MoCa not working with new ONT

New ONT I-211M-L yesterday and MoCA no longer works between TiVo Central and TiVo Mini's. MoCa coax output of prior ONT was split; one coax to TiVo's (via another splitter) and one coax to Router MI-424-MR. The Router Ethernet CAT-5 cables were the output to computers, etc. Despite only 50/50 service, we had no problem recording one program on TiVo Central while watching two different programs on remote TiVo Mini's. Now I can't even watch live TV or a previously recorded program on one remote TiVo Mini. Do I need a new Router? What is the proper configuration for TV MoCA network on one hand and computer Ethernet network on the other hand? Verizon said I can only have one or the other; I don't know if that reference was to the ONT or the Router. At this point I want my old ONT back!

This is a basic wiring diagram for the way Fios likes to be setup:

You should check the splitters and their connections to make sure nothing is wired incorrectly, has come loose or if the splitters have gone bad. Also you may need MOCA 2.0 certified splitters with the new ONT. You could add a second splitter into the line out from the first splitter that feeds the cable box if you need more MOCA connections.

Thanks for quick reply. Surprised to see both coax and CAT-5 connections to router in your diagram as just the MoCa should be sufficient (for lower speed service), so my CAT-5 connection isn't needed now. Anyway, your diagnosis of old Splitters not working with the new ONT was correct. New (six-way) splitter solved the problem. I understand that I'll need changes if I go over 100 Mbps. Thanks again.

Glad you solved your problem.
