Which MoCa adapters work with FIOS?

I replaced my old router with a pfsense router, however the only way it will run is with the ONT switched to ethernet. With it switched to ethernet I lose data going to the STB making the TV pretty useless.

I bought a Motorolla MM1000 MoCa adapter to replace the Verizon ActionTec router with builtin MoCa. It does not work. Spent an hour with tech support, no luck. I read something somewhere that said there is a frequency that Verizon/Fios uses on the cable and it is not compatible with the Motorolla. Something to that effect. After a nearly an hour on chat with 2 different agent, they gave me no useful information on an adapter that will work INPLACE OF the old ActionTec router/Moca.

So my question is has anyone been successfuly in using their own MoCa adapter if so where did you get it, who makes it, model ...
