-A 1|2
Set the authentication type for a specified interface. Permitted values are 1 (Open System Authentication) or 2 (Shared Key Authentication). The default is 1.
-a access_point_density
Specify the 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.
This forces the driver to initiate one round of access point scanning. All of the access points found are displayed.
-d max_data_length
Set the maximum receive and transmit frame size for a specified interface. The maximum data length can be any number from 256 to 2346. The default is 2304.
-g fragmentation_threshold
Set the fragmentation threshold.
Display a short help message.
-M 0|1
Enable or disable "microwave oven robustness" on a given interface. This should only be used if needed.

In cases of slow performance where there is a good quality signal but also high levels of noise (i.e., the signal-to-noise ratio is bad, but the signal strength is good), and there is an operating microwave oven in or near the signal path, this option may be of use.

In bad signal-to-noise conditions, the link layer will switch to lower transmit rates. However at lower transmit rates, individual frames take longer to transmit, making them more vulnerable to bursty noise. The option works by enabling data fragmentation in the link layer as the transmit speed lowers in an attempt to shorten the transmit time of each frame so that individual frames are more likely to be transmitted without error.

Note that this doesn't impact the visible MTU of the link.

-m MAC_address
Set the station address for the specified interface. The 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.
Print out the statistics counters instead of the card settings. Note that, however, the statistics are updated only every minute or so.
-R 1|3
Enable or disable roaming function on a given interface. The legal values are 1 (roaming handled by firmware) and 3 (roaming disabled). The default is 1.
-r 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 RTS_threshold can be any value between 0 and 2347. The default is 2347, which indicates that the RTS/CTS mechanism is never to be used.
-s station_name
Sets the station name, which is used for diagnostic purposes, for the specified interface. The Lucent WaveMANAGER software can poll the names of remote hosts.


The wiconfig command controls the operation of WaveLAN/IEEE wireless networking devices via the wi and awi drivers. The wiconfig 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.

Note: You aren't likely to need this utility; ifconfig can handle the device configuration required without needing this utility.

With no extra options, wiconfig displays the current settings of the specified WaveLAN/IEEE interface.

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 interface argument given to wiconfig should be the logical interface name associated with the WaveLAN/IEEE device (e.g., wi0, wi1, etc.).
