Maybe the wrong board, but I figured Id try here first.

I have ditched Uverse in favor of Playstation Vue and thus far have been mostly pleased with the results. I am running Vue to 3 TVs. 2 FireTV and 1 Firestick. All are connected via WiFi. As I said, mostly positive results but occasionally I am getting some lag while watching live TV (occasionally Netflix as well) that I can only guess is due to the connection/speed of the WiFi. Im sure a wired connection would be much more reliable.

My question is this, I already have coax ran to the TV areas Im concerned about. Is there a way to run ethernet through the existing Coax that is reliable and would be better than my WiFi connection. Or would I have to replace the coax with a dedicated ethernet cable as that doesnt seem to be a feasible option for me.

Anyone with any experience with this would be greatly appreciated.

Ethernet (CAT-5) and Coaxial cable are two totally different cables.

This is probably tech board stuff, but you could always use something like this. You plug one ethernet cord to your router and then into the wall, and then where your TV is you have one that plugs an ethernet cable into the fireTV. Of course, it wouldn't work with the firestick since there's no ethernet port, but it would work with the FireTVs.

This isn't the exact one we have, but the one we have seems to work faster than the wifi in our house. I'm sure a lot depends on which unit you buy, but I'd give this a shot and see if it helps.

After doing a bit more research, Ive seen the powerline adapers but they also make a coax adapter that seems to be superior but its also alot more expensive and requires more setup.

Not sure what I'll do here. Maybe just roll with it and pray I have no issues during football season.

I strongly recommend against the powerline adapters. They have short lifespans and a client approached us to install wiring because of how often they had to replace them.

If you want the best for this, get on Cat6 (or at least Cat5e) and wire the house to the TVs. WiFi is great, but the larger the bandwidth needed (say, gaming or running HDTV at high resolutions for extended periods) will lead to dropped packets that will cause lag in your display.

Make sure your internet connection is sufficient as well. If you have 4 TVs on at once all streaming HDTV, then a 25Mbps connection probably won't cut it. If there's Gigabit fiber as an option, get that and wire the home for Cat5e/Cat6. With that many devices wired, if you also have PCs, you may need something with 8+ ports.

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.
