I have had my GC3 working just fine for a couple years.
About a month ago, I started getting some alerts on the panel like the following.
- Cellphone communication failure
- Broadband communication failure
I am able to arm/disarm from the panel and see sensor status. I am also able to see the sensor status on my phone, but I am not able to arm/disarm from my Alarm.com phone app.
I have run a “Network Test”, and it seems to complete successfully indicating a good connection to LAN, Internet, and Backend.
When I run a “Radio Status”, it says “cell radio module status not detected”.
I then removed the radio module, reinserted it, hoping either that or a system reboot would solve the problem. Nothing has changed.
What can I do to fix this?
