C7000V2 - Spectrum Cable - every night resetting at same time
I have spectrum cable - ARRIS TM602G modem with C7000v2 nighthawk modem/router combo. Every night at 12:15AM my wifi goes off line for couple of minutes. My event Log shows: - Resetting t...
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?
Thanks,

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
