How to change the Wi-Fi password on an MTS router via TV: full instructions with details

Is it even possible to change the Wi-Fi password via the TV?

Modern Smart TVs from Samsung, LG, Sony or Xiaomi They're often marketed as universal devices for smart home control, including router setup. But in practice, the ability to change a Wi-Fi password via a TV depends on three key factors:

1. MTS router modelNot all devices from the provider support the web interface optimized for TV browsers. For example, older models ZTE H298N or Huawei HG8245H may display menus incorrectly or even block access from non-PC devices. New ones Sercomm RV6699 or Huawei EchoLife HG8045Q usually work correctly.

2. Browser on TVBuilt-in browsers on Tizen (Samsung), webOS (LG) or Android TV They're often limited in functionality: they don't support JavaScript, don't save cookies, or display input forms incorrectly. This can make it impossible to log in to the router control panel.

3. TV connection typeIf the TV is connected to the router via cable (Ethernet), the chances of success are higher—the web interface loads more reliably. When connecting via Wi-Fi, access to settings may be problematic due to the router's security restrictions.
