information from a wireless network interface not displayed by iwconfig

scan[ning] Access Points and Ad-Hoc cells in range, and optionally (ESSID, Quality, Frequency, Mode...).
information returned depends on the card .
privileged operation (root ), normal users read left-over scan results.
By default, the scope of the scan is dependant on the card and card settings.
optional arguments, however most drivers will ignore those.
essid is used to specify a scan on a specific ESSID.
May enable hidden networks. last does not trigger a scan and read left-over scan results.
freq[uency]/channel of available frequencies in the device and the number of defined channels.
driver returns the total number of channels and only the frequencies available in the present locale, there is no one-to-one mapping between frequencies displayed and channel numbers.
retry transmit retry limits and retry lifetime
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 This feature is obsolete and now dep- recated in favor of scanning support (above), and most drivers don't support it.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 associ- ated/registered with the card. See your driver documentation for details.
event List the wireless events supported by the device.
auth List the WPA authentication parameters currently 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 as well as the recommended and current Wireless Extensions version for the tool and the various wireless interfaces.
