CM1000 and R7800 needs daily reboot
Lately on a daily basis our Optimum internet drops out , anywhere from noon to evening. only solution has been rebooting the modem but sometimes router as well. Modem is running fw 3.01.04 and router 1.02.90. Attached are the recent logs , based on the critical errors seems the modem could be the issue? Appreciate any assistance.
Thanks

So what do you recommend for a CM1000?
Might be worth trying that question here:
And check that it is compatible with your ISP.

yes, you logs are indicating line issues.
Got a screen snip of the cable connections page?
If you have any coax splitters, amplifiers, or signal attenuators, I'd recommend removing them.
Check your coax for kinks, damage, loose/old/bad/cheap connectors and remove them if you do.
Preferrably, directly connect the modem to where the coax line enters the home. This prevents wiring within the home from being the issue.
Thanks for the quick reply, cable connections attached. This suddenly started happening a couple weeks ago, before then only an occassional reboot. There was a splitter for the cable box but I removed that a few days ago since now only using internet. Barreled the two cables together. Using the stock yellow rj45 cable between modem and router which was two feet too long and coiled up. But again nothing has really change, other than the cold of winter . And come to think of it there is a grounding block the cable runs through outside. But if any wiring issue why inermitent?
More than likey its intermittent because the modem uses a range of channels. I'd be betting on interference/line issues on some of them. Reason I say this is while your levels are in spec for their actual power levels, (other than the non-locked channels) they're out of spec because they should be within 3.5dbmv of each other. Yours is out of this. You have some really weak channels and strong channels. So something is causing interference. And thats also giving you the power errors from your logs.
When you reboot/reset a modem, it sometimes pulls other channels. But those channels can change. So I'd be betting on the reboot is pulling in a good set and then its changing at some point to other channels and those have the issue.
