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
in detailed form all information related to this category, including
information already shown by iwconfig
- 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
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
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
- 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.
- List the bit-rates supported by the device.
- List the encryption key sizes supported and list all the
encryption keys set in the device.
- List the various Power Management attributes and modes of
- List the various Transmit Powers available on the
- List the transmit retry limits and retry lifetime on the
- 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 This feature is obsolete and now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
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.
- List the wireless events supported by the device.
- List the WPA authentication parameters currently set.
- List all the WPA encryption keys set in the device.
- List the Generic Information Elements set in the device
(used for WPA support).
- List the modulations supported by the device and the
modulations currently enabled.
- Display the version of the tools, as well as the
recommended and current Wireless Extensions version for the tool and the
various wireless interfaces.
- Display short help message.
