How to Fix Panel Communication Failure on the IQ Panel 4

Summary: If your IQ Panel 4 is displaying a "communication failure" or "radio not responding" message, it means your system is not communicating with our Alarm Response Center. Until communication is restored, we won’t receive signals for any alarm activity. Use the steps below to identify and resolve the issue. For further help, text 469.513.8685.

Common Causes and Solutions

1. Has Your Wi-Fi Name or Password Changed?

If you’ve recently updated your Wi-Fi credentials or replaced your router, follow these steps to reconnect your panel to Wi-Fi.

2. Power Outage

Ensure your alarm system has power. If you’ve experienced a prolonged outage, the system will reconnect automatically once power is restored.
If your panel battery is weak following an outage, allow up to 24 hours for it to recharge.

3. Loss of Connection to Power Source

Verify that your panel is securely plugged into a functioning outlet.
Test the outlet by plugging in another device to confirm it is providing power.

4. 3G Cellular Service Expired

3G cellular service was phased out in 2022. Learn more in our 3G LTE Update communication.
To upgrade your panel’s cellular module, text 469.513.8685.
Note: If your panel is connected to Wi-Fi, signals will still be received even without cellular service.

5. Local Cell Provider Outage

If there is a temporary cell service outage in your area, your system’s communication may be impacted. Ensure your panel is connected to Wi-Fi as a backup.

6. Signal Interference

Keep large metal objects or appliances that generate radio frequency away from the panel.
Position your panel near an exterior wall, above ground level, and away from interior closets or basements.

7. System Malfunction

To address a system malfunction, perform a power cycle:

Completely power down the panel and the module.
