Iwlist is used to display some additional information from a wireless
network interface that is not displayed by iwconfig(8). The main
argument is used to select a category of information, iwlist displays
in detailed form all information related to this category, including
information already shown by iwconfig(8).
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
specific ESSID. With some card/driver, this enables to see
hidden networks. The option last does not trigger a scan and
read left-over scan results.
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 frequencies 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.
power List the various Power Management attributes and modes of the
List the various Transmit Powers available on the device.
retry 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 This feature is obsolete and now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 it.
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.
event List the wireless events supported by the device.
auth List the WPA authentication parametes curently set.
List all the WPA encryption keys set in the device.
genie List the Generic Information Elements set in the device (used
for WPA support).
List the modulations supported by the device and the modulations

current Wireless Extensions version for the tool and the various
