IWLIST(8)						     Linux Programmer's Manual							 IWLIST(8)

NAME

       iwlist - Get wireless statistics from specific nodes

SYNOPSIS

       iwlist interface freq
       iwlist interface ap
       iwlist interface scan
       iwlist interface rate
       iwlist interface key
       iwlist interface power
       iwlist interface txpower
       iwlist interface retry
       iwlist --help
       iwlist --version

DESCRIPTION

       Iwlist is used to display some large chunk of information from a wireless network interface that is not displayed by iwconfig. This is typ-
       ically list of parameters.

PARAMETERS

       freq/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.

       ap/accesspoint
	      Give the list of Access Points in range, and optionally the quality of link to them. This feature is obsolte and now  deprecated	in
	      favor of scanning support (below), and it will disappear in the future.

       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 depend on what the card support.
	      Triggering scanning is a priviledged operation (root only) and normal users can only read letf-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 command is supposed
	      to take extra arguments to control the scanning behaviour, but this is currently not implemented.

       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 availables in the device.

       power  List the various Power Management attributes and modes of the device.

       txpower
	      List the various Transmit Power available on the device.

       retry  List the transmit retry limits and retry lifetime on 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.

FILES

       /proc/net/wireless
