DESCRIPTION
       Iwlist is used to display some additional information from  a  wireless
       network interface that is not displayed by iwconfig(8).  The main argu-
       ment is used to select a category of information,  iwlist  displays  in
       detailed  form  all information related to this category, including in-
       formation 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, Qual-
              ity, Frequency, Mode...). The type of information  returned  de-
              pends 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  hid-
              den  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 map-
              ping 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 encryp-
              tion 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 This feature is obsolete and now depre-
              cated 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  associ-
              ated/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.
