DESCRIPTION

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).

PARAMETERS

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
47       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
54       rate/bit[rate]
55              List the bit-rates supported by the device.
56
57       keys/enc[ryption]
58              List the encryption key sizes supported and list all the encryp‐
59              tion keys set in the device.
60
61       power  List the various Power Management attributes and  modes  of  the
62              device.
63
64       txpower
65              List the various Transmit Powers available on the device.
66
67       retry  List the transmit retry limits and retry lifetime on the device.
68
69       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 This feature is obsolete and now depre‐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
79       event  List the wireless events supported by the device.
80
81       auth   List the WPA authentication parametes curently set.
82
83       wpa[keys]
84              List all the WPA encryption keys set in the device.
85
86       genie  List  the  Generic  Information Elements set in the device (used
87              for WPA support).
88
89       modu[lation]
90              List the modulations supported by the device and the modulations
91              currently enabled.
92
93       --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
98       --help Display short help message.
