- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing the initial work here. One thing I changed was to have the attach and detach routines work like the PCI drivers, which means that in theory you should be able to load and unload the driver like the PCI NIC drivers, however the pccard support for this hasn't settled down yet so it doesn't quite work. Once the pccard work is done, I'll have to revisit this. - Add device wi0 to PCCARD. If we're lucky, people should be able to install via their WaveLAN cards now. - Add support for signal strength caching. The wicontrol utility has also been updated to allow zeroing and displaying the signal strength cache. - Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko. Currently this module is only built for the i386 platform, though once the pccard stuff is done it should be able to work on the alpha too. (Theoretically you should be able to plug one of the WaveLAN/IEEE ISA cards into an alpha with an ISA slot, but we'll see how that turns out. - Update LINT to use only device wi0. There is no true ISA version of the WaveLAN/IEEE so we'll never use an ISA attachment. - Update files.i386 so that if_wi is dependent on card.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command controls the operation of WaveLAN/IEEE wireless networking
|
|
devices via the
|
|
.Xr wi 4
|
|
driver. Most of the parameters that can be changed relate to the
|
|
IEEE 802.11 protocol which the WaveLAN implements. This includes
|
|
the station name, whether the station is operating in ad-hoc (point
|
|
to point) or BSS (service set) mode, and the network name of a service
|
|
set to join (IBSS) if BSS mode is enabled. The
|
|
.Nm
|
|
command can also be used to view the current settings of these parameters
|
|
and to dump out the values of the card's statistics counters.
|
|
.Pp
|
|
The
|
|
.Ar iface
|
|
argument given to
|
|
.Nm
|
|
should be the logical interface name associated with the WaveLAN/IEEE
|
|
device (wi0, wi1, etc...).
|
|
.Sh OPTIONS
|
|
The options are as follows:
|
|
.Bl -tag -width Fl
|
|
.It Fl i Ar iface Op Fl o
|
|
Display the current settings of the specified WaveLAN/IEEE interface.
|
|
This retrieves the current card settings from the driver and prints them
|
|
out. Using the additional
|
|
.Fl o
|
|
flag will cause
|
|
.Nm
|
|
to print out the statistics counters instead of the card settings.
|
|
.It Fl i Ar iface Fl t Ar tx rate
|
|
Set the transmit rate of the specified interface. The legal values
|
|
for the transmit rate vary depending on whether the interface is a
|
|
standard WaveLAN/IEEE or a WaveLAN/IEEE Turbo adapter. The standard
|
|
NICs support a maximum transmit rate of 2Mbps while the turbo NICs
|
|
support a maximum speed of 6Mbps. The following table shows the
|
|
legal transmit rate settings and the corresponding transmit speeds:
|
|

2 Fixed Standard (2Mbps)
|
|
3 Auto Rate Select (High)
|
|
4 Fixed Medium (4Mbps)
|
|
5 Fixed High (6Mbps)
|
|
6 Auto Rate Select (Standard)
|
|
7 Auto Rate Select (Medium)
|
|
.El
|
|
.Ed
|
|
.Pp
|
|
The standard NICs support only settings 1 through 3. Turbo NICs support
|
|
all the above listed speed settings.
|
|
The default driver setting is 3 (auto rate select).
|
|
.It Fl i Ar iface Fl n Ar network name
|
|
Set the name of the service set (IBSS) that this station wishes to
|
|
join. The
|
|
.Ar network name
|
|
can be any text string up to 30 characters in length. The default name
|
|
is the string "ANY" which should allow the station to connect to the first
|
|
available access point. The interface should be set for BSS mode using
|
|
the
|
|
.Fl p
|
|
flag in order for this to work.
|
|
.Pp
|
|
Note: the WaveLAN manual indicates that an empty string will allow the
|
|
host to connect to any access point, however I have also seen a reference
|
|
in another driver which indicates that the "ANY" string works as well.
|
|
.It Fl i Ar iface Fl s Ar station name
|
|
Sets the
|
|
.Ar station name
|
|
for the specified interface. The
|
|
.Ar station name
|
|
is used for diagnostic purposes. The Lucent WaveMANAGER software can
|
|
poll the names of remote hosts.
|
|
.It Fl i Ar iface Fl c Ar 0|1
|
|
Allow the station to create a service set (IBSS). Permitted values
|
|
are 0 (don't create IBSS) and 1 (enable creation of IBSS). The default
|
|
is 0.
|
|
.Pp
|
|
Note: this option is provided for experimental purposes only: enabling
|
|
the creation of an IBSS on a host system doesn't appear to actually work.
