iwconfig - Linux command to configure a wireless network interface

Iwconfig  is  similar  to ifconfig(8), but is dedicated to the wireless interfaces. It is used to set the parameters of the  network  interface which  are  specific  to the wireless operation (for example : the fre‐quency).  Iwconfig may also be used to display  those  parameters,  and the wireless statistics (extracted from /proc/net/wireless).

All  these  parameters and statistics are device dependent. Each driver will provide only some of them depending on hardware support,  and  the range of values may change. Please refer to the man page of each device for details.
