RBK53 Reconnect Issue with Spectrum new modem

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.

If I lost internet, the modem and Orbi router would reconnect just fine after internet was restored. In June '21, Spectrum informed me I "must" upgrade to DOCSIS 3.1 or I would lose my internet access. They provided a no-name "Spectrum" modem at no cost. The modem is overly sensative to power and connection issues but aside from that, works reasonably well. However, when internet connectivity goes down, the modem will reconnect once internet is restored but the Orbi will not. I MUST reboot the Orbi to re-establish my wifi network.
If I upgrade to a Netgear DOCSIS 3.1 modem (CM1000 or Nighthawk), will my restoration issue be fixed (Reconnections were not an issue with the CM600)? I have seen discussions of reconnect issues with a Nighthawk on these boards.
Or, is there a way to make the Orbi system reboot automatically when a loss of internet connection is encountered? That may be a quick solution while I research purchasing another Netgear modem.

"service box" may be ambiguous. Anyone who subscribes to cable TV and internet will have at least one splitter between the coax tap at the main cable line and their router. When I was running MoCHA through my cable wiring, there was also a splitter for the MoCHA box. (Tivo's come with an internal MoCHA tap inside the chassis.)
Also, I had neglected to inquire about telephone service (which I get through my Spectrum provided modem). Although compatible with Spectrum, the CM1000 and CM1100 are not compatible with voice service from Spectrum.

I had the house wired with good RG6 when built. There is a splitter used but it's basically a coupling, one in/one out directly to the modem. ISP has theoretically checked the signal and tells me all is OK. Power was out for 9 hours, restored, modem booted and router didn't automatically reconnect. I think it's the generic modem and nothing else.
