Morning Boot Issue

Then what's the point of having a user controlled setting for update times with a default of 2:00 - 4:00 am?  I understand that in an emergency an update can be done at any time to restore service, but that seems to happen infrequently. 

For me this has been happening for about 1 year. I didn't start posting until I saw others were having the problem too. I found a posting from 3 years ago that may identify the problem as a signal quality issue that causes the receiver to not be able to connect to the Contour TV service during startup. So this isn't a total loss of a signal but more like static, low wattage, low frequency?  I'm assuming that when an overnight update is done it turns off or disables the DVR briefly and then it won't finish rebooting if there is poor signal quality at that moment. This would explain why it doesn't affect my neighbor and why it doesn't happen every morning or during the day. It would also explain why unplugging and replugging the DVR usually works on the first try (if the poor signal occurred hours earlier) but sometimes takes several tries (if the current signal still has poor quality). It could be the result of the cable wiring & connections inside my house or the Cox box on the telephone pole that sends the signal to my house (my neighbor is connected to a different pole). The Cox wiring in my house comes in at one end of the house and goes all the way to the other end where it connects to a a signal amplifier.  I remember the Cox installer ran it directly from the amplifier to the DVR without any couplings, splitters or other devices that could reduce or distort the signal quality.  But he had to split it somewhere, probably before the amplifier, to connect to the internet/phone modem.. The connections coming out of the DVR, such as the HDMI cable to the TV, wouldn’t cause disruptions to the incoming signal, correct?  I’ll crawl around in the attic and check all the connections but can live with the current annoyance (pun intended) as long as the DVR eventually comes on.

I haven’t had a daily update for 2 weeks and thus no morning rebooting problems. I changed the daily update time to 4:00–6:00 am PST and scheduled recordings every morning from 3:00-8:00 am. None of the recordings have been interrupted since I started this test. Two mornings ago (12/18/2022 7:55 am) a notice appeared that an update would be starting in 5 minutes and all devices would be shut down briefly. This was 2 hours past the scheduled time and I assume this must have been a special update of some sort. At 8:01 the update started and the DVR shut down but a mini-box in another room stayed on. The DVR rebooted itself 4 times before it came back on - - the welcome message on the screen would go dark and it looked like an error message flashed on the DVR where it displays the date. It finally succeeded at 8:29 am. I didn’t have to unplug it. As luck would have it this was in the middle of the soccer World Cup final. I wasn’t recording it but my neighbors did and theirs recorded without any gaps. Their line comes in from a different pole than mine. My experience for most of this year has led me to conclude that the rebooting problem is the result of an intermittent bad or week signal and unplugging the DVR, waiting 10 seconds, and plugging it back in usually fixes it in 15-30 minutes. Sometimes it takes a few more unplugging attempts. Only twice has it taken several hours. It’s the signal on the cable going into the DVR, not the cable going from the DVR to the TV which is usually off during the wee small hours of the morning when updates usually take place. My guess is it’s caused by climate change - - fluctuating humidity and temperature combinations that temporarily affect the cables and connectors in the attic or at the pole across the street which is the prime suspect when it takes a few hours to fix itself.
