Give the list of Access Points and Ad-Hoc cells in range, and
optionally a whole bunch of information about them (ESSID, Quality,
Frequency, Mode…). The type of information returned depends on
what the card supports.
Triggering scanning is a privileged operation (root only) and normal
users can only read left-over scan results. By default, the way
scanning is done (the scope of the scan) is dependant on the card
and card settings.
This command takes optional arguments, however most drivers will
ignore those. The option essid is used to specify a scan on a spe‐
cific ESSID. With some card/driver, this enables to see hidden net‐
works. The option last does not trigger a scan and read left-over
Give the list of available frequencies in the device and the number
of defined channels. Please note that usually the driver returns the
total number of channels and only the frequencies available in the
present locale, so there is no one-to-one mapping between frequen‐
cies displayed and channel numbers.
List the bit-rates supported by the device.
List the encryption key sizes supported and list all the encryption
keys set in the device.
List the various Power Management attributes and modes of the device.
List the various Transmit Powers available on the device.
List the transmit retry limits and retry lifetime on the device.
Give the list of Access Points in range, and optionally the quality
of link to them. This feature is obsolete and now deprecated in
favor of scanning support (above), and most drivers don’t support
Some drivers may use this command to return a specific list of Peers
or Access Points, such as the list of Peers associated/registered
with the card. See your driver documentation for details.
List the wireless events supported by the device.
List the WPA authentication parameters currently set.
List all the WPA encryption keys set in the device.
List the Generic Information Elements set in the device (used for WPA support).
List the modulations supported by the device and the modulations
