Modern wireless network security standards require complex passwords consisting of dozens of symbols, numbers, and special characters. Entering such a combination every time you need to connect a guest or a new device to your network can be inconvenient and time-consuming. It was precisely to simplify this process that the technology was developed. WPS, which allows you to log in to the network without manually entering a password.
One of the most reliable methods of implementing this technology is the use of a unique PIN codeThis eight-digit digital key is usually found on a sticker on the bottom of the router or can be generated software-generated. Unlike the Push-Button method, using a PIN code allows you to connect devices that do not have physical access to the router.This is especially true if the router is mounted high on the wall or located in another room.
In this article, we'll detail how to find this code, where to enter it on various devices, and what security measures to take. Understanding how it works Wi-Fi Protected Setup This will not only speed up the connection process but also secure your home network from unauthorized access. We'll cover the specifics for Windows operating systems and mobile platforms.
What is a WPS PIN and where can I find it?
WPS stands for Wi-Fi Protected Setup. It's a standard developed by the Wi-Fi Alliance to simplify the creation of a home wireless network. The technology automatically transmits security settings (SSID and encryption key) from the router to the client device. There are two main activation methods: a physical button on the router's body and entering a digital code.
PIN code is an 8-digit number that serves as an authorization key. It's important to understand that this code is not a Wi-Fi password in the traditional sense. It's a temporary or permanent identifier that allows the device to request the necessary connection data from the router. On most modern router models, TP-Link, Asus, Zyxel And Keenetic This code is static and is prescribed by the manufacturer.
There are several ways to find this code. The easiest is to turn the router over and look at the information sticker. There's usually a combination of numbers printed next to the words "PIN Code" or "WPS PIN." If the sticker is worn off or the router is in an inaccessible location, the code can be found in the device's web interface. To do this, access the router's settings through a browser by entering the gateway IP address (often 192.168.0.1 or 192.168.1.1) in the address bar.
After logging into the control panel (the login and password are often also indicated on the sticker), go to the wireless network section. Depending on the firmware, the required setting may be in the "WPS," "Wireless," or "Wi-Fi" subsections. The current PIN code will be displayed there. On some models, for example, MikroTik or Ubiquiti, this functionality may be hidden or require enabling in additional security settings.
⚠️ Warning: Some older router models had a vulnerability that allowed brute-force attacks on PIN codes. If your router was released more than 10 years ago, we strongly recommend updating your firmware to the latest version or disabling the WPS function in the settings if you don't use it.
The table below shows examples of WPS settings locations for popular router brands:
| Router brand | Path to the settings menu | Location on the body |
|---|---|---|
| TP-Link | Wireless -> WPS | On the sticker at the bottom, sometimes there is a "WPS" button |
| Asus | Administration -> System or Wireless -> WPS | A separate button on the back or combined with Reset |
| Zyxel Keenetic | Wi-Fi network -> WPS | Button with a lock icon or Wi-Fi |
| D-Link | Wi-Fi -> WPS | On the front or back of the case, there is a "WPS" button |
Connecting to Wi-Fi via WPS PIN on Windows
Windows operating systems, from version 7 to the current Windows 11, have built-in support for WPS technology. This allows you to connect to hidden or secure networks without directly entering long passwords. The process is initiated by the computer, which acts as the requesting device.
First, open the list of available wireless networks. In Windows 10 and 11, this is done by clicking the Wi-Fi icon in the system tray (lower-right corner of the screen). Select the desired network from the list. If the network is hidden, select "Hidden network" and enter its name (SSID). In the password entry window, instead of typing characters, look for the "Enter WPS PIN" button or link.
After clicking this button, the system will offer two options: either press the WPS button on the router or enter a PIN. Select the latter. In the field that appears, enter the 8-digit number found on the router's sticker or in its web interface. After entering, click "Next." The computer will begin searching for the router and sending an authorization request.
The key exchange process can take 10 to 60 seconds. During this time, Windows will attempt to establish a secure connection. If the code is entered correctly and the WPS function is enabled on your router, you will see a message confirming a successful connection. The system will automatically save the network profile, and in future, you will log in automatically when you are in range.
☑️ Pre-connection check on Windows
It's worth noting that the interface may differ on some enterprise Windows builds or when using certain Wi-Fi adapter drivers. In such cases, WPS management can be accomplished through the adapter manufacturer's utilities, such as Intel PROSet or Realtek WLAN UtilityIn these programs, the logic remains the same: search for a network, select the WPS PIN method, and enter the code.
Using WPS PIN on Android and iOS devices
The situation with mobile devices is uneven due to the security policies of different operating systems. Owners of smartphones based on Android have more options for using WPS, although in recent OS versions (Android 9 and above) this function is often hidden or removed from the standard interface.
On devices Samsung, Xiaomi or Huawei With older versions of Android, you can find this feature by going to "Settings" -> "Wi-Fi." By tapping the "More" button or the three-dot menu, you'll find the "WPS by PIN" or "WPS button" option. If you choose to enter a PIN, the phone will generate its own request, but more often, you'll need to enter the router's PIN. If this isn't possible using standard tools, there are third-party apps from Google Play, such as "WPS Connect" or "WiFi WPS Connect," that emulate this process (root access or specific drivers are required).
With devices Apple Things are more complicated for iPhones and iPads. Apple never supported WPS technology in iOS for security reasons and a minimalist ideology. Therefore, connecting to Wi-Fi via WPS PIN on an iPhone using standard means is impossible. The only option is to use a QR code, if the router supports generating one, or manually enter the password.
