Changing your home Wi-Fi password is a basic security procedure that users often put off. However, if you suspect your neighbors are accessing your internet, or simply want to strengthen the protection of your personal data, you need to update your access key as soon as possible. The standard scenario involves using a computer or smartphone, but what if you don't have a laptop or mobile device with a working internet connection? In such situations, modern security solutions come to the rescue. Smart TV, which are actually full-fledged computers with a large screen.
Using a TV to access your router settings Rostelecom It has its advantages: the large screen allows you to see all input fields and menus in detail, which is especially important for people with visual impairments. Furthermore, the TV's built-in browser or a specialized ISP app may be the only way to administer the network if other devices are blocked or unavailable. In this guide, we'll cover all the details of the process, from connection to final encryption setup.
Please note that the router's web configurator interface may differ depending on the device model (Sagemcom, ZTE, Eltex, Sercomm). However, the operating logic remains the same for all modems provided by the provider. Internet gateway — This is the control center of your local network, and it is accessed via a standard IP address, which can be found in the documentation or on a sticker on the bottom of the device.
Preparing equipment and checking connections
Before changing security settings, you need to ensure your TV is physically connected to the router. It's crucial for the password change process to be completed while the device is on the network, even if the internet connection is temporarily down. You can connect in two ways: via cable. LAN or via wireless signal Wi-Fi.
If you are using a wired connection, simply plug the Ethernet cable into the appropriate port on your TV and into any of the yellow ports LAN on the back of the router. This will ensure the most stable connection, preventing interruptions while saving settings. When using Wi-Fi, make sure the TV is connected to the network whose password you plan to change.
⚠️ Note: When changing the router password, the TV's current Wi-Fi connection will be disconnected immediately after the new settings are applied. If you are changing the password for a network connected over the air, you will need to perform further steps (testing the network) from another device or re-enter the new key on the TV.
It's also important to check that the router itself is working. The indicators on the front panel should be green or blinking. If only the power indicator is lit, the device may be frozen and needs to be rebooted. To do this, press the power button on the back panel or briefly unplug the power supply.
☑️ Ready to customize
Find the gateway address and log in to the control panel
To access your router's settings, you need to know its IP address. In most cases, this is the IP address for your equipment. Rostelecom the standard address is used 192.168.1.1 or 192.168.0.1This information is often duplicated on the factory sticker located on the bottom of the device case, next to the fields SSID (network name) and WPA Key (default password).
Open the built-in browser on your Smart TV. Depending on your operating system (Android TV, Tizen, webOS), the interface may be called "Internet," "Web Browser," or "World Wide Web." Enter the router's IP address in the address bar. If the address is correct, the system will request authorization.
Login and password are required to access the admin panel. By default, devices Sagemcom, ZTE and other provider models often use combinations:
- 🔑 Login:
admin, Password:admin - 🔑 Login:
admin, Password:1234 - 🔑 Login:
admin, Password: (indicated on the router sticker) - 🔑 Login:
superuser, Password:admin(for some Eltex models)
If the default data doesn't work, it may have been changed previously. In this case, you'll need to reset the router to factory settings using the button. Reset, which will restore access to the control panel, but will delete all user configurations.
What should I do if the TV browser doesn't open the router page?
If the page isn't loading, check if Incognito mode or a proxy server is enabled on your TV. Also, try clearing the browser cache in your TV settings. Sometimes built-in browsers on Smart TVs don't handle older router security protocols well. In this case, using the "Home with RTK" app (if available on your platform) or connecting a keyboard and mouse to the TV for more precise data entry can help.
Navigating the Rostelecom router interface
After successful authorization, you will be redirected to the modem's web interface. Interfaces may vary between models, but the menu structure is generally the same. Find the section responsible for wireless networking. Look for the tabs with the following names: WLAN, Wireless, Wi-Fi or Wireless network.
There is often a submenu within this section. Security (Security) or WLAN SecurityThis is where the encryption and password settings are located. In older firmware versions, the path may look like this: Network → WLAN → SecurityIn more modern interfaces (for example, in routers Sagemcom F@st 2804 or RT-PM-01) settings can be moved to a separate tab "Wi-Fi Settings".
Pay attention to the field WPA Pre-Shared Key or simply PasswordThis is the field where the current password is stored. To change it, you need to erase the old characters and enter a new combination. Don't forget to also check the encryption type—it should be set to WPA2-PSK or WPA3 for maximum protection.

If you've changed your admin panel password and forgot it, your only option is to reset the router to factory settings. To do this, press and hold the button Reset on the device's body (usually 10-15 seconds) until the indicators flash. After that, use the information on the sticker on the bottom of the router.
Do I need to change the network name (SSID) when I change the password?
Changing the network name is not required, but it's recommended if you want to be sure all devices reconnect with the new password. If you leave the name the same, some devices may try to connect with the old saved password and return an error.
Is it safe to change router settings via Smart TV?
Yes, it's safe, as the connection is within your local network. However, make sure the TV itself has the latest security updates to eliminate the risk of data interception by malware if it infiltrates the system.
What is considered a strong password for Wi-Fi?
