![]() For those who have perhaps been on the fence for some time, now is a reasonably good time to order as the Paypal $25 off $200 can be applied to these (PAYPAL2017). I already get complete coverage throughout my entire house with solid 50+ mbps via Wireless N 2.4 GHz for any/all of such devices which is more than enough for me. I couldn't care less about blazing fast throughput for my tablet, phone and the other few wireless devices I have. That said, for those who can make use of them, they are far superior to any consumer wireless implementation if what you need most is a bridge. Likely it will cause issues with all three.These don't ever seem to go on sale and likely won't for awhile as they are very "niche" in their application. 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. ![]()
