HELP - Daily WAN disconnects

[Cang_Household]

DATA light went out should suggest the link is broken between the ONT and the router. I doubt your router would break the link, it should be your ONT breaking the link. Then why does the ONT break the link, maybe something related to low DC supply voltage or some interference.

Another outage through the night, similar logs.

What I changed this morning based on some feedback.

I was still using the old LAN cable from the G3100 to an Eero router. From the Eero router I had another line that I recently ran to a hub where I plug in my PC and Work laptop. The Eero serves my WiFi, I have WiFi disabled on the G3100. (I have tried removing the Eero and using the G3100 alone and vice versa. I only have the G3100 hooked up for the monitoring logs since this started)

NOW:

Bypassed all pre-run cables
I now have the ONT plugged into the G3100 on a new cable side by side.
New cable ran from the G3100 to the Eero router
Plugged the ONT into a new outlet (isolated, nothing else sharing the circuit)
My Work laptop and PC are now on WiFi not using any local pre-run LAN cables

Will monitor and report back.. thank you for the suggestions and support folks!!

I also see other local DHCP traffic in the logs during that outage window.

Update:

I had a 60 minute outage through the night which I'm hoping is related to the service call to look at the PON Line & Card. I haven't heard anything new to say for sure.

This afternoon I had a 30 min outage. During that outage the following lights were observed on the ONT
- All WAN lights dark, Red VID light illuminated.
- Then I had sporadic connection and the Red FAIL light was lighting up off and on

I have not had an outage like that before so may not be related to my initial issue. I haven't seen that there was a global outage.

Update:

Verizon replaced the PON Card yesterday afternoon when I experienced my last outage.

16+ hours of stability so far, looks promising. They no longer see any network errors as well.

Kudos to @Cang_Household (for the support on & offline and helping escalate), and to Alex @Verison_support for diagnosing and dispatching. Also big thank you to the community for all the suggestions and creativity.

That's wonderful.
