Comcast split the incoming home cable into internet and TV services years ago. One lead goes to the modem and one lead goes to the DVR/Tivo. Always worked perfectly since.
My internet setup is coax directly into a Surfboard modem 6120 Docsis 3.0. Only 1 ethernet port is available and that goes into Apple Airport Extreme Wireless router(5th generation) WAN port. There are 3 gigabit ethernet LAN ports on the Extreme. I'm trying to use the output of one of those LAN ethernet ports into the ethernet port of the Tivo, but it's not working. I have got one of the ethernet LAN ports wired directly to my iMac and it works flawlessly. Could somebody please what I'm doing wrong or suggest something different to do?
It's not a matter of distance, my modem and my wireless are both 18 inches from my Tivo. Right now I've got the Tivo running on wireless, but occasionally for no reason, it just says it has no connection and just as quickly the problem will disappear. I want to use the ethernet connection if I can.
Can't for the life of me figure out the MoCA deal with my setup.
