The wiconfig
command controls the
operation of WaveLAN/IEEE wireless networking devices via the
wi(4) and
awi(4) 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.
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.).
With no extra options, wiconfig
will
display the current settings of the specified WaveLAN/IEEE interface.
The options are as follows:
-A
1|2-a
access_point_density-D
-d
max_data_length-h
-M
0|1In 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), or a microwave oven is operating near the antenna of the WLAN peer or access point, 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 does not impact the visible MTU of the link.

command first appeared in
FreeBSD 3.0, as wicontrol

It was added to NetBSD 1.5 under its present
name.
