Introduction to WPS
WPS was introduced by the Wi-Fi Alliance in 2006 with the aim of simplifying the process of connecting devices to wireless networks. The primary goal was to make it easy for non-technical users to set up and secure their wireless networks. Before WPS, setting up a wireless network involved manually entering the network’s SSID (network name) and WEP/WPA key (password) on each device. This process could be cumbersome, especially for those not familiar with networking terminology.
How WPS Works
WPS operates on the principle of simplifying the connection process by eliminating the need to manually enter network credentials. There are two main methods through which WPS facilitates connections: the Push Button Configuration (PBC) method and the Personal Identification Number (PIN) method.
- Push Button Configuration (PBC) Method: This is the most common method of using WPS. It involves pressing a button (either physical or virtual) on the router and then on the device you want to connect. Once both buttons are pressed within a short time frame (usually 2 minutes), the router and device automatically exchange the necessary information to establish a secure connection.
- Personal Identification Number (PIN) Method: In this method, a PIN is generated by the router or the device. The user then enters this PIN into the other device to authenticate and establish the connection.
Benefits of Using WPS
The convenience and ease of use offered by WPS are its most significant advantages. Here are some key benefits that contribute to its popularity:
WPS makes it incredibly easy for anyone to set up a secure wireless network.
