Unfortunately, I cannot access the device at ALL via WiFi or directly connected via Ethernet so I am unable to get to the diagnostics at any time after if restarts.  However, Xfinity can see it briefly after it syncs and report that signal levels are within normal range.  I am currently using my older Arris Cable Modem and the signal levels are within range on that device as well so I don't think it's an ISP issue.  It's plugged into a UPS that is behind a line conditioner to ensure the power to it is as clean as possible and uninterrupted because I have frequent issues with power stability and line voltage at my location.

    How long have you had the modem for?

    Is this new issue that just appeared? 

    Something you may need to contact NG support about:

      I just opened a hardware support case with Netgear.  I have only had it just under 6 months.   The problem occurred 3 days ago just out of the blue.  I was streaming Youtube and lost Internet and assumed it was Xfinity but after spending an hour with their level 2 support we agreed it was most likely an issue with the Netgear and swapped to my old equipment which came right up.  

       

      Thanks for the assist though! I do appreciate it
