How to connect a second TV to Rostelecom via Wi-Fi: a complete guide with all the details

Connecting a second TV to Rostelecom's interactive TV via Wi-Fi — a challenge many subscribers face when expanding their home media system. Unlike a wired connection, a wireless connection requires consideration of the router, TV model, and data plan. In this article, we'll cover every step: from checking equipment compatibility to fine-tuning the network for stable, lag-free streaming.

However, with the help of modern Smart TV, Android TV boxes or functions Miracast/DLNA You can stream to a second screen without purchasing additional equipment. We'll cover all possible scenarios—from using your TV's built-in features to setting up rebroadcasting via a router.
