Hello, I recently came across MoCA to use your house's existing coax cables as a pseudo ethernet port. I've been reading up on how exactly to get it all to work and I'm still lost on what I'll need and if it can even be done.
I'm looking at these MoCA adapters
Now, the part that is confusing me is all this talk about splitters and filters and what not. In my electrical box, I see a coax going into a weird looking splitter.
Do I have to remove those cables and buy a MoCA splitter? Do I have to add a MoCA filter to the black wire at the top? I also have a gray box on the outside of my house with wires. Should I check in there for anything?
Also, I'm pretty sure I have more than 3 rooms with working coax ports in them, why are there only 3 in the splitter?
If I get everything set up, should I run an adapter from my modem or should I enable MoCA on my modem (XB6) and use that as the "home base"?
One more thing. The adapters I linked comes with a splitter. I'm assuming that is so I can attach the adapter and modem to the same coax port that the modem is currently using, yes?
Sorry for all the questions, this is very intimidating and lots of information to sift through. I'm not comfortable just unhooking cables at the panel without worrying about messing anything up. Any advice would be appreciated!
P.S. Here is the splitter I'm looking at...https://www.amazon.ca/gp/product/B07RB61LR9/ref=ewc_pr_img_1?smid=A2N4NEZPB53SEZ&psc=1
@Leafs4ever this is actually pretty straight forward. Here’s what it would look like:
Incoming -> Cable -> MoCA -> MoCA -> cable --------------> splitter -> Modem
Cable Ground Point splitter -> cable -> adapter -> MoCA adapter
Block Of -> cable -> adapter
The question of whether or not to use the MoCA capabilities in the modem versus using a MoCA adapter is a good question. Unfortunately Comcast and Rogers hasn’t released any information regarding the MoCA capabilities of the modem, so no one knows if the data rates are capped or not. So, for example, if you were running gigabit service, would you actually see 900+ Mb/s via MoCA, or would it be reduced? I don’t think anyone can give you that answer, so, this is a trial and error answer. You could start by just using the modem’s MoCA capability. If it works as you expect, hurrah. If not, buy another adapter and high frequency splitter to install at the modems location.
Fwiw, the new 2.5 gigabit MoCA adapters use Maxlinear chipsets, same company that bought Intels modem division. I’ve seen posts for gocoax adapters which use the same chipset. In the presence of other MoCA controllers, the mixture of MoCA controller in an older Nextbox and the MoCA controller in the gocoax adapter, the two of them did not work together as the gocoax wanted to control the MoCa network and wouldn't take no for an answer. I don’t know if this same situation would exist today, if a mixture of the XB6 and the Actiontec ECB250K02 MoCA controllers would run into the same problems. Either it would work or it wouldn’t. You would probably know pretty quickly if it didn’t.
For the configuration as stated above, you already have the cable ground block, which is the ground block that holds the single incoming cable (black) and the three outgoing cables. That’s pretty unusual to see. Typically there is a single cable ground block installed, which has one cable coming in, and one going out. Grounding the three cables is overkill, but, you still need that ground block.
Leave the incoming black cable connected to that ground block. After the ground block, you would disconnect the three cables and connect an MoCA Point of Entry Filter to the center port. That would connect to a MoCA splitter of sufficient size for your intended number of MoCA adapters. If you intend to have three rooms with MoCA running, then you need a MoCA splitter with three output ports. If you need only two rooms, then the MoCA splitter only needs two output ports. So, very simply, you size the MoCA splitter to match the number of adapters you intend to use including the modems’ location. Note that the larger the splitter, the greater the signal drop thru the splitter, so, signal levels could become a problem at the modem depending on where their at presently.
From those output ports of the MoCA splitter, you would connect the cables that run to the intended rooms. In the case of the modem location, if you don’t intend to buy an adapter for that location, then you don’t need the secondary splitter. You would simply keep the current modem connection and turn on the modem’s MoCA functionality.
In the other rooms, if there is nothing else to connect to the cable system, then it’s a matter of connecting a short cable to the rooms wallplate port, which then connects to the adapter.
For the modem’s location, in the event that you find that mixture of modem MoCA controller and adapter MoCA controllers don’t play well together, you will probably have to buy another adapter and a high frequency splitter.
As for the splitter that you pointed out that looks like a satellite splitter. My only question is whether or not it has the necessary internal port to internal port frequency response to support MoCA 2.0/2.5. It certainly has input port to output port and reverse frequency response, just not sure of the internal port to internal port frequency response.
