re: Cord cutting question: Ethernet and Coax

MoCA works great and current generations are far in excess of what you'll ever use and is on par with current generations of Ethernet , but you need to do your homework to make sure you aren't mixing frequencies.

OTA and MOCA can even be carried on the same line. Just don't mix OTA with your cable internet line.

If you aren't personally invested in a particular setup, TiVo works amazingly with this. I have a base unit with a tuner (Bolt specifically, but there are other options) tucked away in my closet with my modem and NAS. Then I have TiVo minis at all usage locations, connected by coax.

Through it, they get both local streaming from TiVo recordings and PLEX, plus wired Internet so I don't clog up my wifi. OnePass is also really nifty in that if you record one show, and you want to keep watching and Netflix has it, it will integrate the two. Going on if you binge watch into the next season which only Hulu has.

Power line networking sucks. If it works for you, great. But it's by no means as easy as it's often shown.

And I have reason to believe that modern wiring with the new ARC breakers are incompatible with them.
