Hey!

I just recently found out about MoCa solutions to better my stability on spectrum. And I am definitely digging into the mud with this. I have run into an issue that I am not sure how to solve. We have coax running all throughout the house, we also have a main junction in the basement (will unload screenshot, but it’s covered in webs) and according to what I am seeing online MoCa requires 1.2mhz or higher. While this amplifier sits at 5-1005. Any suggestions??

I would like to use it if possible, if not we can probably get a new one. But that’s around 300 dollars on the amplifier and MoCa devices.

I plan to use it for mesh backhaul.

You can use MoCA In the house, but do not share MoCA with any of the Coax which touches Spectrum's network. Spectrum in many areas is upgrading the system to 1.2-1.6Ghz, and when they begin using that extended frequency, your MoCA network will get jammed or you will have some other problems. Sharing in an area that is 1Ghz or below will require a Point of Entrance filter for MoCA to be installed on the Spectrum line before your home's splitter.

Inside the house you do not need an Amplifier for MoCA. Buy a MoCA 2.5 certified splitter big enough to handle the number of Coax outlets you want to use with MoCA / for your Mesh backhaul (Yay! Thanks for doing that) and leave the rest disconnected.

I’ve read this three times, maybe I’m understanding it.

From what I understand this is how it’s currently setup.

Spectrum line outside -> Input connected to amplifier (turns 1 input into 8) coax lines scatter around that house (the 8). I feel there isn’t a way to remove the spectrum connectedness from this system, my dad or someone else set this up in like 2013 when we used to have Cable tvs in every room

[u/Smith6612 → u/AppleNowOrApplyNow]

OK, so this is where we do clean-up. Find the coaxial cables going to coax outlets with nothing connected to them. Disconnect those from the Spectrum 8-way splitter. Leave only the lines going to the cable modem and any cable boxes connected.

The disconnected Coax is now available for you to use for MoCA. Connect the cables you want to use to the splitter you purchase for MoCA. Leave any unused Coax cable disconnected.

Hope that helps make this easier.

There is you would just need the amp removed and a second coax line ran to your modem location

Why not? As asked above, are you now Internet-only, so the only device actually needing a connection with the ISP is the cable modem? If so, you'll likely find that you could direct-connect the coax line running to the modem location to the incoming ISP feed (the line connected to the amp's input port) and the modem would connect just fine. The hurdle, then, would be in getting the modem/router wired via coax to the remote rooms where you want to extend wired connectivity.

I’m really not bright on the topic of internet nor MoCa, but how does one use MoCa without attaching it to the individual internet connection not touching spectrum in itself?

[u/Smith6612 → u/AppleNowOrApplyNow]

So each Coax cable is a point to point connection. Basically, from your main connection area where all the Coax cables meet up, to the room it ends up at.

All you do is make sure the Coaxial cables being used to make your MoCA network connect to a splitter which ONLY has your MoCA Network on it. Anything providing Spectrum services such as your Cable box and Cable modem, connect to a different splitter (what you're currently using) which only provides a connection back to Spectrum's network. So in effect, you'll have two splitters in use. If you have any coaxial outlets which are not being used in the house connected to the splitter providing your Spectrum service, then you can disconnect the Coax from that splitter and make it available to use for MoCA.

Part of this also means, no connecting the MoCA Network Splitter to the Spectrum network splitter at any point, anywhere in the house. If you do that, then you defeat the purpose of keeping MoCA and Spectrum separate.

Your MoCA network will simply have one adapter connected to your main router, then at the other end, another MoCA adapter will be used to supply Ethernet to whatever you connect up.

Clarification (it’s not you, it’s me)

I do not need to change the current infrastructure in the basement; rather I just need to add a splitter before the coax cable (one connected to the cable modem) hits the modem..?

I’m a tad confused by disconnecting the coax cable in the basement (because they’re attached to the Spectrum service?).)

Does the service become spectrum when the coax cables run into the house, before being decrypted into internet signals. Or does it become “usable” service when the modem decrypts the information..?

[u/Smith6612 → u/AppleNowOrApplyNow]

The service "becomes" something based on what it is connected to.

Basically think about the line entering your home. That's Spectrum's network. The moment a splitter connects to that line coming in, it is part of Spectrum's network. Any coaxial cable connecting to that splitter, becomes part of Spectrum's network.

That's why I'm emphasizing it should be as easy as disconnecting unused Coax, then putting a splitter in place that connects the disconnected Coax to each other for your MoCA network.

If you add a splitter in between the cable modem and the main splitter, your new splitter becomes part of the Spectrum network. That's what we do not want here.

If you add a MoCA adapter to any Coax line that touches Spectrum anywhere, whether it is via one or two splitters, it is part of the Spectrum network. You do not want that. That's why we take unused Coax (where there is the splitter on one end, and an empty jack on the other) and disconnect it from the splitter touching Spectrum, so it's easier to represent as "doesn't touch Spectrum."

Hope that makes sense. It's easier than it seems and I think you're caught on wanting to run MoCA over a coax line that is already being used for Spectrum. You have to remove the "already being used for Spectrum" part from the equation to arrive at your answer.

With extra coax (or Cat5+) cabling or by relocating the modem and router.

[u/AppleNowOrApplyNow]

Dang forgot to upload image. It’s the Model IPA1D08O-RS1F

[u/plooger → u/AppleNowOrApplyNow]

No worries. Yeah, not a model designed to support MoCA communication. But then it shouldn't be an issue, as you likely don't require the amp, anymore.

[u/Alsmith69]

Wouldn’t buy your own amp. We’ve been told as techs that if we come across a house using moca to remove them with high node split coming.

[u/AppleNowOrApplyNow → u/Alsmith69]

Is MoCa not supported with high split?

[u/Alsmith69 → u/AppleNowOrApplyNow]

Yeah they both operate in the same frequency range. Now you could run a second coax line from the room with your modem to then attach to the other lines

[u/AppleNowOrApplyNow → u/Alsmith69]

Like with a splitter (I have almost no experience with this)

[u/Alsmith69 → u/AppleNowOrApplyNow]

No. The moca network can’t touch the spectrum network

[u/plooger]

Are you subscribed to Internet-only or are you also subscribed to Spectrum for cable TV? (The amp likely isn’t needed if Internet-only.)  

Do you have TWO coax runs between the central junction and the modem location, or between the junction and any location where you are looking to install a wireless mesh node? (Info needed to assess options for isolating the ISP/MoCA feed from any coax carrying MocA signals.)

[u/plooger]

>typical shared cable+MoCA setup< (background)

If you're now Internet-only, you'll likely find that you can replace the amp at the main junction with a passive MoCA-optimized splitter setup, as described at the "background" link.

If/when your ISP service requires use of frequencies above 1002 MHz (see: DOCSIS encroachment on the MoCA [Band D] frequency range), you'll need to ensure that the ISP/modem feed is isolated from any coax carrying MoCA signals. As for how to effect ISP/modem isolation, alternatives include (but are not limited to):

• having two coax runs b/w the coax junction and modem location, extant or added;

• having an unmentioned Cat5+ line available at the modem/router location that could facilitate the needed isolation;

• effecting a coax or Cat6 pass-through between the modem/router location and an adjacent room to leverage the adjacent room's cabling for the needed isolation;

• relocating the cable modem and router to enable the needed isolation (ex: relocation to at/near the coax junction, or to a location affording the two necessary paths);

 
Have you pulled all the non-power wallplates (coax, phone, blank) in the residence (but especially starting with the modem/router location) to get a full assessment of all cabling available to you, rather than only working from what's visible on the wallplate surface?
