.Sh NAME
|
|
.Nm wi
|
|
.Nd "Lucent Hermes, and Intersil PRISM IEEE 802.11 driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device wi"
|
|
.Cd "device wlan"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_wi_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for 802.11b wireless network adapters based around
|
|
the Lucent Hermes, Intersil PRISM-II, Intersil PRISM-2.5, and Intersil
|
|
Prism-3 chipsets.
|
|
All chipsets provide a similar interface to the driver.
|
|
Only the Intersil chipsets support access point operation or WPA.
|
|
Very old versions of firmware are not supported at all.
|
|
Older versions of the firmware that are supported may severely limit
|
|
the ability to use these cards in newer networks.
|
|
Only relatively recent versions of Intersil firmware supports WPA.
|
|
See CAVEATS for details.
|
|
All host/device interaction is via programmed I/O, even on those cards
|
|
that support a DMA interface.
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .
|

|
|

supports
|
|
.Cm station ,
|
|
.Cm adhoc ,
|
|
.Cm adhoc-demo ,
|
|
.Cm hostap ,
|
|
and
|
|
.Cm monitor
|
|
mode operation.
|
|
Only one
|
|
virtual interface may be configured at a time.
|
|
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.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
The following cards are among those supported by the
|
|
.Nm
|
|
driver:

|
|
The WaveLAN card failed to become ready after an initialization command

|
|
.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.
|
|
This can also be an indication of an incorrectly configured interrupt.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver first appeared in
|
|
.Fx 3.0 .
|
|
.Sh AUTHORS
|
|
The original
|
|
.Nm
|
|
driver was written by
|
|
.An Bill Paul Aq Mt wpaul@ctr.columbia.edu .
|
|
This man page comes from
|
|
.Ox .
|
|
.Sh CAVEATS
|
|
The driver will reject devices with old firmware to
|
|
avoid dealing with numerous defects.
|
|
Unfortunately the driver does not support downloading new firmware
|
|
to the card so if new firmware is needed users will have to boot
|
|
a different system to accomplish this.
|
|
.Pp
|
|
Intersil Prism cards must have firmware versions 0.8.0 or later and
|
|
version 1.7.0 or later are required to support functionality such as WPA.
|
|
Some users of Prism-II and 2.5 based cards report that station firmware
|
|
version 1.3.4 works better for them in hostap than 1.4.9.
|
|
Older versions of the Prism station firmware have a number of issues
|
|
with hostap mode.
|
|
The IBSS/adhoc mode appears to work well on station firmware 1.3.1 and
|
|
later.
|
|
The IBSS/adhoc mode appears to have problems for some people with
|
|
older versions of station firmware.
|
|
.Pp
|
|
Lucent cards prior to firmware version 6.0.6 do not implement IBSS
|
|
mode and are not supported.
|
|
.Pp
|
|
Prior versions of
|
|
.Nm
|
|
supported Symbol firmware.
|
|
That support has been removed due to persistent problems with this
|
|
firmware as well as getting proper documentation on this firmware.
|
|
.Pp
|
|
Hermes 2 and Hermes 3 chips are not supported by this driver.
