Adjusting the placement of your thermostat can have a significant impact on WiFi connectivity.

Try moving it to a more central location in your home, away from any electronics or appliances that may cause interference.

Use WiFi Extenders

If your home has a large layout or multiple floors, using WiFi extenders can improve your signal strength.

WiFi extenders boost the signal from your router, effectively extending your WiFi’s coverage area.

Optimize Your Router Settings

Check your router’s settings to ensure they are optimized for your ecobee thermostat.

For example, enabling QoS (Quality of Service) may prioritize network traffic to your thermostat, improving its WiFi connection.

Additionally, try changing your router’s channel to find one with less interference.

Reposition Your RouterPlacing your router in a central, elevated location can improve signal strength. Keep it away from obstructions, such as walls or bookshelves, that could limit coverage.
Upgrade Your RouterIf your router is outdated or not compatible with newer devices, consider upgrading to a newer model. Look for routers with multiple antennas, which can help improve signal strength and coverage.
Reduce InterferenceElectronics and appliances, such as microwaves or cordless phones, can interfere with your WiFi signal. Keep your router away from these devices and consider updating to a dual-band router to avoid 2.4GHz interference.

By following these tips, you can enhance your WiFi signal strength and improve your ecobee thermostat’s connection.
