26 Iwlist is used to display some additional information from a wireless
27 network interface that is not displayed by iwconfig(8). The main argu‐
28 ment is used to select a category of information, iwlist displays in
29 detailed form all information related to this category, including
30 information already shown by iwconfig(8).
31
33 scan[ning]
34 Give the list of Access Points and Ad-Hoc cells in range, and
35 optionally a whole bunch of information about them (ESSID, Qual‐
36 ity, Frequency, Mode...). The type of information returned
37 depends on what the card supports.
38 Triggering scanning is a privileged operation (root only) and
39 normal users can only read left-over scan results. By default,
40 the way scanning is done (the scope of the scan) is dependant on
41 the card and card settings.
42 This command take optional arguments, however most drivers will
43 ignore those. The option essid is used to specify a scan on a
44 specific ESSID. The option last do not trigger a scan and read
45 left-over scan results.
46 freq[uency]/channel
48 Give the list of available frequencies in the device and the
49 number of defined channels. Please note that usually the driver
50 returns the total number of channels and only the frequencies
51 available in the present locale, so there is no one-to-one map‐
52 ping between frequencies displayed and channel numbers.
53 rate/bit[rate]
55 List the bit-rates supported by the device.
56 keys/enc[ryption]
58 List the encryption key sizes supported and list all the encryp‐
59 tion keys set in the device.
60 power List the various Power Management attributes and modes of the
62 device.
63 txpower
65 List the various Transmit Powers available on the device.
66 retry List the transmit retry limits and retry lifetime on the device.
68 ap/accesspoint/peers
70 Give the list of Access Points in range, and optionally the
71 quality of link to them. This feature is obsolete and now depre‐
72 cated in favor of scanning support (above), and most drivers
73 don't support it.
74 Some drivers may use this command to return a specific list of
75 Peers or Access Points, such as the list of Peers associ‐
76 ated/registered with the card. See your driver documentation for
77 details.
78 event List the wireless events supported by the device.
80 auth List the WPA authentication parametes curently set.
82 wpa[keys]
84 List all the WPA encryption keys set in the device.
85 genie List the Generic Information Elements set in the device (used
87 for WPA support).
88 modu[lation]
90 List the modulations supported by the device and the modulations
91 currently enabled.
92 --version
94 Display the version of the tools, as well as the recommended and
95 current Wireless Extensions version for the tool and the various
96 wireless interfaces.
97 --help Display short help message.
