Modern wireless networks require reliable protection, and one of the key elements of this protection is PIN codeUsers often need to enter this code when trying to connect a new device via WPS or when logging into the router's administrative panel. Knowing where to find this code and how to activate it correctly can help avoid internet access issues.
In most cases, this digital key is an 8-digit sequence unique to each device. It can be found on a sticker located on the bottom of the router, next to the serial number and MAC address. If the sticker is worn off or missing, there are alternative methods for gaining access, which we'll discuss below.
Sometimes the security system requires changing the default value to a custom one, which significantly increases the security of your local network from unauthorized connections. The entry process may vary depending on the hardware model and the firmware version installed by the manufacturer. It is important to follow the steps carefully to avoid blocking access to the settings.
Find the PIN code on the router case and in the documentation
The first and most obvious place to look for the necessary data is the physical label on the device. Manufacturers such as TP-Link, ASUS or Zyxel, the factory PIN code is usually located on the bottom of the case. Look for a field labeled "PIN," "WPS PIN," or "Default PIN."
In some cases, the code may be hidden under a protective layer that must be carefully scraped off with a coin or fingernail. This is done to prevent thieves from reading the data in stores or during delivery. If the sticker is illegible, check the original packaging, which often contains all the technical information.
⚠️ Attention: Never take a photo of a sticker with public access to the photo, as attackers can use this data to try to hack your network.
If physical access to the device is restricted or the sticker is missing, the paper user manual often includes a separate page with factory data. Some manufacturers also place a QR code on the box that can be scanned to access the configuration.
- 🔍 Inspect the bottom of the router case in good lighting.
- 📦 Check the inside of the device box.
- 📄 Find the paper instructions or warranty card.
Using WPS for a quick connection
Technology Wi-Fi Protected Setup Wi-Fi Protected Setup (WPS) is designed to simplify connecting devices without having to enter a lengthy wireless network password. To activate this method, the router must have a dedicated button or software option. Entering a PIN code in this context occurs either on the connecting device or in the router's interface.
If you're connecting a wireless printer or repeater, for example, the device may request the router's PIN. In this case, you enter the 8-digit number from the sticker into the interface of the device you're connecting. Alternatively, some router models have a feature for generating a temporary PIN via the web interface.
How to find the WPS button on a router?
The WPS button is often combined with the Wi-Fi on/off button or the reset button. A short press (1-2 seconds) usually activates pairing mode, indicated by a flashing indicator light. A long press can reset the device, so proceed with caution.
The WPS connection process takes no more than two minutes. If a connection isn't established within this time, the security system automatically blocks the login attempt, and the process will have to be repeated. This protects the network from brute-force attacks.
☑️ Checking the WPS connection
Login to the web interface using a PIN code
Some ISPs and network equipment manufacturers use a PIN code as an alternative to a password for logging into the router control panel. This is common with carrier-issued devices, such as Sagemcom or SercommIn this case, the code acts as an authorization key.
To log in, you need to connect to the router's network via cable or Wi-Fi, open a browser and enter the IP address, usually 192.168.0.1 or 192.168.1.1The window that opens may ask for a "PIN Code" instead of the "Password" field. Enter the 8-digit number from the sticker.
If the default code doesn't work, it may have been changed during the initial setup of the device. In this situation, the only solution is a full factory reset, which will restore the original PIN code indicated on the label.
| Manufacturer | Standard IP | Entry type | PIN location |
|---|---|---|---|
| TP-Link | 192.168.0.1 | Password/WPS | Bottom of the body |
| ASUS | 192.168.1.1 | Password | Bottom of the body |
| Zyxel | 192.168.1.1 | PIN/Password | Back panel |
| Upvel | 192.168.10.1 | PIN code | Bottom of the body |
Setting up wireless network security
After successfully logging into your router settings, it's recommended to change the default security settings. Factory-set PIN codes and passwords are often known to hackers, so replacing them with unique combinations is a must. In the section Wireless or Wi-Fi Find WPS settings.
Here you can disable the WPS feature completely, which will increase security but will remove the ability to quickly connect using the push-button. If this feature is necessary, set a complex user PIN that will be difficult to guess. Save your changes by clicking "Apply" or "Save."
Don't forget to change the administrator password you use to access your settings. This will prevent unauthorized people from changing your network settings, even if they gain access to your Wi-Fi. Use a combination of letters and numbers, at least 10 characters long.
⚠️ Attention: After changing the WPS PIN code, all devices previously connected via this method will require re-authorization with the new code.
Modern routers with support Wi-Fi 6 Offer more advanced encryption methods, such as WPA3. These networks minimize the role of PIN codes in favor of more complex cryptographic keys generated automatically when scanning a QR code.
Troubleshooting code entry issues
A common issue is when the device displays "Incorrect PIN" even though you've entered the correct numbers. This may be due to the router blocking your PIN after several unsuccessful attempts. In this case, you should wait 1 to 5 minutes before trying again.
It's also worth checking your keyboard layout and case if the code contains letters (although the standard WPS PIN is usually numeric). Make sure you haven't confused the numbers 0 and O, or 1 and I, if they appear in the code. In some interfaces, letters and numbers look similar.
What to do if the code is not accepted?
Try entering the code without spaces. If you're using the virtual keyboard on your TV or set-top box, make sure the cursor is in the correct field. Sometimes, rebooting the router helps.
If the problem persists, try updating your router's firmware. Manufacturers regularly release updates that fix bugs in the WPS security module. You can download the latest version from the official website of your router manufacturer.
- 🔄 Reboot the router and client device.
- 📡 Check if there is a MAC filter on your router.
- 🛡️ Temporarily disable your antivirus software on your PC to check.
Factory reset
If you've forgotten your previously changed PIN or administrator password, the only option is to reset the router. There's a small hole on the router body labeled "Reset" or "Restore." Press the button inside with a thin object, such as a paper clip.
Hold the button for 10-15 seconds until the front panel lights flash simultaneously. This indicates the reset process has begun. After the reset, the router will return to factory settings, and the PIN code will be restored to the one on the sticker.
Check with your provider in advance for the required settings if they are not saved automatically.
⚠️ Attention: Do not interrupt the router's power supply during the reset process and subsequent boot-up, as this may damage the device's software.
After resetting, we recommend immediately changing the default PIN to your own to secure your network. Write the new code down in a safe place to avoid similar situations in the future. Regular router maintenance is essential for a stable internet connection.
Is it possible to change the WPS PIN to any code?
Yes, most modern routers allow you to set a custom 8-digit code in the wireless network settings. However, some older models may only require the factory code.
Where can I find the PIN code if the sticker is torn off?
If there's no sticker, try finding the code in the documentation or on the box. If the device is already configured, the code may be displayed in the web interface under the WPS status section if you have cable access.
Is it safe to use WPS with PIN?
WPS technology is considered vulnerable, as the 8-digit code can theoretically be brute-forced. For maximum security, it is recommended to disable WPS in your router settings and only use WPA2/WPA3 passwords.
