All methods in this article are provided for legal use—restoring access to your network or connecting with the administrator's permission.

1. Connect via WPS (the fastest way)

WPS (Wi-Fi Protected Setup) — a technology that allows you to connect to a router without entering a password. It works on most modern routers (TP-Link, ASUS, Keenetic, MikroTik etc.). The essence of the method: press the button WPS on the router and select the network on the device within 2 minutes.

How to do it:

• 📱 On Android: go to Settings → Wi-Fi, select the desired network and press Connect via WPS (or WPS button).
• 🖥️ On Windows: in the list of networks, right-click on the desired one → Connect via WPS.
• 🍎 On iPhone/iPad: WPS is not supported - use other methods.

After that, quickly (within 120 seconds) press the physical button WPS on the router. It's usually labeled or combined with the reset button (hold it for 1-2 seconds). If the indicator WPS blinking - connection was successful.

There is a WPS button on the router (check the back panel)

The router supports WPS (usually indicated in the instructions)

The device has Wi-Fi enabled and is within range of the network.

Connection time is no more than 2 minutes after pressing the button-->

⚠️ Note: Some routers disable WPS after several unsuccessful attempts (brute-force protection). If this method doesn't work, reboot the router and try again.

2. Using a QR code to connect

Many modern routers (Huawei, Xiaomi, Tenda) generate QR code with your Wi-Fi connection details. This is convenient if you don't want to dictate a long password to guests. A QR code can be:

• 🖼️ Print and hang on the fridge (at home).
• 📱 Show from your phone screen (if your router supports code generation in a mobile app).
• 🖥️ Generate in the router's web interface (section Wi-Fi → QR code).

How to connect using a QR code:

1. Open the camera on your smartphone (or a special QR scanning app, for example Google Lens).
2. Hover over the code and a Wi-Fi network notification will appear.
3. Confirm the connection (the password will be entered automatically).

If you have iPhone, the QR code can be scanned via camera (in iOS 11+) or Control Center (hold the icon Wi-Fi). On Android Any scanning application will do.

Where can I find a QR code on my router?

On new models (Xiaomi AX3600, TP-Link Archer C6) The QR code is usually located on the bottom of the device next to the SSID and password.

If there is no sticker, go to the router's web interface (192.168.0.1 or 192.168.1.1), chapter Wi-Fi → QR code or Guest network.

In the manufacturer's mobile applications (for example, Mi Wi-Fi or Tenda Wi-Fi) The QR code can be generated in the network menu.

3. Connecting via saved networks (if the device was already on this network)

If your phone, laptop or tablet I've connected to this Wi-Fi network before., the password may have been saved in the system. Here's how to retrieve it:

📱 On Android (requires license root or ADB):

• Install the application Wi-Fi Password Viewer (For example, WiFi Password Recovery).
• Open the list of saved networks - passwords will be displayed.

🖥️ On Windows 10/11:

1. Open Settings → Network and Internet → Wi-Fi.
2. Click Managing known networks → select the desired network → Properties.
3. In the field Network password hidden text will be displayed - check the box Show entered characters.

1. Connect to the router via cable (Ethernet) or via Wi-Fi (if the network does not have a password or you remember the old code).
2. Open your browser and enter your router's IP address. This is usually:
   • 192.168.0.1 (For TP-Link, D-Link),
   • 192.168.1.1 (For ASUS, Zyxel),
   • 192.168.8.1 (For Tenda).

Enter your login and password (by default it is often admin/admin or indicated on the router sticker).

5. Connecting via a guest network

Many routers support guest network — a separate access point with limited rights (no access to local devices, such as printers). Often, a guest network:

• 🔓 Has a simple password (or no password at all).
• 📡 Turns off after a few hours.
• 🚫 Limits internet speed.

How to connect:

1. Ask your network administrator to enable guest access (if it's a cafe/hotel, the password is usually written on the receipt or at the reception desk).
2. Find the name with the prefix in the list of networks Guest (For example, Cafe_Free_Guest).
3. Connect using the provided password (or without it).

If you are an administrator, you can set up a guest network in the router's web interface:

Security → Guest Network → Enable
Network Name (SSID): MyGuestWiFi
Password: 12345678 (or leave blank)
Time limit: 2 hours

6. Connecting via the provider's app (for public networks)

It is often used in hotels, airports and shopping malls. authorization through the portal (captive portal). Instead of a password, you'll be asked:

• 📱 Enter your phone number and receive an SMS with a code.
• 💳 Pay for access with a bank card.
• 👤 Register via social networks (Facebook, VK).

How to connect:

1. Select a Wi-Fi network (e.g. Moscow_Metro_Free).
2. Open your browser - the authorization page will open automatically.
3. Follow the instructions (entering the number, agreeing to the rules, etc.).

If the page does not open, enter any address in the browser (for example, ya.ru) - the redirection will work automatically. On some networks (for example, MTS Wi-Fi or Beeline Wi-Fi) authorization takes place through the operator's application:

• 📲 Install the official app (My MTS, My Beeline).
• 🔍 Find the section Wi-Fi or Internet.
• 🔑 Connect to the network using the button in the app.

⚠️ Warning: On public networks Never enter passwords for important accounts (bank, email, social media) — your traffic may be intercepted. Use a VPN (for example, ProtonVPN or Windscribe) to encrypt data.

7. Alternative methods (for advanced users)

If none of the methods worked, you can try advanced methodsThey require technical knowledge and are not always legal (use only to restore access to your network!).

🔧 Resetting the router to factory settings:

• Click the button Reset for 10–15 seconds (until the indicators flash).
• Connect to the network with the factory name (indicated on the sticker).
• The default password is usually admin or empty.

📡 Intercepting handshake (for testing your network only!):

• Install Kali Linux or Wireshark.
• Capture authorization packets (requires someone to connect to the network).
• Decrypt the password using Aircrack-ng (for weak passwords).

📱 Exploiting WPS vulnerabilities (does not work on new routers):

• Apps like WPS Connect (Android) WPS PIN codes are brute-forced.
• Works only on older routers with WPS enabled and a weak PIN.
