Wi-Fi Protected Setup (WPS) is a standard that allows users to set up a wireless network in an easy and secure way. To set up a wireless network using traditional methods, you must enter the wireless access point's service set identifier (SSID), and to prevent unauthorized access to the wireless local area network (WLAN), its security key. If the WPS standard is used, you do not need to know the SSID or the security key because the access point and the client will automatically set them.
