What to do if Lennox iComfort E30 Thermostat has insufficient signal strength?
- BBrian KleinJul 27, 2025
If your Lennox Thermostat shows insufficient signal strength because the RSSI signal strength is outside the range of -9 to -69, you can try to relocate the router closer to the thermostat, add a repeater, or move the Smart Hub. Also, adjusting antennas on the router and/or Smart Hub may resolve connectivity issues.
