This is more of a networking question, I realize, but it overlaps a great deal with some of the topics I've seen in this (great) community. I have a network whose topology is as follows: cable --> PoE filter --> splitter +--> TiVo Mini (so MoCA client only) +--> splitter +--> router (XFinity turd w/MoCA capability enabled) +--> TiVo Bolt (set up as MoCA client) That's two splitters. They are the Comcast-supplied 5-1000gHz ones. They are built like tanks. OK. The preferred MoCA network controller is my Xfinity disaster of a router. Fine. That means the TiVos are set up as MoCa clients. When the turd of a router doesn't crash or otherwise ruin my life, everything works great. Periodically, the router decides that MoCA is disabled for no good reason. Because I deliberately have my TiVos set up as MoCA clients (the Mini because it can be only a MoCA client and the Bolt because I don't want it to be the preferred network controller since the router ideally serves that purpose), that means they're both disconnected. Boo. Hiss. It occurred to me the other day that perhaps this is because the splitters are not MoCA compatible (i.e. they "quit" at 1000 instead of going "up" to 1675 gHz. So I ordered MoCA compatible ones and put them inline in the same spots. My internet bandwidth was DESTROYED by this move. I get about a third of the speed I was getting prior to the splitter swap. So I put the old ones back. My bandwidth came back. Anyone know what theory could account for this? Again, the only effective change is the gHz rating of the splitters; the db loss is 3.5 for them all.