Why doesn't Apple use WPS?
Apple considers the WPS protocol insecure due to vulnerabilities in the PIN generation method. Instead, Apple promotes the use of iCloud Keychain for automatic password exchange between devices in the ecosystem or QR code connection, which eliminates the risk of brute-force attacks.
For Android devices where the feature is hidden, you can try activating it through the engineering menu or special commands in the terminal, but this requires a high level of skill and may disrupt the Wi-Fi module. It's safer to use alternative connection methods, which are discussed below.
Alternative methods for quick connection
If using a PIN code is impossible for some reason (for example, the sticker is unreadable and the interface is unavailable), there are other quick authorization methods. These are based on the same security principles but use different data transmission channels.
The most modern and convenient method is scanning QR code. Many modern routers (especially models TP-Link And Xiaomi) generate a unique QR code, which is also located on the device's sticker. The smartphone's camera reads this code and automatically fills in all the necessary network parameters, including the password. This works on both Android and iOS (starting with iOS 11).
Another method is to use NFC tags. Some advanced routers are equipped with an NFC module. To connect, simply hold your NFC-enabled smartphone to the top panel of the router. The device will automatically prompt you to connect to the network, and you only need to confirm the action on the screen.
- 📱 QR code: The fastest way for guests, no manual data entry required.
- 📡 NFC: Requires physical proximity of the device, works instantly, but requires an NFC module in the phone.
- 🔘 WPS Button: Physically pressing a button on the router within 2 minutes of a connection request from a device.
Also worth mentioning is the "Password Sharing" feature in the Apple ecosystem and similar features in Google's ecosystem. If one device is already connected to the network, it can share credentials with another nearby device simply upon user request. This doesn't require entering PINs or passwords, but it does require both devices to be in the contact list or have accounts on the same system.
Common mistakes and how to solve them
Despite the simplicity of the technology, users often encounter problems connecting via WPS. The most common error is "Incorrect PIN" or connection timeout. This could mean the code was entered incorrectly, or the function is disabled on the router.
The problem is often that the WPS function is disabled in the router's default settings for security reasons. Many ISPs and manufacturers recommend disabling it if it's not used regularly. To check this, log in to the router's web interface and find the "Enable WPS" switch. Make sure the checkbox is checked or the switch is enabled.
Another reason for failure is an expired timeout. The PIN entry window on the router is open for a limited time (usually 2 minutes). If you don't have time to enter the code on your computer, you need to start the process over again. Some routers also block PIN guessing attempts after several unsuccessful attempts. In this case, rebooting the router (powering it off for 10-15 seconds) helps.
⚠️ Note: Router interfaces are constantly being updated. If you can't find the WPS option in the locations described, check the official manual for your specific model on the manufacturer's website, as the menu location may vary between firmware versions.
If the error persists, try updating the Wi-Fi adapter drivers on your computer. Outdated network card software may not process WPS packets correctly. Visit the laptop or adapter manufacturer's website and download the latest drivers.
Security Questions: Should You Use WPS?
The security of WPS remains a contentious issue. On the one hand, it's convenient. On the other, the WPS protocol, especially its PIN-based implementation, has known vulnerabilities. The PIN generation algorithm in older routers allowed hackers to brute-force the code in a matter of hours using specialized utilities (for example, Reaver).
Modern routers released after 2015-2016 typically have protection against brute-force attacks (blocking after several attempts to enter an incorrect code) and use more complex algorithms. However, if you live in a densely populated area and your network is visible to hundreds of neighbors, the risk remains theoretically possible, although unlikely for the average user.
It's recommended to use the WPS PIN only for initial network setup or for occasional connections with trusted devices. After all devices are successfully connected and configured, it's best to disable the WPS function in the router's web interface. This will close a potential security hole while preserving the functionality of existing devices.
It's also important to keep your router firmware up to date. Manufacturers regularly release patches to address vulnerabilities in the WPS protocol. If your router hasn't received updates for several years, the risk of using WPS is significantly higher.
Frequently Asked Questions (FAQ)
Is it possible to find out the WPS PIN code if the sticker on the router has worn off?
Yes, you can do this through the router's web interface. Go to the settings (usually at 192.168.0.1 or 192.168.1.1) and enter the administrator username and password. Find the "WPS" or "Wireless" section. The current PIN will be displayed there. If the code has been changed previously, you can reset it to the factory default or generate a new one in this same menu.
Why does Windows say "WPS not available" when I try to connect?
This means that your Wi-Fi adapter or its driver doesn't support WPS, or it's disabled in Device Manager. This error also occurs if you're trying to connect to a network that uses a security type incompatible with WPS (although this is rare with modern WPA2/WPA3 standards). Try updating your network card drivers.
Is it safe to leave WPS enabled all the time?
For a home network with a strong password, the risk is minimal, but cybersecurity experts recommend keeping this feature disabled when not in use. This prevents any unauthorized login attempts through protocol vulnerabilities, even if they are theoretical.
Does WPS PIN work on Wi-Fi 6 routers?
Yes, WPS is compatible with all Wi-Fi standards, including 802.11ax (Wi-Fi 6). However, many new Wi-Fi 6 routers default to more modern setup methods, such as Wi-Fi Easy Connect (DPP), which replace classic WPS.
