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              is obsolete and now deprecated in favor of  scanning  support  (above),  and  most  drivers  don't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.
