NAME

       iwlist - Get more detailed wireless information from a wireless interface

SYNOPSIS

       iwlist [interface] scanning
       iwlist [interface] frequency
       iwlist [interface] rate
       iwlist [interface] keys
       iwlist [interface] power
       iwlist [interface] txpower
       iwlist [interface] retry
       iwlist [interface] event
       iwlist [interface] auth
       iwlist [interface] wpakeys
       iwlist [interface] genie
       iwlist [interface] modulation
       iwlist --help
       iwlist --version

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 spe-
	      cific 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/regis-
	      tered 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.
