Advertisements I understand what you're advising, but other persons suggest that FIOS is somehow different and that if my TV signal from Frontier Communications is terminated (retaining ISP service) I can still use the existing COAX in my walls to send signal to other rooms via my Verizon router/bridge. TiVo Customer Support examined my Roamio remotely and said all I have to do is remove the cable TV COAX from my Roamio COAX input and screw in my antenna COAX and I'm all set - signal to the whole house and everything. My ethernet line from Roamio to the MoCA adapter would do the networking job......they say... On the other hand, if I completely isolate my FIOS COAX, then a second bridge would have to be installed and I've been advised against doing that. I believe the dispute (and my confusion) is based upon whether MoCA is designed to transmit an rf signal via COAX or whether its designed to transmit an ethernet signal via COAX. If our attention is paid to rf via COAX, then frequency issues arise. If our attention is paid to ethernet via COAX, then frequency issues shouldn't be a problem. But that's as far as my addled brain can go today..... thanks for everyone's help.
