On Ecobee, go to Settings > WiFi. Forget current network and reconnect. Enter password carefully - it is case sensitive. Avoid copy-paste errors.
Check Signal Strength
Ecobee shows WiFi signal bars. If only 1-2 bars, signal is too weak. Move router closer or add WiFi extender near thermostat location.
Power Cycle Network
Unplug router and modem for 60 seconds. Plug modem first, wait for connection. Plug router, wait 2 minutes. Then reconnect Ecobee.
Reset Ecobee WiFi
On Ecobee, go to Settings > Reset > Reset WiFi. This clears saved networks. Reconnect fresh to your 2.4GHz network.
