In this article, we’ll delve into the world of WPS, exploring its benefits, risks, and the consequences of pressing that button on your WiFi router.
What is WPS and How Does it Work?
WPS stands for WiFi Protected Setup, a standard developed by the WiFi Alliance to make it easy for users to connect devices to their wireless network without having to enter the network’s password. The idea behind WPS is to simplify the process of adding new devices to your network, making it more accessible to those who are not tech-savvy.
When you press the WPS button on your router, it activates a discovery mode that allows devices to connect to your network without entering the password. Here’s how it works:
- The router broadcasts its SSID (network name) and a unique identifier, known as the PIN.
- The device you want to connect (e.g., a laptop, smartphone, or smart TV) detects the router’s signal and sends a request to connect.
- The router and device exchange information, including the PIN, to authenticate the connection.
- Once authenticated, the device is connected to your network, and you can start using it to access the internet.
WPS Connection Methods
There are two primary methods to connect devices using WPS:
- PIN Method: This method requires you to enter the PIN displayed on the router into the device you want to connect. This method is more secure, as it requires the device to have the correct PIN to connect.
- PBC (Push Button Configuration) Method: This method is the one we’re focusing on in this article. When you press the WPS button on your router, it activates the PBC method, allowing devices to connect without entering the PIN.
Benefits of Using WPS
