For several months, STB reboots at 9:48:07 PM. Not every day, but probably 3-5 times per week. Disrupts recordings in progress as well as live watching. Verizon online support interaction was completely worthless. Rebooting of modem or box has no effect. Location is in greater Boston, no idea if it is in a service area or just random.Any ideas on why? Anybody else with this problem?
