Daily Gateway Resets

• As a prelude, I should note that I have dealt with Xfinity CS multiple times over the last week with the same result: being told it was fixed on the backend (no indication of what was fixed) and it has yet to actually be fixed. I had a service appointment canceled because CS told me it had been escalated and fixed on the back end. 
  
  The problem: My Gateway (XB8) resets around 3 am every night and takes upwards of an hour to complete whatever it's doing. During this time, my VOIP phone, television and automated systems (Google Nest and Hue Light system mostly) go off line.
  
  As mentioned above, I have had the system remotely analyzed and it has been found to be OK. Additionally, there have been no local outages reported that match to the times I see. A technician call was scheduled but cancelled when told it was fixed on the back end. It was not fixed. I initiated a second ticket which was passed to an escalated team and I all I got was a text saying it was fixed -again, it was not fixed.
  
   A few things:
  
  
• What it the assumed root cause of this daily interruption of service? Clearly the service team thinks they know what is wrong and think they have fixed it.
• I would like a detailed explanation. My assumption is that this is either a known flaw in the device or an automated process that is being initiated on the backend.
• I would like to speak to someone who can discuss this issue with me instead of ghosting me and closing the service ticket without verifying the fix.
• Until this is resolved, I would like my bill pro-rated to reflect the daily down time. I pay for 24-7 internet
  
  

I am grateful I have not taken advantage of the Xfinity home security systems. Imagine having a security  system that goes down on a daily, predictable timeline?
