Wifi protected setup (WPS)

Last Updated on January 23, 2024 by Abhishek Sharma

Wi-Fi Protected Setup (WPS) is a convenient method designed to simplify the process of connecting devices to a secure wireless network. Introduced as a means to make setting up a Wi-Fi connection easier for users, WPS was intended to streamline the often complex process of entering long passphrases or network keys. However, as technology advances and security concerns evolve, there have been discussions around potential vulnerabilities associated with WPS. This article aims to delve into the intricacies of WPS, exploring its functionality, security implications, and addressing common questions to better understand its role in modern wireless networking.

What is WPS?

Wi-Fi Protected Setup (WPS) is a standardized protocol that simplifies the process of connecting devices to a secure wireless network. It was developed to ease the often complex task of manually entering a Wi-Fi network passphrase or security key by providing a more user-friendly and streamlined method of authentication and connection.

WPS offers multiple ways for devices to join a Wi-Fi network without requiring users to input lengthy passwords. It typically includes two primary methods: Push Button Configuration (PBC) and PIN Entry.

Push Button Configuration (PBC): In this method, a physical button on the router and the connecting device are pressed within a specific timeframe, initiating the connection without the need for entering a password.

PIN Entry: The PIN Entry method involves entering an eight-digit PIN displayed on the router’s label into the device seeking to connect. This process can also facilitate the connection without directly entering the Wi-Fi network passphrase.

What can WPS do?

Wifi Protected Setup (WPS) is designed to simplify the process of connecting wireless devices to a secured Wi-Fi network. Here are some key features and functionalities of WPS:

1. Quick and Easy Setup: WPS aims to provide a quick and easy method for users to connect their devices to a Wi-Fi network without manually entering a long and complex password. This is particularly useful for users who may find it cumbersome to type in a password on devices with limited input capabilities.
2. Push Button Configuration: One of the common methods used by WPS is the push-button configuration. The router typically has a physical button, and users can initiate the WPS process by pressing this button on the router and then activating WPS on the device they want to connect. The connection is established without the need to enter a password manually.
3. PIN-based Authentication: WPS also supports PIN-based authentication. Each WPS-enabled device and router has a unique eight-digit PIN. Users can enter this PIN on their device to establish a connection. This method provides an alternative to the push-button configuration.
4. Compatibility with WPA/WPA2: WPS is designed to work with Wi-Fi networks that are secured using the Wifi Protected Access Personal (WPA) or Wifi Protected Access2 (WPA2) security protocols. These protocols are considered more secure than the older Wired Equivalent Privacy (WEP) protocol.
5. Automatic Configuration: Once the WPS process is initiated, the devices involved exchange necessary information automatically, allowing for the configuration of the wireless connection without requiring user intervention.
6. Temporary Connections: WPS often creates a temporary connection between the device and the router during the setup process. Once the connection is established, the device is added to the list of authorized devices, and the temporary connection is no longer used.

Advantages of WPS

Here are the advantages of WPS.

1. Simplified Setup Process: WPS significantly simplifies the process of connecting devices to a secured Wi-Fi network, making it more user-friendly, especially for those who may struggle with entering complex passwords.
2. Quick and Convenient: With WPS, users can establish a connection quickly and conveniently, eliminating the need to manually enter lengthy passwords. This is particularly useful for devices with limited input capabilities, such as smart TVs or Internet of Things (IoT) devices.
3. User-Friendly: The push-button configuration and PIN-based authentication make WPS easy to use, even for individuals with limited technical expertise.
4. Compatibility: WPS is designed to work with WPA and WPA2 security protocols, which are considered more secure than the outdated WEP protocol.
5. Automatic Configuration: The automatic exchange of necessary information during the WPS process streamlines the configuration of the wireless connection, reducing the likelihood of user errors.

Disadvantages of WPS

Here are some disadvantages of wps.

1. Security Concerns: One of the primary drawbacks of WPS is its potential security vulnerabilities. The PIN-based method, in particular, has been criticized for being susceptible to brute-force attacks, potentially compromising the security of the Wi-Fi network.
