The last two Fridays and today my base station has gone fully offline. When I check it no lights are on at all. To reboot it I have to unplug it and plug it back in. It loses all contact with the hardware in the house. If it’s armed before going offline it has no idea if a window or door is opened. It will not sound an alarm. It has me worried that I am losing my system each week. Any idea what might be the cause?
