.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:
.Bd -filled -offset indent
.Bl -column "TX rate " "NIC speed "
.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
.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 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 be up to 128 bits,
which means the key can be specified as either a 16 character text
string or 32 hex digits.
.Pp
Note: currently, the field in the structure used to program the key
into the NIC is only 14 bytes long, not 16.
I'm not sure how this is
supposed to allow 128 bits of key info for the gold 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.

.Pp
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).
