Or perhaps you've come across advice to "enable WPS for a quick connection" but don't understand how it works or how secure it is? This technology truly simplifies connecting devices to Wi-Fi, but there are so many myths and warnings surrounding it that it can be difficult to figure out on your own.

In this article we will take a detailed look at what it is. WPS on TP-Link routers, how it works on popular models (for example, Archer C6, TL-WR841N or Deco M5), and why some experts recommend disabling this feature. You'll learn:

• 🔹 How WPS works - How does it differ from a regular password connection?
• 🔹 Step-by-step instructions to turn on/off on different models TP-Link.
• 🔹 Real security risks Why hackers like to attack WPS and how to protect yourself.
• 🔹 Alternatives to WPS - what to use instead for a fast and secure connection.

If you've been wanting to understand this topic but were afraid of pressing the wrong button, you've come to the right place. We'll explain everything in simple terms, without unnecessary technical jargon, but with an emphasis on practical nuances that will be useful in everyday life.

What is WPS and why is it needed on TP-Link routers?

WPS (Wi-Fi Protected Setup) — is a standard developed to simplify connecting devices to a wireless network. Instead of entering a long Wi-Fi password, you can:

• 📌 Press the button WPS on the router (physical or in the web interface).
• 📌 Enter your 8-digit PIN (if your device supports it).
• 📌 Use NFC or USB (less often).

On routers TP-Link This function is most often implemented through physical button (on the body) or virtual button in the control panel. For example, on the model Archer C20 The WPS button is combined with the power indicator, and on Deco X20 It can be activated via a mobile application.

The main advantage of WPS is Connect devices without entering a password in 1–2 clicksThis is convenient for guests, smart devices (such as printers or cameras) that don't have a keyboard, or when the Wi-Fi password is too complex. However, convenience comes at a price. potential security risks, which we will talk about later.

⚠️ Attention: Some devices (especially older smartphones or printers) may not support WPS. In this case, you'll have to use a classic password-based connection.

How WPS Works on TP-Link Routers: Technical Details

To understand why WPS is criticized for its vulnerabilities, let's look at how it works "under the hood." When you enable WPS on your router TP-Link, the following happens:

1. The router goes into connection standby mode (usually for 2-5 minutes). During this time, it actively scans for requests from devices that want to connect via WPS.
2. The device sends a request (by pressing the WPS button on it or entering the PIN code).
3. The router checks the legitimacy of the request and if everything is okay, automatically assigns a Wi-Fi password to the device (You won't see it, but the device saves it for future connections).

The key feature of WPS is the use of 8-digit PIN code, which by default often consists of numbers (for example, 12345670). This PIN is divided into two parts: the first four digits and the last four digits. The router checks them separately, which creates the main vulnerability.

On most routers TP-Link the mode is enabled by default PBC (button), and the PIN code can be disabled in the settings. However, even PBC is not without risks: if an attacker has physical access to the router, they can press the WPS button and connect to the network.

Step-by-step instructions: how to enable or disable WPS on TP-Link

The WPS activation process depends on the router model. We'll look at the three most common options: web interface, Tether mobile app And physical button.

Method 1: Via the web interface (for most models)

This method is suitable for routers TP-Link Archer, TL-WR and other series. Follow the instructions:

1. Connect to the router's network (via Wi-Fi or cable).
2. Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (the address may differ - look on the router sticker).
3. Enter your login and password (usually by default admin/admin).
4. Go to the section Wireless → WPS.
5. Activate the function with the switch Enable WPS.
6. Click Add a device and follow the prompts.

Make sure there are no other devices nearby that can connect|Make sure the PIN code is disabled (if not needed)|Note the WPS active time (usually 2 minutes)|Disable WPS after connecting devices-->

Method 2: Using the button on the router body

On many models (for example, TP-Link TL-WR840N or Archer C50) There is a physical WPS button. To connect the device:

1. Press and hold the WPS button on the router for 1-2 seconds until the indicator light starts flashing.
2. Within 2 minutes, press the WPS button on the connecting device (or select the network in its settings).
3. Wait until the indicator on the router stops blinking (connection established).

If the WPS button is combined with other functions (for example, with Reset), hold it for no longer than 3 seconds, otherwise the router will reset to factory settings.

Method 3: Via the Tether app (for Mesh systems and new models)

For routers TP-Link Deco or models with application support Tether:

1. Open the app Tether and connect to your network.
2. Go to the section More → WPS.
3. Click Enable WPS and follow the instructions on the screen.

⚠️ Attention: In some firmware TP-Link The WPS function may be hidden in the section System ToolsIf you can't find it, update your router's firmware.

WPS Security Risks: Why It's Often Disabled

Despite its convenience, WPS is one of the most criticized features in routers. The main complaints are related to PIN code vulnerabilities And time attacksHere are the key risks:

• 🔓 PIN code vulnerability: Because the PIN is checked in two parts (4 + 4 digits), a hacker only needs to brute force 10,000 + 10,000 = 20,000 combinations instead of 100 000 000 (for the full 8-digit code). This takes from several hours to days.
• 🕒 Time Attacks: If WPS is always enabled, an attacker can wait for you to activate the connection mode and hijack the session.
• 🏠 Physical access: Anyone who can press the WPS button on the router will have access to the network (for example, a guest or neighbor).

