We'll also tell you how to create a secure password to prevent hackers from breaking into your network.

Important: The procedure depends on the model of your router (Sagemcom, Sercomm, Huawei etc.) and connection type (GPON, Ethernet, ADSL). If you have optical terminal (For example, Huawei HG8245H), some settings may be hidden in the ONT menu. But don't worry—we'll describe each step in detail, taking into account the nuances.

Before you begin, please check:

• 🔌 The router is connected to the network and the indicators are lit steadily (without blinking).
• 💻 You have a device (PC, smartphone, tablet) connected to this network via cable or using the old password.
• 📄 Login details for your personal account Rostelecom (login is usually the contract number or phone number, password is from the SMS during registration).

1. Change your password through your Rostelecom personal account

The easiest way is to use provider's web portalIt is suitable for most tariffs, except for corporate subscriptions and some older contracts. These instructions are valid for the 2026–2026 personal account.

Steps:

1. Open your browser and go to lk.rt.ru (or start.rt.ru for new clients).
2. Enter your login (phone number or contract number) and password. If you don't remember your password, click "Recover"—you'll receive a code via SMS.

5. Save the changes by clicking the "Apply" or "Save" button.

⚠️ Attention: After changing the password through your personal account, the router can reboot automaticallyAll devices will be disconnected from the network, and you'll have to reconnect with a new password. If you have connected smart devices (cameras, speakers), they'll also need to be reconfigured.

The new password is at least 8 characters long|It contains letters, numbers, and special characters|The password does not match your personal account login|Did you write it down on paper or in a secure password manager?

If the "Wi-Fi Settings" section is missing from your personal account, it means:

• 🔹 You have outdated router model (For example, D-Link Dir-300), which does not support remote control.
• 🔹 The tariff does not include the "Wi-Fi Management" option (applicable to some regional offers).
• 🔹 Connection is made via intermediate equipment (for example, a switch in the entrance).

What should I do if my personal account won't open?

If the site lk.rt.ru It doesn't load, check:

1. Ad blocker - turn it off (especially if you use AdGuard or uBlock).

2. VPN - some services (for example, ProtonVPN) may block access to Russian resources.

3. Browser cache - clear it or try opening the page in incognito mode.

4. Other device — sometimes the problem lies in the local settings of the PC/smartphone.

If nothing helps, try logging in via the mobile app Rostelecom (see section 3).

2. Changing the password via the router's web interface

If your personal account is not suitable, you can go to router settings directly. This method works for all models, but requires knowledge of the device's IP address and login data (admin login/password).

First, determine Router IP address:

• 🖥️ On Windows: open command prompt (Win + R → cmd) and enter:

  ipconfig /all

  Look for the line “Default gateway” - this is the router IP (usually 192.168.1.1 or 192.168.0.1).

• 📱 On Android/iOS: use apps like Fing or Wi-Fi Analyzer.

Now connect to the router:

1. Open your browser and enter the IP address in the address bar (e.g. http://192.168.1.1).
2. Enter your login and password. Standard combinations for routers Rostelecom:

   Router model	Login	Password
   Sagemcom F@st 2804	admin	admin or empty
   Sercomm RV6699	user	user
   Huawei HG8245H	telecomadmin	admintelecom
   Eltex NTU-RG-1402G-W	admin	eltex

3. If the default data doesn't work, the password has already been changed. Try finding the sticker on the router body or follow these steps: factory reset (button Reset on the back panel).

Next, go to the Wi-Fi settings section. The path depends on the model:

• 📡 Sagemcom: Network → WLAN → Security
• 📡 Sercomm: Wireless → Basic Settings
• 📡 Huawei: WLAN → WLAN Basic Configuration

In the field Password, Pre-Shared Key or WPA Passphrase Enter a new password. We recommend:

• 🔐 Use at least 12 characters.
• 🔤 Combine uppercase and lowercase letters, numbers and signs (!@#$%).
• 🚫 Avoid obvious combinations (12345678, qwerty, dates of birth).

⚠️ Attention: If you see in your router settings two networks (For example, RT-WIFI_2.4G And RT-WIFI_5G), change the password for both! Otherwise, one of the networks will remain vulnerable.

1. Restart the device (turn off the power for 30 seconds).

2. Use a different browser (Firefox or Edge instead of Chrome).

3. Disable your antivirus—it may be blocking changes to settings.-->

3. Changing your password via the Rostelecom mobile app

7. Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when changing their password. Let's look at the most common ones:

Error 1: Changing the password for only one frequency network (2.4 GHz or 5 GHz).

• 📶 Many routers broadcast two networks at the same time. If you changed the password only for RT-WIFI_2.4G, That RT-WIFI_5G will remain with the old key.
• 🔧 Solution: Check the settings of both networks in the router's web interface.

Error 2: Using spaces or Cyrillic characters in the password.
