24 but is dedicated to the wireless interfaces. It is used to set the
25 parameters of the network interface which are specific to the wireless
26 operation (for example : the frequency).
28 may also be used to display those parameters, and the wireless
29 statistics (extracted from
30 .IR /proc/net/wireless ).
32 All these parameters and statistics are device dependant. Each driver
33 will provide only some of them depending on the hardware support, and
34 the range of value may change. Please refer to the man page of each
42 Set the Network ID (in some products it is also called Domain). As all
43 adjacent wireless networks share the same medium, this number is used
44 to differenciate them (create virtual networks).
47 Set the operating frequency or channel in the device. Value below 1000
48 are the channel number, value over this is the frequency in Hz. You
49 may prepend the suffix k, M or G to the value (for example, "2.46G"
50 for 2.46 GHz frequency).
55 For each device which support wireless extensions,
57 will display the name of the
59 used (name of device for proprietary protocols), the
69 will also display its content :
72 Quality of the link or the modulation (how good the received signal is).
75 Received signal strength (how strong the received signal is).
78 Background noise level (when no packet is transmited).
81 Number of packets received with a different NWID. Used to detect
82 configuration problems or adjacent network existence.
85 Number of packets that the hardware was unable to decrypt.
88 Other packets lost in relation with specific wireless operations.
