Ha ha…that would be a definite maybe 
Great article. Looking for a more cost effective solution to do this. There seems to be some.

Interesting! It’s a concept I heard about recently as a friend mentioned was having some repairs done to his CCTV system. Concerned that the base unit would struggle to connect to his WIFI and with no available ethernet, the engineer used old coaxial cables from redundant BSB TV he had in his loft area and routed around the house. It worked a treat!
Definitely a work-around that many people may not be aware of and could be pretty damn useful. Good find @Miki and now we are all digging around the house checking out our old cables and sockets

Hi Miki, I am running a complete MoCA system throughout my house up here in Canada. I became a cord cutter the same time that Troy come online and have not seen cable TV since that time. I first learned of this down in the States about 2 years ago when I visited a friend who had just rewired his whole 1800’s heritage house using old coxial cable that had been installed in the house over the years. It worked fabulously and consequently when I returned home to Canada I brought 6 MoCA converter boxes back with me and hooked up my house with a system (part MoCA and part wifi) for all my streaming needs. works great and I only pay for 150MB internet per month.
Great system!!!

I have a question about this. I have read on Amazon and I did find a more cost effective solution that you must be hooked up to the router for this to work. My situation is the main cable comes into the house and splits to different rooms / runs outside… I do still have cable that provides internet, phone and tv. I’ve recently moved the modem router beside my tv so most of my devices will have connection and wifi very close. The pc I had hooked up before via Lan then used Wifi through a pod. I have three. I then connected it to the RJ45 port right on the pod and it works even better. The pod is upstairs. Running through the coax would be like a powerline connection. The question is would it actually feed that coax connection since they are all hooked up. I am thinking not as the modem goes to everything via HDMI or wifi. Thoughts? I don’t think the signal will come back, I only want internet on my computer.

Sounds like you have a triple play for your service…so you should have an ISP provided gateway (modem/router combo) with 2 phone line ports & 4 ethernet ports…correct or no? I’m not exactly sure what you’re asking so I just want to make sure what equipment you are using to get a feel for your setup. You also have some wifi etxtenders that you can hardwire from your gateway?

My service is Rogers with Rogers ignite. Cable comes into Rogers provided router/modem. There are ethernet ports* No longer used and phone jacks. Absolutely everything is via wifi. The Tv box has no physical connection to the box. The tv is HDMI to that box. I have another coax connection in a computer room where this device used to be connected but I moved it to have better proximity to all our wifi devices. My question was and I don’t really think it’s possible , If I was to connect to the spare connector (They are all connected where the main cable comes into the house) if I would be able to get the ethernet via the coax cable using that adapter. I don’t really see it but had to ask.
** Yes I have 3 wifi extenders or as they call them pod that talk to each other. It’s a mesh system but not all that great. I do have one computer plugged in to it’s RJ45 port and connected via wifi (Either or) the ethernet is faster to the computer even though the pod gets its signal via wifi. This is just to answer the rest of your question. I would disconnect from it and use coax if that was actually possible just like a powerline adapter sort of.
I guess I’m not being clear. In the picture above, the service coming from the internet to the modem isn’t connected to the home coax system. In most homes with cable internet, it’s the same wiring and can’t be disconnected as shown in the picture. Now I know cable TV signals and internet signals can share the same cable as their frequencies are very different and don’t interfere with each other but can internet signals and ethernet signals share the same cables? Has anyone actually done this?

It’s a standard regular cable service from their box to the splitter outside my house. Each cable run inside going to different rooms. Yes, my internet and tv run over it and since the phone is VOIP it does as well. The modem is plugged into a wall outlet that is a run to the outside box. 100% standard just as POTS, telephone wire with different runs going to different rooms, outlets. That being said, I am sure I can’t connect up to a coax outlet in a room as the signal from the modem/router is not going to go backwards to the splitter box as those are inputs for signal. When I first saw the article, I started to think and wonder if I could plug into my coax outlet in another room because they are all connected to the same outdoor splitter box and the more I thought of it, the more I realized that there can be no possible way unless the cable run was a direct output of the modem if that makes sense. My guess about DSL or Cable internet from the ISP could probably share the same cable as yes, the frequencies are totally different just as an ethernet signal from a modem/router runs flawlessly in the electrical system of a home using power line adapters to bypass long or difficult signals of wifi. They have no problem and this technology dates back to the 80’s. Power line adapters.

