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
       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, Qual-
              ity, 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) will be
              impacted by the current setting of the driver. Also,  this  com-
              mand is supposed to take extra arguments to control the scanning
              behaviour, but this is currently not implemented.

       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.

       key/enc[ryption]
              List the encryption key sizes  supported  and  display  all  the
              encryption keys available 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 This feature is obsolete and now depre-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.

       --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.
