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 a list of parameters.

Parameters

freq/channel

Gives 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

Gives 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 This feature is obsolete and now deprecated in favor of scanning support (below), and it will disappear in the future.

scan[ning]

Gives the list of Access Points and ad-hoc cells in range, and optionally a great deal of information about them (ESSID, quality, frequency, mode, etc.). 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 leftover 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 behavior, but this is currently not implemented.

rate/bit[rate]

Lists the bit-rates supported by the device.

key/enc[ryption]

Lists the encryption key sizes supported and displays all the encryption keys available in the device.

power

Lists the various Power Management attributes and modes of the device.

txpower

Lists the various Transmit Power available on the device.

retry

Lists the transmit retry limits and retry lifetime on the device.

- -version

Displays the version of the tools, as well as the recommended and current Wireless Extensions version for the tool and the various wireless interfaces.
