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. .Bl -column "Channel ID " "FCC " "ETSI " "France " "Japan " -offset indent .Em "Channel ID FCC ETSI France Japan" 1 2412 2412 - 2412 2 2417 2417 - 2417 3 2422 2422 - 2422 4 2427 2427 - 2427 5 2432 2432 - 2432 6 2437 2437 - 2437 7 2442 2442 - 2442 8 2447 2447 - 2447 9 2452 2452 - 2452 10 2457 2457 2457 2457 11 2462 2462 2462 2462 12 - 2467 2467 2467 13 - 2472 2472 2472 14 - - - 2484 .El .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 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). .El .Sh SEE ALSO .Xr wi 4 , .Xr ifconfig 8 .Sh HISTORY The .Nm command first appeared in .Fx 3.0 . .Sh AUTHORS The .Nm command was written by .An Bill Paul Aq wpaul@ctr.columbia.edu .
