    Either rent spectrums router for ridiculous monthly charge or get my own - which I did with the nighthawk.   Worked fine for about 6 months, till recent issue.

      so you're not using the other modem? Just the c7000?

      Do you have a screen snip of the cable connections page and the modem event logs?

          Happens at exact same time every night.

         

        2) On the setup  -  the   spectrum TM602G is used for Telephone service - coax from wall is split (commscope SV-2G splitter)  to this modem alogn with power and phone line . 

         

        & Netgear nighthawk for internet is connected to coax/power.    Then WIFI to  laptops, etc. 

         

        Previously I had  seperate Netgear router and separate netgear modem -  in JUne of 2020 - I replaced these 2 with the Netgear Nighthawk C7000V2 combo -   no issues for about 8 months , only the last month or so  -  at exactly 12:15AM -  I get this eve
