How to change your Wi-Fi PIN: detailed instructions for all router models

Forgot your Wi-Fi PIN or want to update it for increased security? Changing your wireless network's PIN (or password) is a standard procedure that can be completed in 5-10 minutes through the router's web interface. However, many users encounter difficulties: they can't find the right section in the settings, confuse the PIN with the WPA2 password, or don't know how to apply changes without disconnecting the connection.

In this article we will look at Step-by-step instructions for popular router models (TP-Link, ASUS, Keenetic, Zyxel, MikroTik), we'll explain the difference between a PIN code and a Wi-Fi password, and give recommendations on choosing a secure one. If you're worried about breaking something, don't worry: changing your PIN code won't affect your internet connection, and all changes are reversible.

Before you begin, make sure you have access to your router (admin panel login and password). These are usually found on a sticker on the back of the device or in the instructions. If you've lost the data, use reset instructions at the end of the article.

1. How is a Wi-Fi PIN different from a network password?

Many users confuse these two concepts, although they perform different functions:

  • 🔐 Wi-Fi password (WPA2/WPA3) — a security key requested when devices connect to the network. It encrypts traffic and protects against unauthorized access.
  • 📌 Wi-Fi PIN code — 8-digit code that is used for quick connection by technology WPS (Wi-Fi Protected Setup). It's used to connect devices without entering a complex password (for example, when setting up a printer or smart TV).

If you want to change exactly connection password (the one that guests or new gadgets enter), go to the section How to change your Wi-Fi passwordIf we are talking about a PIN code for WPS — read on.

⚠️ Attention: Technology WPS is considered vulnerable to brute-force attacks. If network security is critical (for example, in an office), we recommend disable WPS in the router settings and use only the WPA3 password.

Some modern routers (for example, ASUS RT-AX88U or TP-Link Archer AX6000) allow you to generate a PIN code automatically or disable it completely. In older models (for example, D-Link DIR-300) The PIN code is rigidly linked to the serial number of the device and does not change.

2. Where can I find the default Wi-Fi PIN code?

If you have never changed your PIN, you can find it out in one of three ways:

  1. Sticker on the router. Most manufacturers provide a PIN code WPS next to the serial number or SSID of the network. Look for text like WPS PIN, PIN Code or Default PIN.
  2. Router web interface. Go to your control panel (usually at 192.168.0.1 or 192.168.1.1) and find the section WPS or Wi-Fi Protected Setup.
  3. Documentation. The router manual (paper or electronic) sometimes provides a standard PIN code for the model.

Important: If the sticker contains an 8-digit code, but it doesn't work when connecting via WPS, the PIN was likely changed previously. In this case, it can only be reset through the router settings.

Manufacturer Where to find the default PIN Is it possible to change?
TP-Link Sticker on the back (near the SSID) or in Advanced → WPS Yes
ASUS In the web interface: Wireless → WPS Yes (can be disabled)
Keenetic Sticker or Home Network → Wi-Fi → WPS Yes
Zyxel On the menu Network → WPS (sometimes linked to serial number) Depends on the model
D-Link Usually tightly tied to the serial number No (reset only)

3. How do I change the Wi-Fi PIN code on my router?

The process of changing the PIN code depends on the router model, but the general scheme looks like this:

Connect to your router via cable or Wi-Fi|

Open the web interface (usually 192.168.0.1 or 192.168.1.1)|

Enter the admin login and password (default admin/admin)|

Find the WPS or Wi-Fi Protected Setup section-->

4. Save the settings (Save) and reboot the router.

🔹 ASUS (RT-AX, RT-AC, ZenWiFi)

1. Open Wireless → WPS.

2. In the section WPS PIN Code enter a new code or mark Disable WPS, if you want to disable the feature.

3. Click ApplyThe changes will be applied without rebooting.

🔹 Keenetic (Giga, Hero, Viva)

1. Go to Home Network → Wi-Fi → WPS.

2. In the field PIN code Please enter a new code or generate one automatically.

3. Click ApplyThe router will prompt you to reboot—confirm.

🔹 Zyxel (Keenetic, NBG)

1. Go to Network → WPS.

2. If the PIN is linked to the serial number, it cannot be changed. Otherwise, enter a new code in the field PIN.

3. Save the settings.

4. How to change your Wi-Fi password (not PIN!)

If your goal is to change connection password to the network (not the PIN for WPS), follow these instructions:

1. Log in to the router's web interface (see the sticker for the address and login/password).

2. Find the section Wireless, Wi-Fi or Network Settings.

3. Open the tab Security (Safety).

4. In the field Password, Key or Pre-Shared Key Enter a new password (we recommend using WPA3-Personal or WPA2-PSK).

5. Save the settings. All connected devices will be disconnected and will need to be reconnected.

⚠️ Attention: If after changing the password some devices (for example, Smart TV or IP cameras) stop connecting, check if they support the new encryption type (WPA3). As a last resort, switch back to WPA2.

