.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...). If none is specified then wi0 is used
|
|
as default.
|
|
.Sh OPTIONS
|
|
The options are as follows:
|
|
.Bl -tag -width Fl
|
|
.It Fl i Ar iface Op Fl oa
|
|
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. Using
|
|
the additional
|
|
.Fl a
|
|
flag will cause
|
|
.Nm
|
|
to print out encryption keys as ascii characters instead of in hex.
|
|
Encryption keys are only displayed if wicontrol is run as root.
|
|
.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:
|
|
.Bl -column "TX rate " "NIC speed " -offset indent
|
|
.Em "TX rate NIC speed"
|
|
1 Fixed Low (1Mbps)
|
|
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
|
|
.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 e Ar 0|1
|
|
Enable or disable WEP encryption.
|
|
Permitted values are
|
|
.Ar 0
|
|
(encryption disabled) or
|
|
.Ar 1
|
|
(encryption enabled). Encryption is off by default.
|
|
.It Fl i Ar iface Fl k Ar key "[-v 1|2|3|4]"
|
|
Set WEP encryption keys.
|
|
There are four default encryption keys
|
|
that can be programmed.
|
|
A specific key can be set using
|
|
the
|
|
.Fl v
|
|
flag.
|
|
If the
|
|
.Fl v
|
|
flag is not specified, the first key will be set.
|
|
Encryption keys
|
|
can either be normal text (i.e. "hello") or a series of hexadecimal
|
|
digits (i.e. "0x1234512345"). For
|
|
WaveLAN Turbo Silver cards, the key is restricted to 40 bits, hence
|
|
the key can be either a 5 character text string or 10 hex digits.
|
|
For WaveLAN Turbo Gold cards, the key can also be 104 bits,
|
|
which means the key can be specified as either a 13 character text
|
|
string or 26 hex digits in addition to the formats supported by the
|
|
Silver cards.
|
|
.It Fl i Ar iface Fl T Ar 1|2|3|4
|
|
Specify which of the four WEP encryption keys will be used to
|
|
encrypt transmitted packets.
|
|
.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 default channel is 14,
|
|
and it is the only available channel for pre-11Mbps NICs.
|
|
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
|
|
.Ar 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).
