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 typically 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.
