Prone to what problems… guaranteed you've never actually tried Moca devices… ask the average Joe to pull Cat 6 throughout their house. How many you think will try? Pretty well every house has coax throughout their house. These MOCA devices use the existing RG6 to establish wired internet for those who do not have Ethernet cables throughout their house… or can't or won't wire their house with Ethernet.

Do research regarding MOCA standards… I use them to wire backhaul my ASUS ZenWIFI Pro ET-12's… I have ATT 2gb Fiber. I get over 2gb/s wired. My wireless speeds can reach around 1gb/s near my router that's wired backhauled via the MOCA device.
3W = 0.003 kW
0.003 kW/device * 2 (devices) * 24 (hours/day) * 365 (days/year) * 6 years = 315 kWh (for 6 years)
Average for US currently is 15.45 cents/kWh [energybot.com]:
315 kWh * 0.1545 $/kWh = $48.72

The max power the supply generates is 6 W, so it can be as much as double the above calculation, but usually supplies are over-spec'd, and assuming half the capacity (on average) seems a reasonable starting point.

So, yeah, you are spending a chunk of change on power as well. I can't conclude either way whether that cost is significant for each individual. Wholeheartedly agree, though, that maybe the $170 that one might spend is worth the effort of just pulling cat6 cable.
Veteran ISP network engineer with lots of MoCA experience here. I agree with everything you said with one exception: MoCA 2.5 is not a duplex communication system, it's still simplex ("half duplex") just like its predecessor versions and WiFi. We won't see duplex MoCA links until 3.0 hardware hits the market. The spec has been ratified but we're still waiting on MaxLinear to release chipsets so they can be embedded in next gen MoCA adapters. I'm looking forward to 10 Gbps symmetric throughput (probably more like 8.5 Gbps after error correction and other overhead just like XGS-PON) and don't mind the potentially shorter reach, much higher power consumption, and massive RF spectrum requirements that will likely come with it.

I'd recommend the frontier ones from eBay. I got those to help a neighbor get Internet in his workshop from his house. He had coax in his house and back to his shop. Worked great, only needed to get a moca splitter and filter at the house. These definitely have a place if you need them.

What does this device do? Is it like a powerline device?

Did you read the Amazon listing? It's pretty detailed with pictures and everything.

I bought those Frontier units a while back since I saw my house has those coax outlet (I am not the original owner). Unfortunately, I could not get the pair to connect. Even tried to connect to a few coax in the attic. Pretty sure there is a disconnect somewhere, but I'm no electrician. What would be the easiest way to figure out where the issue is? I really don't want to crawl up there.

Awesome! I'll finally be able to start my own coax network. Star or Token Right, Any thoughts?

Do they connect if you use a short coax cord between them? If so then could be the lines aren't actually connected in your house or there might be splitters causing issues.

That's not how these work, and I'm pretty sure you know that.

Yep,they can connect with a short coax cable between them, just not through the walls. I figured somewhere the cable is not connected, but can't tell.

Cool devices and definetely have a purpose but Id rather have one cat 6 line going since I can push 10gb through. Or really futureproof and run fiber

Or upgrade to moca 3.0 once it's more available. same coax

Klein tools has a coax cable tester which works like a circuit breaker finder...it tests continuity and also helps you trace which coax jack goes to which wire when they exit your house.

I've used MoCa on the flimsiest wire from the 70s that you could use as a jump rope, and the signal has held well. Length is the major issue, but have yet to see this be an issue at 200+ ft.

Quote from 56XNO :
They're all the same. Get the Frontier FCA252 and save your money.
One cool thing that sets the FCA252 apart from any other MoCA adapter I've come across is that it has a physical switch that allows you to select the RF channels you want to use, including the non-standard 400 - 900 MHz range which is useful if you already have something occupying the normal 1125 - 1675 MHz extended D band on your coax network like satellite TV signals. The 400 MHz - 900 MHz mode should also have longer reach, though I believe it's limited to only point-to-point operation (ie, two MoCA adapters total). Both bands provide ~2.5 Gbps usable bandwidth for all the connected adapters to share.

Got cheap moca adapters from eBay. Surplus ISP equipment for $25 each. I have a 500 mbps internet connection and get the full 500 mbps speed via wifi connected to the moca network.

Not all coax is the same quality, especially in houses that have older wiring installs. This obviously reduces speed, but worse is dropouts. Everything looks ok except no internet connection is tough to diagnose.

Great that it works for you, and sounds like many others. But it's not fool-proof for every house.
