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.

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.

Yea, my coax cables are stapled to the studs...'just pull some wire' works if you have a single level with an unfinished basement or attic. If you have a finished basement, two stories, and no clear shot to the attic, shit gets complicated real quick.

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. 👍
they are free of charge when i got mine, but they gave me fca251 which is
Quote from New_Guy :
Are these noticeably better than the Frontier FCA252 you can get on eBay for about $60 a pair (new)?
frontier gave me FCA251, they dont play well with asus moca. im sure FCA252 will work.

As another poster noted, DECA is capped at 100Mbps, which isn't going to cut it for most people.

Quote from Esente :
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.
At my house, Spectrum comes into a box on the outside wall and that cable connects to a splitter for all inside connected cables. I watched the installer reduce the size of the splitter from 8 to 4 after asking me how many rooms I wanted to have a signal. That means he left 4 rooms orphaned. So maybe check the outside box in case the individual rooms are disconnected from the splitter.

is this something that can be used for wired backhaul with mesh routers since I don't have ethernet wired throughout the house but have coax throughout?

100mbps is more than sufficient depending on the circumstances. But most people interested in ethernet over coax these days have internet service that's a lot faster then 100mbps. Not much sense paying $75 or whatever a month for fast internet and then use an adapter that neuters the bandwidth. Make a one time payment of $110 for these ASUS adapters, which should keep up with technology for years to come, and get the speed you're paying for. Or spend even less on something like the Frontier adapters.

Quote from 1-6 :
If you're ok with crawling into tight spaces, just pull new CAT6 cables. Adapters like these just become prone to problems and eat phantom power. Calculate what the energy use is over 6 years. (3w (estimate per device) * 2 devices * 24 hours * 365 days * 6 years) / energy cost per kWh

It could very well end up like $120 extra for 6 years for the life of your setup. Not a whole lot but still.
Go one more step to save even more money. Cancel Internet service, no running wires, no phantom power consumption. Easy money saved, lot more time for tackling home to dolist.

Yes. One of the best use case for these adapters.

Setting this up for the first time; could use some help with plan validation below.

There is no power outlet close by, and my outdoor TV box (see picture https://ibb.co/tLSF28H ) has six outlets total.

The plan is to link every room with the least amount of bandwidth loss possible, so the existing/not MoCa 2.5 compatible 2 way splitter will be replaced with this BAMF 6 Way Coaxial Cable Splitter. https://www.amazon.com/BAMF-6-Way...01KCY5MBU/


The ISP coax is connected to a white coax cable, as seen in the picture, to which a green ISP ground wire is connected. Can i bypass it or should it remain connected as is? The plan is to place this Moca filter https://www.amazon.com/Filter-MoC...00KO5KHSQ/ on the main ISP line that connects to the splitter as I am aware that I need one. Is this an appropriate approach for the TV box outside?

On the inside, the ISP coax cable lands in the LV and the plan is to install the Moca adapter there with a Cat5 connected to the router and one Moca adapter in every room thereafter. I also found another coax cable in the LV next to the ISP coax, but I'm not sure what this extra coax cable is for or if it will interfere with this configuration.

I've seen that my Motorola MB8600 is MoCA certified. Does it means it is already has a Moca adapter built-in and in this case i can use a splitter instead of adding another Moca adapter in front of it? Or does it means that the Motorola MB8600 is just compatible with MoCa?
