Pay special attention broadcast frequency. Modern Samsung Smart TV operate at a frequency 2.4 GHz And 5 GHz, but older models (before 2019) can only support 2.4 GHzIf your router broadcasts simultaneously on two frequencies with the same network name (SSID), the TV may "freeze" when making a selection. In this case, temporarily turn off 5 GHz in the router settings or assign different names to the networks (for example, MyWiFi_2G And MyWiFi_5G).

⚠️ Attention: If you use mesh system (For example, TP-Link Deco or Google Nest WiFi), make sure that the TV is connected to the main unit, and not to the satellite one. Some models Samsung do not work well with roaming between access points.
