How to change the Wi-Fi password on a Rostelecom router via phone: instructions for 2026

Forgot your home Wi-Fi password or want to update it for security? You can do it right from your phone—no computer or complicated wiring required. Rostelecom offers routers from various manufacturers to its subscribers (Sagemcom, Sercomm, Huawei, ZTE), but the process for changing the password via a mobile device is standardized. In this article, we'll walk you through step-by-step how to access your router settings, find the wireless network section, and set a new security key—even if you've never set up the device before.

Important: all actions are performed through router web interface, not the Rostelecom app. The app allows you to manage tariffs and payments, but doesn't provide access to Wi-Fi settings. We'll use the standard browser on your smartphone— Chrome, Safari Or any other. If you have a Rostelecom router, but not a standard model (for example, purchased separately), the instructions will still work—the only differences are in the menu design.

Before you begin, make sure your phone is connected to the same Wi-Fi network whose password you want to change. If you've already disconnected or forgotten the old password, you'll first need to reset your router to factory settings (we'll cover this at the end of the article).

1. How to access Rostelecom router settings from your phone

The first step is to open router admin panel via a browser. To do this:

  1. Find out your router's IP address. Usually it is 192.168.1.1 or 192.168.0.1If these addresses don't work, check the sticker on the back of the device - it may indicate an alternative address (for example, 192.168.100.1 for some models Huawei).
  2. Enter the address in the browser's address bar. Do not use the search bar (for example, in Google) - only the address! Click Enter.
  3. Log inBy default, the login and password are admin/admin or user/user. If you have changed them, enter your data. On some routers (ZTE) the password may coincide with the serial number (indicated on the sticker).

If the page does not open:

  • 🔄 Check your connection — the phone must be connected to the Wi-Fi of this router (not via mobile Internet!).
  • 📱 Disable VPN or proxy - they can block access to the local network.
  • 🔌 Reboot your router - unplug the power cord for 30 seconds and plug it back in.

After successfully logging in, you'll see the main page of the web interface. The menu design varies depending on your router model, but the settings you need are always located in one of the following sections:

Router model Path to Wi-Fi settings Note
Sagemcom F@st 2804/3804 Network → WLAN → Security The menu is in English, but intuitive.
Sercomm RV6699 Wireless Network → Security Settings Russian-language interface, but may require a firmware update.
Huawei HG8245H WLAN → WLAN Basic Configuration The password is changed in the submenu WPA PreSharedKey.
ZTE ZXHN H298A Network → WLAN → Security SMS confirmation may be required (if two-factor authentication is enabled).

  1. Look for tabs with words Wireless, WLAN, Wi-Fi or Wireless network.
  2. Find the submenu inside the section Security (Safety), Password (Password) or Encryption (Encryption).

Rostelecom routers use WPA2-PSK (AES) encryption by default. Changing it is not recommended, as this is the most secure and compatible mode. If you see other options (such as WEP), select WPA2.
