I have a Roamio plus and two minis. I just moved and can’t seem to get the right configuration -I had them working at my previous home, but in my new home I have Spectrum with a modem and a router instead of the all in one option with Cox. I can seems to get the right set up from the wall thru modem, router, bridge, cable box, and main TiVo. I also have a POE at my cables starting point. Help?
