and ARP traffic as 802.11 frames, however
67it can receive either 802.11 or 802.3 frames.
68Transmit speed is selectable between 1Mbps, 2Mbps, 5.5 Mbps and 11Mbps
69depending on your hardware.
70Most hardware supports 11Mbps where the signal quality allows, but
71falls back to slower speeds when it does not.
72Except for the Lucent WaveLAN Bronze cards, all cards supported by the
73.Nm
74driver support WEP for encryption.
75To enable encryption, use
76.Xr ifconfig 8
77as shown below.
78.Pp
79By default, the
80.Nm
81driver configures the card for BSS operation (aka infrastructure
82mode).
83This mode requires the use of an access point (base station).
84.Pp
85The
86.Nm
87driver also supports a point-to-point mode
88where stations can communicate amongst themselves without the
89aid of an access point.
90Note that there are two possible point-to-point modes.
91One mode, referred to as
92.Dq "ad-hoc demo mode" ,
93or
94.Dq "legacy Lucent ad-hoc mode" ,
95predates the IEEE 802.11 specification and so may not interoperate
96with cards from different vendors.
97The standardized point-to-point mode is called IBSS (or confusingly
98just ad-hoc mode), but is not supported by cards with very old
99firmware revisions.
100If your cards supports IBSS mode, it is recommended that you use it in
101preference to the
102.Dq "ad-hoc demo mode"
103in new installations.
104.Pp
105Cards supported by the driver based on the Intersil PRISM family of chips also
106have a host-based access point mode which allows the card to
107act as an access point (base station).
108Access points are different than operating in IBSS mode.
109They operate in BSS mode.
110They allow for easier roaming and bridge all ethernet traffic such
111that machines connected via an access point appear to be on the local
112ethernet segment.
113.Pp
114For more information on configuring this device, see
115.Xr ifconfig 8 .
116.Pp
117Cards supported by the
118.Nm
119driver come in a variety of packages, though the most common
120are of the PCMCIA type.
121In many cases, the PCI version of a wireless card is simply
122a PCMCIA card bundled with a PCI adapter.
123The PCI adapters come in two flavors: true PCMCIA bridges and
124dumb PCMCIA bridges.
125A true PCMCIA bridge (such as those sold by Lucent) will attach
126as a real PCMCIA controller.
127The wireless card will then attach to the PCMCIA bus.
128Wireless cards in PCMCIA slots may be inserted and ejected on the fly.
129.Pp
130A dumb bridge, on the other hand, does not show up as a true PCMCIA bus.
131The wireless card will simply appear to the host as a normal PCI
132device and will not require any PCMCIA support.
133Cards in this type of adapter should only be removed when the
134machine is powered down.
135.Pp

137.Nm
