Modern Xiaomi TVs support many wireless connections, but the most versatile and stable option is Wi-Fi router communication, which allows you to broadcast the PC screen to the big screen, manage media and even use the TV as a second monitor without unnecessary wires. However, setting up such a connection often raises questions: why devices do not see each other, how to turn on the necessary protocols, or what router settings affect the quality of transmission.
In this article, we will analyze all the current ways of connecting - from the standard Miracast and DLNA We will focus on the settings of the Xiaomi router (or any other) that directly affect the stability of the connection: the choice of Wi-Fi channel, prioritizing traffic and turning off energy-saving functions. You will also find solutions to typical problems, from โno soundโ to โimage delayยป.
