iwconfig 命令

常用示例

说明

iwconfig is similar to ifconfig, but is dedicated to wireless network interfaces. It is used to set parameters specific to wireless operation such as ESSID, frequency, mode, encryption key, and power management. It can also display those parameters along with wireless statistics from /proc/net/wireless. When called without arguments, iwconfig displays the wireless parameters for all interfaces. When called with an interface name only, it displays the settings for that interface.