Personal opinion, I’d buy a Holland Electronics MoCA splitter. Here’s the main site:
Here’s the MoCa splitter page:
Here’s the spec sheet that shows the various splitters:
The splitter that you linked to is a 6 way splitter. Do you intend to run MoCA to 6 rooms? If not, then you should be looking to minimize the splitter size in order to keep the signal loss thru the modem to a minimum. Fwiw, Rogers might supply you with a MoCA splitter such as one of the splitter shown on the bottom of this page:
If you run across a Rogers tech on your travels, ask him or her if you can scrounge a MoCA filter of the size that you require to do the job. It never hurts to ask the question as they say.
If you’re looking to run MoCA to 6 rooms, then I’d suggest an MoCA qualified amplifier such as the following. It comes in 5 port and 9 port configurations:
Those amplifiers have built in MoCA filters. Note that if you go this route, you might have to bring this in from the U.S. I wasn't able to find a Canadian source tonight.
Note that Rogers might supply you with a MoCA amplifier as seen on this page:
The techs should have the splitters in their van, the amplifier is a good question, don’t know, but, again, it never hurts to ask the question.
It might be worth a call to tech support to see if Rogers will supply you with the splitter or amp. Perhaps they will arrange for a tech visit at no cost??? I’d check on the no cost issue. It would make sense as signal levels come into play here.
Ok, that should do it. With all of the parts collected, it’s a matter of connecting one to another until its all set up and then firing it up. The only real question is whether or not the MoCa controllers in the adapters will play with the MoCA controller in the modem. This should work, but, be prepared to buy another adapter and a satellite splitter so that you have the required frequency response thru the splitter that you will require at the modem location. I’d also consider installing a MoCA Point of Entry filter on the modem to protect it from the MoCA network if you were going to use a separate adapter. You shouldn’t need it but, I’d consider adding it.
Alright, so I had a Rogers tech come in today to look at my set up. First thing, I sent a picture of the wrong hook up. Apparently that was an old hook up from Bell. Here is my current Rogers set up:
First picture is the cable from the outside and the second picture is the current Rogers set up. As you can see, it's just 1 cable to 1 cable.
Second, the tech did not know anything about MoCa so I didn't get any help from him in that regard. He brought a couple of splitters, but they were yellow labelled ones and he wasn't sure if they were even MoCa compatible. So, I need to find my own splitter I guess. He told me, I would just need to take those two cables apart and then attach the outside cable to the in port of the splitter and the other to the out port. He also said I could take the other 3 wires that are hooked up in the other splitter and move them to the new MoCa splitter. Is that all I would have to do for this than? Would I still need the POE filter? And if I do, the filter connects to the IN port and the outside cable goes into the filter right? Oh, and do I connect the splitter to that current silver splitter or remove that entirely? I do see that there is a copper wire attached to it. Also, when I unhook the cable wires and put them back together, does that mess up my internet settings or will it all boot up in the same way as if I just unplugged the modem and plugged it back in?
Here is a splitter I found and it says great for MoCa, but let me know if it'll work.
@Leafs4ever my apologies for not getting back to you sooner. Did the tech leave the splitters with you, and if so, do they happen to look like the Antronix splitters seen at the bottom of this Antronix product page:
If the splitters are the yellow faced Antronix splitters, then yes, they are MoCA II qualified.
From your picture, you have a single Rogers cable inbound into your home, connecting to a cable ground block. You still need that ground block so it should remain in place. Following that ground block, you would install a MoCA Point of Entry (POE) filter. Did the tech happen to leave on of those with you?
Following the ground block, you would connect the MoCA splitter.
You would then connect the house RG-6 cables to that splitter. With a MoCA qualified splitter, all that should remain is to connect the adapters to the coax cables and fire them up.
The splitter that you indicated might do, but, the question is, will that splitter support port to port communications, up to 1675 Mhz. MoCA qualified splitters allow port to port communications so that the MoCA adapters can communicate with each other. Other non-MoCA splitters might have a suitable frequency range from input to output and reverse, but, might isolate each port from one another. Due to the lack of specs for that splitter, its a guess as to whether it will support MoCA ops. You could buy one and try it out to see if it works. If you're able to drill down in to the adapters and see the signal levels, that would tell you if the splitter is suitable for MoCA ops.
Depending on what MoCA adapter you buy, its worth digging into the instructions so that you can log into the adapters, set them to run Delta band - Extended, which is the entire MoCA D Band, and also check the signal levels.
For a little reading on the subject, have a look at the following post from last week:
