What is a WPS number?
Wi-Fi Protected Setup (WPS) is a network security standard for to enable and create secure wireless home networks. The goal of the protocol is to allow users that are technically not able to setup a secure and easy setup/connection themselves on their wireless network. New devices can be easily added as well, simply by adding the WPS PIN code. This code can be found on the wireless router itself. WPS has a major security flaw which was revealed in december 2011, and should therefore not be used anymore.
