push-button - WPS is activated by pushing physical button on the board (few boards has such button marked on the board case/label)
简单的说就是你要开启WPS按钮功能
WPS Server is active only when wireless AP interface has Pre-Shared Key Authentication (PSK) enabled. It is possible to configure this mode for the Virtual AP interfaces as well.
无线认证必须开启PSK认证。
