Advertisements Our equipment: Arris Modem - supplied by TWC , no MoCA TWC set top box with cable card Netgear N600 wireless router Legrand MoCA adapter TiVo XL4, mini, Roamio Antronix 5-1003mhz splitters POE filter We have been trying to get MoCA up and running for a week. In Family Room POE is installed before the splitter in the cable box Coax is connected to MoCA adapter (cable in) Adapter connected to modem by coax (tv out) Adapter connected to router by Ethernet TiVo XL4 connected to router by Ethernet and by coax to incoming cable via splitter (set up by TWC) In Master Bedroom TiVo mini This set up actually worked for about 5 minutes. Then we decided to move the mini to another room and it all fell apart, even when we put it back. The mini can't find the TiVo XL4 When the Ethernet cable is connected from the router to the MoCA adapter we lose Internet. We have tried splitting the incoming cable between the MoCA adapter and the modem, but that doesn't work either. We are very frustrated and are starting to consider the suggestion on a previous thread to have TWC come in and install their whole house DVR and then trade it for the TiVos. I really feel that TiVo sucks you in by making it seem simple to set up MoCA. It's not.
