Did he also explain that the coax has higher latency? Left that bit out, didn't he? As for the higher bandwidth, it's specious. In theory, yeah, you could get something like 175 Mbps via MoCA, vs. 100 Mbps via the 100 Mbps Ethernet port on the ONT. Only... a) Verizon doesn't offer any service that fast, and b) they could just make it a GigE port instead, and you'd have 1000 Mbps capability on the Ethernet line -- not possible with MoCA AFAIK. The point of a MoCA installation is only to save the installers from having to run multiple lines -- one for data, one for video. You should not let them change an existing Ethernet installation to MoCA, and there is no reason for them to do so. BTW, the ONT swap (and it's ONT, not OTN -- it stands for Optical Network Terminal) was probably a waste; most likely, the only reason it fixed your problem is that the newer ONTs put out a signal that's not as "hot". You could've achieved the same result with an attenuator, which the installer should've known to try. But the Verizon-supplied boxes are more tolerant of "hot" signals than the TiVos, so what the installer's meter labels as "good" sometimes isn't, for TiVo.