In 2011, the expert Stefan Viehböck published a study showing how WPS can be hacked 4–10 hours even on secure routers. Since then, many manufacturers (including TP-Link) have started to abandon the PIN code, but the function remains in most devices.

In practice this means:

• 📉 If you have weak Wi-Fi password, the risk of hacking increases significantly.
• 📉 In apartment buildings, WPS becomes easy target for hacker neighbors.
• 📉 Smart devices (cameras, light bulbs) connected via WPS can become entry point into your network.

Example of an attack on WPS

The attacker runs a program like Reaver or Wash, which brute-forces WPS PIN codes. Once a code is cracked, the program obtains the Wi-Fi password and connects to the network. The hacker can then:

- Intercept traffic (for example, website passwords).

- Infect devices on the network with viruses.

- Use your IP for illegal activities.

Despite the risks, WPS isn't always dangerous. If you:

• 🔹 Use it occasionally (only turn it on when connecting new devices).
• 🔹 Disabled PIN authentication in the settings.
• 🔹 Installed complex Wi-Fi password (at least 12 characters with letters, numbers and signs).

…then the risks are reduced to a minimum.

How to secure your TP-Link router if you use WPS

If you decide to use WPS, follow these recommendations to minimize the risks:

1. Disable PIN authentication:

   In the router settings (Wireless → WPS) find the option PIN Method and turn it off. Leave only the mode PBC (button).

2. Set WPS timeout:

   Some firmware TP-Link Allows you to limit the WPS activity time (for example, 1 minute instead of 5). The shorter the window, the less chance a hacker has.

3. Use a guest network:

   If WPS is needed for guest connections, create a separate one guest network with limited access to local devices.

4. Update firmware:

   Check for updates for your router regularly. TP-Link periodically releases patches for WPS vulnerabilities.

Extra tip: If you have Mesh system TP-Link Deco, use the WPS function instead TP-Link HomeShield - It allows you to connect devices via QR code, which is more secure.

⚠️ Attention: On some older models TP-Link (For example, TL-WR740N WPS vulnerabilities haven't been patched for routers (versions before 2018). If your router is older, it's best to disable WPS completely.

WPS Alternatives: What to Replace for a Quick Connection

If the risks of WPS bother you but you still want the convenience of connecting, consider these alternatives:

Method	How it works	Pros	Cons
WPA3-Personal	New encryption standard with simplified connection	High security, support on new devices	Not all routers TP-Link support
QR code (TP-Link Tether)	Connect by scanning a code in the app	Fast, safe, no risk of interception	A smartphone is required
Guest access via SMS	Generating a temporary password for guests	Limited access, no risk to the main network	Setup is more complicated than WPS
NFC (for supported models)	Bringing the device close to the router	Instant connection, high level of security	Rarely found on routers TP-Link

The most reliable option today is WPA3. If your router supports it (for example, Archer AX6000 or Deco X60), switch to this standard in the settings (Wireless → Security). It is not only more secure than WPA2, but also makes it easier to connect devices via Wi-Fi Easy Connect.

For older routers, the best alternative is guest network with a simple passwordGenerate a short but unique password (e.g. guest123!@#) and distribute it to guests. It's more secure than WPS and doesn't require complicated setup.

Common Errors When Using WPS on TP-Link and How to Fix Them

Even with proper configuration, WPS may malfunction. Here are the most common issues and their solutions:

• 🔴 The WPS button does not respond:

  Check if it is combined with ResetHold it for no longer than 3 seconds. If that doesn't help, reset the router to factory settings.

• 🔴 The device does not connect via WPS:

  Make sure that the router is in the enabled mode. PBC, and the device supports WPS. Restart both devices.

• 🔴 WPS indicator blinks endlessly:

  This indicates a malfunction. Disable WPS in the settings, reboot the router, and then turn it on again. If the problem persists, update the firmware.

• 🔴 WPS is enabled, but devices cannot see the network:

  Check if your network's SSID is hidden. Also, make sure that the router isn't in hidden mode. Isolation of clients.

If your internet speed slows down after enabling WPS, this is normal: the router is using resources to scan for requests. Disable WPS after connecting your devices, and your speed will return to normal.

⚠️ Attention: On some routers TP-Link (For example, TL-WR940N) After a reset, WPS may re-enable automatically. Always check its status after Reset.

FAQ: Answers to frequently asked questions about WPS on TP-Link

❓ Is it possible to hack the WPS on my TP-Link router?

Theoretically, yes. In practice, it depends on the router model and settings. Modern devices TP-Link (manufactured after 2020) are less vulnerable, but the risk remains. If your router is older than 5 years, it's best to disable WPS completely.

❓ How do I know if WPS is enabled on my router?

Go to the web interface (192.168.0.1 or 192.168.1.1) and check the section Wireless → WPSA blinking indicator on the router's body also indicates that WPS is enabled.

❓ Why isn't WPS working on my smartphone?

Many modern smartphones (especially on Android 10+ And iOS) do not support WPS for security reasons. Use the QR code in the app instead. TP-Link Tether or connect with a password.

❓ Can WPS be used to connect smart devices (e.g. cameras)?

Yes, but it's not recommended. Smart devices often have weak security, and if a hacker breaks the WPS, they'll gain access to your entire network. It's better to connect them through a separate guest network.

❓ How do I completely disable WPS on TP-Link?

Log into your router settings, go to Wireless → WPS and turn off the function with the switch. On some models, you also need to deactivate the option Enable WPS in the section System Tools.
