Weird MoCA problem

[Tarrant1701]

So I have Verizon FiOS, and my ONT connects to my Verizon Quantum Gateway/router via coax. I have Actiontec MoCA 2.0 adapters throughout the house, as I didn't want to run ethernet cables between the router and my other computers. This setup has worked well for a few years.

Then recently, I have been getting random problems on the MoCA network where any MoCA-connected device loses connectivity. On the router side, it says that the MoCA cable is disonnected and IP distribution is disabled. On the client side, my desktop says there is no LAN/WAN connection.

Oddly, everything else works. A computer connected by ethernet directly to the router still connects to the internet. A wireless AP connected by ethernet to the router also provides wireless clients connectivitiy. It seems it's on the LAN-side of the MoCA that drops out.

Rebooting the router usually (temporarily) fixes the problem. I swapped to a new router, and the same thing happens. I switched out the coax cable and splitter coming out of the tap to the router, and still have the same problem. It is so odd and frustrating!

Any other trouble shooting tips or thoughts?

It looks like you've covered some of my initial thoughts with the new cable and splitter and swapping the router. It seems like the next thing to try is unplugging each adapter one at a time to see if one of those is somehow causing a problem.

Yup, I've done that too. The thing is, the problem is so intermittent. I went on vacation for a week, leaving all MoCA adapters on and connected PCs/devices on. It stayed up for a whole week. When I returned, it went offline within 24 hours. It can stay stable for 2 hours or 48 hours. I've tried unplugging all adapters, even swapping them out one at a time, without any appreciable pattern.

And again what boggles me is, it only affects LAN-MoCa, WAN-MoCA is intact despite sharing some of the same the same cable paths.

i've had to replace a few MOCA power wall warts over the years. All are on filtered UPS now.
i would look to the power side. What is turning on/off when you are home versus when you were gone ?

I'm no expert on this... so here's what I'd do...

Given it was working and suddenly stopped working, I would try to isolate recent changes; coax cabling/terminator issues; pushed firmware updates from Verizon; and failing/damaged MoCA adapters/Ethernet patch cables/device NICs.

Well I had a mix of ECB6000 (non-bonded) and ECB6200 (bonded) MoCA adapters. Even though my FiOS G1100 router does NOT support bonding. Decided to replace all the 6000 units with 6200, and so far no disconnects. Been a few days and everything seems stable. Hopefully this solves the problem. Weird thing is, I could've sworn this setup was working perfectly fine until recently. I don't know if there was a firmware update to the router or not that caused this ... oh well!
