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 take optional arguments, however most drivers  will
              ignore  those.  The  option essid is used to specify a scan on a
              specific ESSID. The option last do 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  This  feature  is obsolete and now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 parametes curently 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.
