Configure WaveLAN/IEEE devices
wiconfig interface [-Dho] [-A 1|2] [-a access_point_density] [-d max_data_length] [-g fragmentation_threshold] [-M 0|1] [-m MAC_address] [-R 1|3] [-r RTS_threshold] [-s station_name]
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.
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.
|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.).
