NAME
wi - Lucent Hermes, and Intersil PRISM IEEE 802.11 driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
device wi
device wlan
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
if_wi_load="YES"
DESCRIPTION
The wi 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.
For more information on configuring this device, see ifconfig(8). The wi
driver supports polling(4).
wi supports station, adhoc, adhoc-demo, hostap, and monitor mode
operation. Only one virtual interface may be configured at a time. For
more information on configuring this device, see ifconfig(8).
Cards supported by the wi 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.
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.

EXAMPLES
Join an existing BSS network (ie: connect to an access point):
ifconfig wlan create wlandev wi0 inet 192.168.0.20 \
netmask 0xffffff00
Join a specific BSS network with network name "my_net":
ifconfig wlan create wlandev wi0 inet 192.168.0.20 \
netmask 0xffffff00 ssid my_net
Join a specific BSS network with WEP encryption:
ifconfig wlan create wlandev wi0 inet 192.168.0.20 \
netmask 0xffffff00 ssid my_net \
wepmode on wepkey 0x8736639624 weptxkey 1
Join a Lucent legacy demo ad-hoc network with network name "my_net":
ifconfig wlan create wlandev wi0 wlanmode ahdemo \
inet 192.168.0.20 netmask 0xffffff00 ssid my_net
Join/create an IBSS network with network name "my_net":
ifconfig wlan create wlandev wi0 wlanmode adhoc wi0 \
inet 192.168.0.22 netmask 0xffffff00 ssid my_net
Create a host-based access point (Prism only):
ifconfig wlan create wlandev wi0 wlanmode hostap \
inet 192.168.0.10 netmask 0xffffff00 ssid my_ap
Create a host-based access point with WEP enabled (Prism only) and plumb
it into bridge to fxp0:
ifconfig wlan0 create wlandev wi0 wlanmode hostap \
inet 192.168.0.10 netmask 0xffffff00 ssid my_ap \
wepmode on wepkey 0x1234567890 weptxkey 1
ifconfig bridge0 create
ifconfig bridge0 addm wlan0 addm fxp0 up
This will give you the same functionality as an access point.
DIAGNOSTICS
wi%d: init failed The WaveLAN card failed to become ready after an
initialization command was issued.
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.
wi%d: device timeout The WaveLAN card failed to generate an interrupt to
acknowledge a transmit command.

HISTORY
The wi device driver first appeared in FreeBSD 3.0.
AUTHORS
The original wi driver was written by Bill Paul <wpaul@ctr.columbia.edu>.
This man page comes from OpenBSD.
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.
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.
Lucent cards prior to firmware version 6.0.6 do not implement IBSS mode
and are not supported.
Prior versions of wi supported Symbol firmware. That support has been
removed due to persistent problems with this firmware as well as getting
proper documentation on this firmware.
Hermes 2 and Hermes 3 chips are not supported by this driver.
Here's the above requirements in the form of a table
Firmware Minimum WPA Host AP Adhoc/IBSS
Prism II/2.5 0.8.0 1.7.0 1.3.4 1.3.1
Prism 3 0.8.0 1.7.0 1.4.9 1.3.1
Hermes 6.0.6 none none 6.0.6
Symbol none none none none
BUGS
Not all the new messages are documented here, and many of them are
indications of transient errors that are not indications of serious
problems.