Reading all the comments, it seems to me that the biggest challenges are 1. finding a coax wall outlet near my modem, then 2. hoping the coax in that outlet connects directly to coax in a remote point in my house where I want to hardwire a tv or Firestick. Is that correct?
If I cannot find that direct link, the MoCA technology won’t work, even if there is a coax wall outlet near the tv?
I’m currently using ethernet over powerline adapters. The house/wiring is 40 years old. It does not require direct connections. However, by the time the signal gets to the far end of the house, I may get speeds below 15 MPS.
Coax sounds like a better alternative, but only if there is a direct cable run?
First and foremost, you put a coaxial cable with one end changed to a LAN connecting adapter directly into your Router. The other end, still with its original coaxial connection should go directly into the first available coaxial wall socket. Wherever that socket terminates, ie in another room, you locate that socket, coaxial cable direct from there with the LAN adapter connected at the end that will go directly into your device LAN Port.
Keep in mind that if that coaxial cable splits via extensions into other rooms, you may loose or reduce the data. Might even lose the connection to all but one device, so there may have to be some experimentation to see how effective this system is in reality. My thinking is that a direct, single link/cable as described above will work as a stable connection. Any splitters or extensions in the coaxial cable may well interfere, but only way to find out is give it a try. And because we all may have a different set-up in our original coaxial cable configuration, we may all need some level of trial and error experimentation to see what, if any configuration works for you.
You can’t backfeed into the computer room cable outlet to get service to it…but if you have another open cable outlet close to your modem/router so you can “plug” an adapter into it…then yes…you can get the computer room outlet activated. If you do have that other cable outlet…I’d be happy to explain how. Old “trick of the trade” in the cable biz 
@peterrsa123 From reading your post…this may a viable option for you also.

Thank you but I don’t. It’s a typical home with an output coax connector and the modem router has one input. If it had another output and I had another feed I could do it. My system works fine now but I could for the fun of it, use the Ethernet out to my older Cisco Powerline adapter then plug into the other end in my computer room. The lan to coax just seemed like an interesting idea.
Copy that…it is a good idea…if you have outlets everywhere in the home. I don’t need it either, but it would be fun to play with.
Thank you. Good news is Amazon will take back the hardware if it doesn’t work. I’ll give it a try and report back.

To answer your question…
It won’t directly…but all you need to do is locate the splitter that feeds all of your cable outlets throughout your house. Unless it has been “Harry homeowner-ed” in some way, they all will end (or begin) at a splitter/s where the ISP service drop connects to your house…or from a primary cable that runs into your house from that service drop, & is then split to all the rooms. In case you’re not aware…the service drop will be located outside near your electric meter on the utility side of your home (so it can be properly bonded/grounded to your electrical system)…there may be a house box attached to your home. From wherever the splitter is located, you can combine/attach all available rooms to your MoCA network. You might need a coax pocket toner to trace the wiring locations…a MoCA compliant splitter…or if just setting up one room, a cable barrel to connect 2 cables. All can be found on Amazon by typing in those search words. If you try this I look forward to the results
Miki! You rock! 5,000sq ft home with miles of cable everywhere and I’m installing wifi extenders? DUH! I’m going to be busy this weekend! Outstanding catch! Who knew! Thanks!

Found splitter feed in the attic. Nees to be upgraded to the MOCA frequencies. Attic temperature is >100 degrees (Florida house). I’ll wait for cooler weather in January to connect MOCA, then report back.
I found an interim solution. I moved the Ehernet over Power adapter to diferent plugs, tested download speeds each time, and found one that gives >40mps consistently with VPN on That ssould be enough to fix the throughput issue to the problem Stick nicely for now.
Appreciate the help.

Copy that @peterrsa123 
Got a couple of questions: how many cable outlets are in your house…do they all feed down from that attic splitter…is there a 2 way splitter somewhere before the one in the attic? According to ISP best practices…the configuration for optimal signal is to isolate your internet line…so it would be like this: ISP service cable drop to house…that should connect to a ground block for bonding like I previously mentioned, then a short jumper cable to a 2 way splitter…one leg of that 2 way feeds your internet (only)…the other leg, presumably, feeds that attic splitter, then down to all your rooms. Also, a splitter in the attic denotes (to me) that your rooms were wall fished thru the top wall plates & you have outlets on interior walls in the rooms serviced…all cable on the inside, which would be excellent, as they would be in best shape in the walls rather than wrapped around your house outside in the FL sun. I ask all of this because you will need decent signal to do what you plan & I want to make sure your internet cable to your modem is only losing 3.5dB going thru a 2 way splitter…as opposed to 7dB going thru a 4 way. Also…it would be nice to know your modem up/downstream & noise (SNR) numbers before you build your MoCA.
@pangaeatech . The coax must have been installed when the house was built. Everything runs through walls to outlets. We have not used that coax network for 10 years now. OTA TV feeds from an outside antenna. Internet is ATT fiber to the main router. TV sets all have FireSticks connected by Ethernet over Power to the main router. WiFi to all rooms is via 3 bridges also connected over power lines to the router.
When i get back into the attic, plan is to disconnect any coax feeding in from the outside, and install a new MOCA splitter. I’ll then identify the coax cable running from near the router to the splitter, and connect it to the “in” port on the splitter. I’ll then identify the coax cable running from the attic to the far away room, and connect it to one of the “out” ports in the splitter. I won’t connect the other links because those rooms work fine.
Sound ok to you??
