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.

Second this

Been using Moca for 3.5 years in an 8k sq foot two story house. ATT fiber 1gb up/down. I max this at every device throughout the house. Never had as much as a hiccup. Plug and play from day 1. Two wireless APs max as well. I could've spent a week or two crawling through the attic wiring up a dozen rooms. This took 25 minutes.

Get the frontier… same speeds at half the price…

Quote from barbedwiredave :
I have attic space on the 3rd floor and a finished drywall basement, can you come show me what spaces I can crawl into so I can pull Cat 6? On the topic of moca adapters, I do use a different brand but they work flawlessly providing my full internet line speed of 1.3GB with little fuss. The only downside i have encountered is approximately 3ms of additional latency.
OP lives in a teepee. I had 3 ethernet drops installed in my home recently. No way anyone is going to "fish" ethernet through studs without drilling holes.

can you elaborate and/or share a link to this? if you can get em at half price with the same result, why would anyone buy the ones on amazon? that's not meant as sarcasm, I really want to understand the difference, I don't mind paying more, but not if I don't have to!

Could I make this work in an apartment if there were existing coax runs to the rooms, but the fiber modem is in a utility closet. I don't believe there is a coax drop in there, so I'd be running an ethernet jumper from Router to one then a coax patch cable from the "one" to a wall jack...and that would allow the apartment's internal coax routing between rooms to carry signal to wherever I had #2 unit....Is that the gist of it? A Powerline might be the same without the patch...

For $200, I'd much rather save time not pulling ethernet and use something like MOCA that works well. Ethernet isn't free - you'll have to pay for that ethernet cable, the crimping hardware, plus the time it takes you to do the work, and maybe you make mistakes that end up costing more to repair.

If you already got coax, $200 over 6 years of electrical usage, while getting very good throughput and putting in ZERO WORK, is super reasonable. Time is money.

Quote from Dannacus :
Does anyone know the range of a device like this? How long can you extend 2.5 gig ethernet over coax RG6?

I use a different brand adapter, but it should be similar. I have 20+ year old coax around my house and use a network of 3 moca adapters without issue, including through splitters and couplers. The wires are external, traveling all the way around my house, with the longest run being probably nearing 100ft. Iperf shows 900+mbps (i dont have 2.5gbps gear other than these adapters) with no noticible packet loss.

The frontier ones are basically surplus from the cable ISP...they dont have an official warranty as far as I could find. Similar equipment from other ISPs have also been cheap...sometimes they lock down functions in the UI, but the hardware is the same. I had Actiontec WCB3000N which were previously from an ISP...worked just fine.

I am a huge fan of MoCA, but there are caveats:
- You have to make sure that nothing else is on the coax using the same spectrum...mainly an issue with satellite TV.
- The whole network shares one large pipe, similar to an ethernet hub or one wifi AP. With switched ethernet, each point-to-point gets its own full pipe. Basically, dont run huge file transfers between 3+ machines simultaneously!
- If you mix MoCA, despite what the white papers say, your network will likely slow down to the slowest link. I had a mix of MoCA 1.1 and 2.0 bonded, and I experimented with taking the 1.1 off and on, and the network speeds (iperf) would go from the full gigabit to the 170-ish Mbps of 1.1.
- older MoCA, like most wifi, isnt full-duplex. MoCA 2.5 IS full-duplex, however.
- Some MoCA adapters only have gigabit ethernet (not this one), so despite the backbone being much faster, you will be limited to gigabit at each node.
- You are limited to 16 nodes...not a major issue for most normal people, but food for thought.
- You need a coax splitter which works above the 1ghz spectrum to get the full speeds of 2.5. It isnt expensive, but just check.
- if youre using cable internet, you will need a Poe filter where the signal leaves the house so that everyone else in your neighborhood cant see your stuff. If you are using fiber, this isnt an issue.

The good news is that you can use RG6 or RG59...MoCA is quite tolerant of really crappy coax cable.
Many ISPs have MoCA built into their modems or ONTs, so you might only have to buy adapters for each node/PC/wifi hotspot

The most important part is that you will get network speeds indistinguishable from ethernet with MoCA...for smaller networks, this could be even faster than ethernet since 2.5/10g switches are still really expensive.

FYI, you can get the frontier communications branded 2.5 moca's for a pair for like 80 or less all day long on ebay. They work great ime.

I pay 3 times (and rising) the average $/Kwh. That being said, I would gladly install MOCA adapters if they are more reliable that Powerline adapters (which I'm sure they are), but I would also consider paying someone to run Ethernet cable into a couple rooms.

There is also adapters called deca. Deca and mocause different frequencies. They are meant with either using cable or satellite. If you use neither you can get some deca adapters for pretty cheap.

Does this cause any issues with roaming if you have multiple APs throughout the house? Wondering if the increase in latency is significant enough to cause any issues.

Consumer grade DECA never went beyond 100Mbps and was made obsolete when DTV receivers gained the ability communicate natively over coax; no DECA adapter required. Cheap but not fast.

GigE DECA is available but not cheaper/faster than the Frontier 2.5 MOCA adapters.

Getting Frontier, will they supply these or do I have to request them for a charge? Used to the modem rental scam, so hard to know what you'll get charged for. TIA for a reply. 👍
