1. Preparation: What you need to know before changing your password

Before changing your password, make sure you have access to router admin panelFor this you will need:

• 🔌 Connecting to a router — via cable (recommended) or Wi-Fi. If you have already forgotten the current network password, connect via LAN port on the back of the device.
• 🖥️ Device with a browser — a computer, laptop, tablet, or smartphone. The main thing is that the browser is up-to-date (Chrome, Firefox, Edge).
• 📝 Login details — the router's default address, administrator login, and password. These are usually found on a sticker on the back of the device.

If the sticker is worn off or missing, try the standard combinations for Rostelecom:

⚠️ Attention: If you've previously changed your administrator login/password and don't remember them, you'll need to reset the router to factory settings. To do this, press and hold the button Reset (usually recessed into the case) for 10-15 seconds. After the reset, all settings, including the Wi-Fi password, will return to factory defaults.

2. Login to the router control panel

Open your browser and enter your router's IP address in the address bar (see the table above). If the page doesn't open:

• 🔄 Check that you are connected to the router (indicator LAN or Wi-Fi should burn).
• 🔍 Make sure you enter the address without http:// or www.
• 🛠️ Try a different browser or clear your cache (Ctrl+Shift+Del).

After successfully logging in, you'll see a login window. Enter your username and password (from the table or sticker). If the information is correct, the main settings page will open. The interface varies by model, but the navigation is similar.

4. How to create a strong Wi-Fi password

Weak passwords are the main reason home networks are hacked. Hackers use programs to guess simple combinations (for example, 12345678 or qwerty) in a few minutes. Follow the rules:

• 🔐 Length: minimum 12 characters (optimally 15+).
• 📛 Compound: a combination of uppercase and lowercase letters, numbers and symbols (!@#$%).
• 🚫 Exclude: dates of birth, names of pets, words from the dictionary.
• 🔄 Update: Change your password every 3-6 months.

Examples of strong passwords:

• KoT_2026!Vasya@WiFi (a mixture of words and symbols)
• 7#Tr0p1nK@-Rostelekom (replacing letters with numbers)
• P@ssw0rd_N3v3r_Gu3ss! (phrase with errors)

How to check the strength of a password?

Use free services like Kaspersky Password Checker or How Secure Is My PasswordThey estimate the time it would take hackers to guess your password. But don't enter your real password on untrusted websites!

If your router supports a guest network, set it up with a separate password. This will protect your main network from guest devices (such as their smartphones), which could be infected with viruses.

5. Common mistakes and their solutions

Even when following the instructions correctly, problems sometimes arise. Let's look at some typical situations:

⚠️ Attention: If your router starts rebooting frequently or disconnecting from the network after changing the password, overheating may be the issue. Check to see if the vents on the router are blocked and move the device to a more ventilated area.

6. Additional security settings

Changing your password is just the first step to securing your network. We also recommend:

• 🔄 Update the router firmware. Outdated versions contain vulnerabilities. Check the latest version in the section System → Software Update.
• 📡 Disable WPS. This feature simplifies connecting devices, but it's easily hacked. Find the option WPS in the Wi-Fi settings and deactivate.
• 👤 Change administrator login/password. Standard admin/admin known to hackers. Come up with unique data (for example, Rostelekom_2026!User).
• 🕵️ Enable MAC address filtering. Allow connections only to trusted devices (their MAC addresses can be found in the router settings).

7. How to reset a router if you forgot the administrator password

If you can't log into the control panel because you forgot your administrator login/password, you'll have to do hard reset (Hard reset). This will return all settings to factory defaults, including the Wi-Fi password.

1. Find the button on the back of the router. Reset (usually it is small and recessed into the body).
2. Take a paper clip or a toothpick, press and hold the button for 10-15 seconds.
3. Release the button when the lights on the router start flashing or turn off.
4. Wait 1-2 minutes for the router to reboot.

After reset:

• Connect to the router via cable or Wi-Fi (the network name and password will be standard, see the sticker).
• Log in to the control panel using the factory login/password.
• Set up your internet connection again (connection details can be found in your contract with Rostelecom).

⚠️ Attention: Resetting your router will disable all additional settings (port forwarding, parental controls, guest network). Write down important settings or take screenshots of your current settings beforehand.
