![]() If your MoCA adapters don't come with coax splitters and you are connecting multiple cables, you'll need MoCA compatible coax splitters that support up to 1625 MHz.If your MoCA adapters don't come with coax cables, you'll need short RG-6 coax cables to connect each adapter to the wall.If your MoCA adapters don't come with Ethernet cables, you'll need Cat 6 or Cat 6a Ethernet cables for each adapter.MoCA adapters may come with short Ethernet cables, coax cables, and a coax splitter. If your router does not support MoCA, or you want to create a separate coax network for MoCA, then you'll need at least two MoCA adapters.Īctiontec ECB7250 Bonded MoCA 2.5 Network Adapter.If you have a router that supports MoCA already, you need a minimum of one additional MoCA adapter.Setting up a MoCA Home network is quite simple, as it often requires no software configuration. Likely it will cause issues with all three.What You Need to Set Up a Home MoCA Network This may either reduce the MoCA connection's bandwidth or will cause interference on the DOCSIS internet connection and/or cable TV. The problem this introduces for your proposed setup is that MoCA requires similar communication bands that DOCSIS uses, and your Cable TV will be sitting using. This means you must have that cable modem attached to the same connection as the TVs in your house. If you can supply the model number and manufacturer of the modem I can confirm this. The cable modem is getting it's upstream connection via DOCSIS as (to my knowledge) Comcast does not use MoCA for their WAN. That's a discussion best held in another question, but there are many examples and tutorials available online on how to do such a setup. If you cannot, then you might look into running Ethernet alongside your existing coaxial cable connections. If you can, good! My speculation on DOCSIS vs MoCA is wrong. What you can do to test this with the equipment you already have is set it up in the above configuration and see if that PC in the other room can reliably connect to the internet. |- Coax|MOCA|Ethernet - |Īnd in the other room, of course: WALL - Coax|MOCA|Ethernet - Device The network diagram will then be: WALL - Splitter - Coax|MODEM|Ethernet - WAN| |LAN1 - PC Modern 'integrated' WiFi routers have this routing capability built-in, so you can use the WiFi router you already have, or the wired-only router you already have for this purpose. This means you must use a router to expand the number of devices that can use that connection, as otherwise Comcast will only deliver a single network address to the first device you connect. It sounds like the Comcast supplied cable modem does not have a built-in network switch and only has a single Ethernet port on it. Ultimately, consider it a long Ethernet cable. The Ethernet signal is simply encapsulated for MoCA and sent through the coaxial connection, and decapsulated on the other end back to Ethernet. The adapter you purchased is a 'bridge' type adapter, in which case the concept is that of a fancy media converter. Should this work? Is the MoCA adaptor smart enough to just route LAN traffic? Am I likely to run into trouble with Comcast expecting the router to have a certain MAC address, or any of that sort of nonsense? If I'd be better off just running 50' of cat5 under the floorboards, I'd rather find that out before I go any farther down the MoCA route. On the other hand, I might have a wired router at the bottom of a box somewhere, in which case this seems like it might work, in theory: wall #1 -coax-> splitter -coax-> cable modem PC However, that's another $80-$100 down the drain plus it seems stupid. Now, there is a third cable outlet elsewhere in the house, so theoretically we could get a third MoCA adaptor and plug both it and the cable modem into that outlet, while using MoCA adaptor #1 just to hook up the PC. However, before getting this far, we realized there was a problem: neither the cable modem nor MoCA adaptor #1 have a free Ethernet port, so there's no place to plug in the wired PC. We got an Actiontec ECB2500CK01 two-adaptor MoCA kit and, following the instructions and some internet forum advice, set it up as follows: wall #1 -coax-> splitter -coax-> cable modem MoCA adaptor #2 -cat5-> wifi router We do have another cable outlet at that end, though, so we're contemplating using MoCA to run ethernet over the cable setup. Unfortunately, though, the wifi signal doesn't reach to the back of the house. (The modem is an Arris TM822G DOCSIS 3.0 model that also provides phone service). We have these all set up in the same room and it basically works: wall -coax-> cable modem -cat5-> (WAN) wifi router (LAN) -cat5-> PC We have Comcast cable internet, and we want to connect two devices: one WiFi router, and one PC via a wired connection. ![]()
