What is a WPS number?
The Wi-Fi Protected Setup (WPS) is a security protocol for creating secure wireless home networks. It is designed to allow users who are not technically savvy to access a wireless network in a secure and easy manner .Additionally, new devices can be added easily by entering the WPS PIN code. This code can be found on the wireless router itself. WPS has a security hole that was uncovered in December 2011, so it should not be used anymore.