|
|
.It Fl i Ar iface Fl q Ar SSID
|
|
Specify the name of an IBSS (SSID) to create on a given interface.
|
|
The
|
|
.Ar SSID
|
|
can be any text string up to 30 characters long.
|
|
.Pp
|
|
Note: this option is provided for experimental purposes only: enabling
|
|
the creation of an IBSS on a host system doesn't appear to actually work.
|
|
.It Fl i Ar iface Fl p Ar port type
|
|
Set the
|
|
.Ar port type
|
|
for a specified interface. The legal values for
|
|
.Ar port type
|
|
are 1 (BSS mode) and 3 (ad-hoc) mode. In ad-hoc mode, the station can
|
|
communicate directly with any other stations within direct radio range
|
|
(provided that they are also operating in ad-hoc mode). In BSS mode,
|
|
hosts must associate with a service set controlled by an access point,
|
|
which relays traffic between end stations. The default setting is 3
|
|
(ad-hoc mode).
|
|
.It Fl i Ar iface Fl a Ar access_point_density
|
|
Specify the
|
|
.Ar access point density
|
|
for a given interface. Legal values are 1 (low), 2 (medium) and 3 (high).
|
|
This setting influences some of the radio modem threshold settings.
|
|
.It Fl i Ar iface Fl m Ar mac address
|
|
Set the station address for the specified interface. The
|
|
.Ar mac address
|
|
is specified as a series of six hexadecimal values separated by colons,
|
|
e.g.: 00:60:1d:12:34:56. This programs the new address into the card
|
|
and updates the interface as well.
|
|
.It Fl i Ar iface Fl d Ar max_data_length
|
|
Set the maximum receive and transmit frame size for a specified interface.
|
|
The
|
|
.Ar max data length
|
|
can be any number from 350 to 2304. The default is 2304.
|
|
.It Fl i Ar iface Fl r Ar RTS threshold
|
|
Set the RTS/CTS threshold for a given interface. This controls the
|
|
number of bytes used for the RTS/CTS handshake boundary. The
|
|
.Ar RTS threshold
|
|
can be any value between 0 and 2047. The default is 2347.
|
|
.It Fl i Ar iface Fl f Ar frequency
|
|
Set the radio frequency of a given interface. The
|
|
.Ar frequency
|
|
should be specified as a channel ID as shown in the table below. The
|
|
list of available frequencies is dependent on radio regulations specified
|
|
by regional authorities. Recognized regulatory authorities include
|
|
the FCC (United States), ETSI (Europe), France and Japan. Frequencies
|
|
in the table are specified in Mhz.

If an illegal channel is specified, the
|
|
NIC will revert to its default channel. For NICs sold in the United States
|
|
and Europe, the default channel is 3. For NICs sold in France, the default
|
|
channel is 11. For NICs sold in Japan, the only available channel is 14.
|
|
Note that two stations must be set to the same channel in order to
|
|
communicate.
|
|
.It Fl i Ar iface Fl P Ar 0|1
|
|
Enable or disable power management on a given interface. Enabling
|
|
power management uses an alternating sleep/wake protocol to help
|
|
conserve power on mobile stations, at the cost of some increased
|
|
receive latency. Power management is off by default. Note that power
|
|
management requires the cooperation of an access point in order to
|
|
function; it is not functional in ad-hoc mode. Also, power management
|
|
is only implemented in Lucent WavePOINT firmware version 2.03 or
|
|
later, and in WaveLAN PCMCIA adapter firmware 2.00 or later. Older
|
|
revisions will silently ignore the power management setting. Legal
|
|
values for this parameter are 0 (off) and 1 (on).
|
|
.It Fl i Ar iface Fl S Ar max_sleep_interval
|
|
Specify the sleep interval to use when power management is enabled.
|
|
The
|
|
.Are max sleep interval
|
|
is specified in milliseconds. The default is 100.
|
|
.It Fl i Ar iface Fl Z
|
|
Clear the signal strength cache maintained internally by the
|
|
.Nm wi
|
|
driver.
|
|
.It Fl i Ar iface Fl C
|
|
Display the cached signal strength information maintained by the
|
|
.Nm wi
|
|
driver. The driver retains information about signal strength and
|
|
noise level for packets received from different hosts. The signal
|
|
strength and noise level values are displayed in units of dBms.
|
|
The signal quality values is produced by subtracting the noise level
|
|
from the signal strength (i.e. less noise and better signal yields
|
|
better signal quality).
