How can I troubleshoot a "STB MNC Play Error" related to my internet connection?

Begin by restarting your modem and router. Check your internet speed by running a speed test on a device connected to the same network. If the speed is significantly lower than expected, contact your internet service provider. Ensure your STB is connected to the internet via a stable wired or wireless connection. Consider moving the STB closer to the router or using a Wi-Fi extender if the wireless signal is weak.
