Quick intro: If you changed internet providers or moved your router, the alarm may lose its path to the monitoring center. Here’s how to fix it safely.
Comm Trouble / Failure to Communicate on the keypad
No push notifications in the app, no new events in history
Power cycle your internet gear in this order: modem → router → (if separate) network switch. Wait 2 minutes between each.
If your communicator is cellular, make sure its antenna hasn’t been tucked into a metal can or closet—metal kills signal.
If the panel uses Ethernet, confirm the patch cable is fully seated and the router port light is on.
Run a Communication Test from the user menu (if your panel supports it).
Router replaced and the panel’s IP settings didn’t renew (DHCP change)
ISP blocked or changed port behavior; P2P cloud needs a refresh
Cellular antenna relocated behind metal shelving or appliances
Don’t factory‑reset the panel or yank wires. You’ll create new problems and wipe helpful logs.
When to call BBC Systems: Repeated failures after a clean reboot, cellular signal <2 bars at the panel, or you’re unsure whether you have IP, cellular, or dual‑path.
