iwlist - Get more detailed wireless information from a wireless interface

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).

       iwlist - Get more detailed wireless information from a wireless interface

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              is  obsolete  and  now  deprecated  in  favor  of scanning support (above), and most drivers don't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