    Yes, but the problem is those 6 cables go somewhere and I don't know where. There's 6 cable points in the house and I only use 4. Plus, I didn't make it clear that the amp upstairs is a 4 port unit but only one input and output (plus the power inverter input). I don't even know why it's there or how it amplifies or affects (presumably) the signal to cable modem.

    I'm not an expert on cable TV :(. I was hoping if it's a simple issue of bandwidth just replace the stupid amp upstairs and forget about it.

    I can't quite follow your setup... If the amp can't pass MoCA, you need a new amp, or if it has enough power, have everything with MoCA on a splitter downstream of the amp.

    Modems can work fine through an amp, my parents have one that's been running that way for years.

    I'm fine with getting a new amp. Just wondered if it was definitely the 50-900MHz causing the issue. I think it is. I will buy a new one and post results.

    There's a decent chance the 900 MHz limit is blocking the moca, yeah. A bi-directional 1000+ MHz unit would be better.

    I fixed the problem (well, the cable guy did).

    There were two amps, a booster in the room and something which powered another amp in the outside wall cavity where the cables came into the house. When I removed the in-room amp, the power was cut to the second, making it act like a choke and cutting off all RF into the house.

    We simplified the cabling in the house and routing, and put a new power supply back to the in wall amp, and all works again.

    My situation for some reason had got so complicated (and this was probably done 6-8 years ago) that it took Kevin the cable guy (10/10 for knowledge and willingness to help - thanks Cox!) to sort it out.

    Now my XL4 and Mini are working great. Next is to see if I can get my XBMC PC next to the Mini. I think I need some kind of Moca/Ethernet hub for that as I'll need Ethernet there.

    Good! That sounds a little scary though... an in-wall amp? How do you get to it if it breaks?

    You can just get a regular MoCA adapter and an ethernet switch.

    Also, you'd only need the switch if you want to plug in more than one Ethernet device.

    Which I might. These projects have a habit of growing :).

    Nice. Then grab one off Amazon or Newegg for $30. Amazing how cheap they are now.

    Help, please please. I'm good with IP and cat 6 but lost in the coax world. Please check my MOCA drawing for Roamio (4 turner without MOCA bridge) and Mini. Is it right?

    Two questions:
    1. Would it be better to use a four-way splitter to allow the cable modem to be directly connected (so that traffic between the LAN and Internet didn't have to go through the MOCA bridge). I'm using the Actiontec bridge. Is it a potential network throttle point if placed upstream from the cable modem and my Router?
    2. The 130' run to the Mini: The RG6 is good, but it has one barrel connector outside. Is this likely to work OK or will I probably need an amplifier?

    Thanks

    I might be wrong, but I'm pretty sure you need a MoCA adapter directly connected to (at least) one of the Roamio Basics, as it doesn't have one built in like the Roamio Plus & Pro.

    As long as the barrel connector is rated for at least 1000 MHz, it should be fine. *IF* there's a signal problem, make sure the amp is also rated for bi-directional 1000Mhz (at least). But that's likely unnecessary since moca has a 300 foot range.

    Is the moca network for the Mini only? (the diagram labels two 4-tuner Roamios so I'm assuming the 130 foot run is actually a Mini and was just mislabeled.)

    But as shown, it should work fine. If the cable modem service interfered with by the moca adapter, inserting another POE between them should resolve it.

    Interference with the Cable Modem is unlikely, and if there was a problem with the modem after setup, it would not be because of the MoCA frequencies. The Coax Out port on Actiontec adapters does not pass on the MoCA signal, so the Cable Modem is already protected from the additional MoCA frequencies.

    Confused ! I have a Roamio Plus and a mini in the bedroom. I have them both set up but they don't see each other over moca. I have to access the internet via my Netgear wireless router and the RP works fine. When I choose 'use this device for moca' so I can use the mini, it disconnects from wireless. Everything I'm reading says they should talk to each other over coax (without ethernet ?) but they don't (error C33). Do I need a moca adapter at the RP ? I had to take the modem and router into the bedroom to get the mini loaded (included the upgrade) via ethernet but now it won't connect with the RP.
    heeelllp!!

    In order for the Roamio Plus to create a MoCA network, you must be able to connect it directly to your router via Ethernet. If that's not possible due to being in different rooms, you'll need to install a MoCA adapter at your router.

    So, you mean it has to remain hard wired ? Even after the network is 'created' ?

    Yes. I think you might be misunderstanding how the bridging function works.

    For the RP to be the MoCA "head end" and create a MoCA network it must be connected to wired ethernet, not wifi.

    If you can't easily do this then buy a MoCA adapter, connect it via ethernet at the router and have the RP and Mini both be MoCA clients from that device (the RP will no longer be connected to wifi).

    Yes. The Roamio must remain hard wired if you're using it to create the MoCA network for the Mini.

    The Roamio Plus can't bridge Wifi to MoCA? That seems like a really stupid design...
