• 🔄 Change Wi-Fi channel - in the router settings (section Wireless mode) select a channel with minimal interference (for example, 1, 6 or 11 for the 2.4 GHz band).
• 📶 Switch to 5 GHz - If your TV supports this range (check the model's specifications), it will provide higher speed and less interference.
• 🔌 Upgrade your router antennas - replace standard antennas with more powerful ones (for example, TP-Link TL-ANT2408CL).

To check the signal level on your TV TCL:

1. Go to Settings → Network → Wi-Fi.
2. Click on the name of your network - a signal strength indicator will appear (usually in the form of bars or percentages).
3. If the level is below 30%, the signal is too weak for stable operation.

How to check for interference from neighboring networks?

Open the app on your smartphone Wi-Fi Analyzer (Android) or NetSpot (iOS). It will show all nearby networks and their channels. If your channel is overloaded, change it in your router settings.
