What is WPS and How Does it Work?

You must have come across the term WPS while setting up a Wi-Fi router. It is a small button next to the ethernet cable port on the back of the router. Although it is present in almost all wireless routers, only a few people know its purpose.

What is WPS and How Does it Work

What is WPS?

WPS stands for Wi-Fi Protected System, and Wi-Fi Alliance first created it to make the entire process of setting up a wireless network simple and easy. It made to make lives easier for those people who aren’t that tech-savvy. In the times before WPS, you needed to possess a good deal of knowledge about Wi-Fi and configuration models in order to set up a wireless network.

WPS technology works with wireless networks that use WPA Personal or WPA2 security protocols to encrypt and a password to secure the network. WPS, however, does not work if the security protocol being used is WEP, as it is not very safe and can easily be hacked into.

Every network has a specific name, which is known as SSID. To connect to a network, you need to know both its SSID and its password. Take, for example, the simple process of connecting your mobile phone to a Wi-Fi network. The first thing that you do is switch on the Wi-Fi on your mobile and search for available networks. When you find the one that you wish to connect to, you tap on it and then enter the password. If the password is correct, then you will be connected to the device. However, with the use of WPS, you can make this process even simpler. This will be discussed in the next section.

Some routers even have WPS enabled by default. Every Wi-Fi router comes with either the WPS button or at least support for WPS. Those routers that do not have a physical push button need WPS to be configured using the router’s firmware.

Where is the WPS button situated

As mentioned earlier, most of the wireless routers have a WPS button located at the back of the device adjacent to the ethernet port. The exact position and design differ from one brand to the other. For some devices, a single button acts as the power button and WPS button. A simple short press is used to turn on or off the Wi-Fi, and a long press is used to enable/disable WPS.

One of the main drawbacks of WPS is that it is not very safe. As mentioned earlier, WPS uses an 8-digit PIN to establish a secure connection. Although this PIN is auto-generated and not used by people, there is a strong chance that this PIN can be cracked by hackers using brute force.

The 8-digit PIN is stored in two blocks of 4 digits each. This makes it easier to tackle each block individually, and instead of creating 8-digit combinations, two 4-digit combinations are more comfortable to crack. Using his standard brute force tools, a hacker can crack this code in 4-10 hours or a maximum of a day. After that, they can access the security key and gain complete access to your wireless network.
