DESCRIPTION

       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).

PARAMETERS

       scan[ning]
              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.

       freq[uency]/channel
              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.

       rate/bit[rate]
              List the bit-rates supported by the device.

       keys/enc[ryption]
              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 device.

       txpower
              List the various Transmit Powers available on the device.

       retry  List the transmit retry limits and retry lifetime on the device.

       ap/accesspoint/peers
              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 This feature is obsolete and now deprecated  in  favor  of  scanning  support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 parameters currently set.

       wpa[keys]
              List all the WPA encryption keys set in the device.

       genie  List the Generic Information Elements set in the device (used for WPA support).

       modu[lation]
              List the modulations supported by the device and the modulations currently enabled.

       --version
              Display  the  version of the tools, as well as the recommended and current Wireless
              Extensions version for the tool and the various wireless interfaces.

       --help Display short help message.