For maximum safety:

  • 🔒 Use a password that is long 12+ characters with letters, numbers and special characters (for example, K@fe8-Lat7e$2026).
  • 📵 Do not use personal information (dates of birth, pet names).
  • 🔄 Change your password every 3-6 months.

5. Security Tips: Should You Use WPS?

Technology WPS was created to simplify the connection of devices, but has critical vulnerabilities:

  • 🕵️‍♂️ Brute-force attacks: The PIN code consists of 8 digits, but the last one is a checksum. In fact, only 7 digits (107 combinations), which allows you to pick up the code in a few hours.
  • 🔓 No blocking: Many routers do not block attempts to guess the PIN code, which makes the task easier for hackers.
  • 📡 Data Leak: If an attacker connects via WPS, they will gain access to the local network and can intercept traffic.

Recommendations:

  • Disable WPS, if you don’t use it (especially in offices or public networks).
  • ✅ If WPS is needed (for example, to connect a printer), change the default PIN to a random 8-digit code.
  • ✅ Use guest network for devices that require WPS (e.g. smart bulbs).
What to do if the router has already been hacked?

If you notice suspicious devices on the network (in the section DHCP Clients or Connected Devices), immediately:

1. Change your Wi-Fi password and WPS PIN.

2. Update your router firmware to the latest version.

3. Check the settings Firewall And MAC Filtering.

4. If you still have doubts, perform a full reset of the router to factory settings.

6. Common problems and their solutions

Problem 1: After changing the PIN code, devices do not connect via WPS.

Solution: Make sure that:

  • 🔄 The router rebooted after the changes.
  • 📶 The WPS function is enabled in the settings.
  • 🔢 The new PIN code was entered correctly (no spaces or letters).

Problem 2: I can't log into the router's web interface.

Solution:

  • 🔌 Check your cable connection (Wi-Fi may be disabled).
  • 🌐 Try alternative addresses: 192.168.1.1, 192.168.8.1, my.keenetic.net (for Keenetic).
  • 🔄 Reset the router using the button Reset (hold for 10 seconds).

Problem 3: The PIN code is not saved after reboot.

Solution: This could be a firmware bug. Update your router's firmware using the section Firmware Upgrade or System Tools.

⚠️ Note: Router interfaces may differ depending on the firmware version. If your screen doesn't match the instructions, check your device model and firmware version in the section Status or System Information.

7. How do I reset my router's PIN if I forgot my password?

If you can't access your router settings (forgot your admin login/password), the only way to reset the PIN is to reset the device to factory settings. To do this:

1. Find the button on the back of the router Reset (sometimes it is recessed and requires a paper clip).

2. Press and hold it 10-15 seconds (until the indicators start flashing).

3. The router will reboot with factory settings. Now you can log in to the control panel using the default login/password (usually admin/admin).

After reset:

  • 🔧 Reconfigure Wi-Fi (SSID and password).
  • 🔢 Change the WPS PIN if needed.
  • 🔒 Change your admin panel password to a complex one (not admin!).

FAQ: Answers to Frequently Asked Questions

❓ Is it possible to change the Wi-Fi PIN from my phone?

Yes, if your router has a mobile app (eg. TP-Link Tether, ASUS Router or Keenetic). It usually has a section WPS or Wi-Fi Settings, where you can change your PIN. This can't be done without the app—you need access to the web interface.

❓ What happens if I disable WPS?

Nothing critical: you won't be able to connect devices using a PIN code or the WPS button, but a regular Wi-Fi connection using a password will work as before. Disabling WPS is even recommended for increased security.

❓ Why does the router ask for a PIN code when connecting a new device?

This means that the device is trying to connect via WPSYou can:

  • Enter your PIN code (if you know it).
  • Press the button WPS on the router (mode PBC).
  • Disable WPS and connect using the standard Wi-Fi password.
❓ How do I know if my router supports WPA3?

Check the list of supported security modes in your Wi-Fi settings. If there is an option WPA3-Personal or WPA2/WPA3 Mixed, your router is compatible. Otherwise, update your firmware or use WPA2.

❓ Can I use one PIN code for multiple routers?

Technically yes, but that's extremely unsafeThe PIN code must be unique for each network, just like the Wi-Fi password. Reusing the code increases the risk of hacking.
