As the world becomes increasingly dependent on wireless connectivity, the security of our Wi-Fi networks has become a pressing concern. One often-overlooked feature that can compromise the security of your network is Wi-Fi Protected Setup (WPS). In this article, we’ll delve into the world of WPS, exploring what it is, how it works, and most importantly, why you should consider turning it off.
What is Wi-Fi Protected Setup (WPS)?
Wi-Fi Protected Setup (WPS) is a feature designed to make it easy to connect devices to a secure Wi-Fi network. Introduced in 2006 by the Wi-Fi Alliance, WPS aims to simplify the process of setting up a secure connection between a router and a device. The feature uses a PIN or a push-button to establish a connection, eliminating the need to manually enter a password.
How Does WPS Work?
WPS operates in two main modes:
- PIN Mode: In this mode, the router generates a unique PIN, which is then entered into the device to establish a connection.
- Push-Button Mode: This mode involves pressing a physical button on the router and the device, which then automatically establishes a secure connection.
While WPS may seem like a convenient feature, it has several security vulnerabilities that make it a potential threat to your network’s security.
The Security Risks of WPS
Despite its intended purpose of simplifying the connection process, WPS has several security risks that can compromise your network’s security.
Brute-Force Attacks
One of the most significant security risks associated with WPS is the vulnerability to brute-force attacks. In PIN mode, the PIN is only 8 digits long, which makes it relatively easy for hackers to guess the correct PIN using automated tools. This can lead to unauthorized access to your network.
Reaver Exploit
In 2011, a security researcher discovered a vulnerability in WPS, known as the Reaver exploit. This exploit allows hackers to recover the WPS PIN and gain access to the network. The Reaver exploit is particularly concerning, as it can be used to attack networks that use WPS, even if the network is secured with a strong password.
Denial of Service (DoS) Attacks
WPS can also be used to launch Denial of Service (DoS) attacks against a network. By continuously sending WPS requests to the router, hackers can overwhelm the device and cause it to become unresponsive.
Why You Should Turn Off WPS
Given the security risks associated with WPS, it’s highly recommended that you turn off this feature to protect your network.
Preventing Unauthorized Access
By disabling WPS, you can prevent unauthorized access to your network. Without WPS, hackers will not be able to use brute-force attacks or exploits like Reaver to gain access to your network.
Reducing the Risk of DoS Attacks
Turning off WPS can also reduce the risk of DoS attacks against your network. By disabling WPS, you can prevent hackers from overwhelming your router with WPS requests.
Improving Network Security
Disabling WPS is just one step in improving your network’s security. By combining this with other security measures, such as using strong passwords and keeping your router’s firmware up to date, you can significantly improve the security of your network.
How to Turn Off WPS
Turning off WPS is a relatively straightforward process that can be completed in a few steps.
Checking if WPS is Enabled
Before you can turn off WPS, you need to check if it’s enabled on your router. To do this:
- Log in to your router’s web interface using a web browser.

- Save your changes.
Alternatives to WPS
If you’re concerned about the security risks associated with WPS, there are alternative methods for connecting devices to your network.
Manual Connection
One alternative to WPS is to manually connect devices to your network using the network’s password. This method is more secure than WPS, as it requires the device to enter the correct password to establish a connection.
Wi-Fi Easy Connect
Wi-Fi Easy Connect is a feature that allows devices to connect to a network using a QR code or a NFC tag. This feature is more secure than WPS, as it uses a secure authentication process to establish a connection.
Conclusion
In conclusion, WPS is a feature that can compromise the security of your network. By understanding the security risks associated with WPS and taking steps to disable it, you can significantly improve the security of your network. Remember to always prioritize network security and take steps to protect your network from potential threats.
By turning off WPS and using alternative methods for connecting devices to your network, you can ensure that your network remains secure and protected from unauthorized access.
What is WPS and how does it work?
WPS, or Wi-Fi Protected Setup, is a feature that allows users to easily connect devices to their Wi-Fi network without having to manually enter the network’s password. It was designed to simplify the process of connecting devices to a network, especially for those who are not tech-savvy. When a device is connected to a network using WPS, it uses an eight-digit PIN or a push-button method to authenticate the connection.
While WPS may seem convenient, it has several security vulnerabilities that make it a potential threat to your network’s security. For example, the eight-digit PIN can be easily guessed or cracked using brute-force attacks, allowing unauthorized devices to connect to your network. Additionally, the push-button method can be exploited by hackers who are within physical range of your router.
What are the security risks associated with WPS?
The main security risk associated with WPS is that it can be exploited by hackers to gain unauthorized access to your network. As mentioned earlier, the eight-digit PIN can be easily guessed or cracked, and the push-button method can be exploited by hackers who are within physical range of your router. Once a hacker gains access to your network, they can steal sensitive information, install malware, or use your network to launch attacks on other networks.
Another security risk associated with WPS is that it can be used to launch a denial-of-service (DoS) attack on your network. A DoS attack can cause your network to become slow or unresponsive, making it difficult for legitimate devices to connect. This can be especially problematic for businesses or organizations that rely on their network to operate.
How can I protect my network from WPS-related threats?
To protect your network from WPS-related threats, the simplest solution is to turn off WPS altogether. This will prevent hackers from exploiting the feature to gain unauthorized access to your network. You can usually find the option to turn off WPS in your router’s settings, often under the “Wireless Settings” or “Advanced Settings” section.
