    Actually the amp is inside of the main splitter. It is in the basement right before a lines go into the tivo, cable modem and small cablebox (PiP use)

    Basically the lines are as follows:
    -Main splitter (outside)
    -One line goes to the basement which feeds the amp, then after the amp it goes to the components mentioned above
    -Second line goes to the attic, where there is a splitter to go to the different bedrooms, where the tivo mini is.

    Hope that gives you a little perspective of my setup.

    I did notice that the cable coming from the wall into the Mini was not like the others (thinner more flimsy), so will switch that out with something else I have.

    Thanks again!

    "Hope that gives you a little perspective of my setup."
    Yes, but we need a little more....are there several out ports on your amplifier or just one?

    There are definitely more than one. Probably at least 4 outputs to one input. I think this is the amp that is installed (my wife sent me a pic and it looks like this one):

    All cable TV RF video lines are at 75 ohms, whether they're using RG59 or RG6. The difference between them is the bandwidth/frequencies they can carry, not the impedance rating. Old rg59 was good enough for the old analog systems but the newer digital ones needed more bandwidth so they went to RG6 in the home. They're both rated at 75 ohms impedance.

    The 75 ohm impedance issue has gone a bit astray, from this original comment by fcfc2...

    He was referring to terminating any unused coax ports with the little screw-on F-type terminator caps, to reduce noise insertion.

    You could also disconnect any unused lines from your cable plant and terminate the now-open ports -- or downsize your splitters to just the number of ports needed, to improve signal strength.

    Thanks all! just finished bypassing the amp with the main line. I setup the MoCA network and my TiVo Mini found the network and is now setting up!!
    Thanks so much for the help!

    I ordered the POE filter from Amazon, should be here by Saturday. My only question about that is how vulnerable is my home network until I get the filter?

    Thanks again!

    I understood that, but I wanted to clear up some misconceptions he had to make sure if he saw any rg59 instead of rg6 then it should be replaced as it could also cause issues with moca.

    Hi again,
    Glad you got it sorted out, if you discover that you need amplification a single port bidirectional standard amp can be used if place on the main line and a POE filter and splitter follow, otherwise there are MoCA rated amplifiers.
    A word of caution though, there are a couple guys selling Commscope multiport amps on Ebay and they claim they are MoCA compatible for cheap, but they are not in fact MoCA units and will block or severely degrade the MoCA signal. The problem is compounded because the manufacturer, Commscope, lists 2 different items with exactly the same model number one is MoCA friendly and has a small yellow label which says MoCA on it. The other is a MoCA killer, you have that one.
    PS. You are probably safe with the MoCA network until your filter arrives, but it is good to use one anyway as it will give your MoCA signal a slight boost.

    Thanks for the info. Right now the signal (not going through the amp) looks great and the mini seems to be working perfectly. I think comcast just added the amp "just because" they are told to instead of using multiple splitters...I will be moving to FIOS in the fall so may be back on this thread asking more questions. But for now, I am good to go!

    Thanks again!

    Confused and looking for clarification please.

    I have fios so my router is moca ready I believe.
    My setup is this...
    A tan cable (that looks like a thick phone cable) comes out of the floor and goes into a little white box.
    That box has a Ethernet cable that connects to the router.
    The router also has a coax cable connected to it that comes out of the floor too

    If I buy a roamio basic and mini, do I need a moca adapter at the router and/or the tivo/mini?
    Do I need a Ethernet connection to the tivo/mini? (There is no way I can run Ethernet to the tivo)

    OR

    Can I just hook the tivo/mini to coax and be done with it?

    Let's assume that's the case...

    ... especially since your connections seem to indicate it is so.

    Assuming your FiOS router has created your MoCA network, you will only need to buy a single MoCA adapter *IF* you cannot run Ethernet to wherever your new Roamio basic will be installed. The base Roamio, unlike the Plus, Pro and Mini, has NO built-in MoCA capabilities, and so must rely on a separate MoCA adapter if a direct Ethernet connection is not available.

    edit: See TiVo's support page detailing how to connect to your home network, specifically under Option 2: Join an existing MoCA network :: TiVo Roamio (be sure to review the associated image)

    Hi, if you cannot get ethernet to your Roamio Basic, you will have to purchase one MoCA adapter and connect it near by your Roamio. Most would just use a 2 way splitter, one leg to Roamio and one to the adapter. Then make your ethernet connection from the adapter to your Roamio and you should be good if you are using one of Verizon's routers which have MoCA builtin. If you don't use Verizon's router then you will need a 2nd MoCA adapter to connect to your router. The mini has it's own built in.

    Can one TiVo Mini gracefully coexist with two Roamios on the same MoCA network and get to the content of both receivers intuitively (meaning, does it have high WAF - wife acceptance factor)?

    With the great OTA deal, I am considering throwing a second receiver in the mix with my current Roamio/Mini setup... Are all three able to co-exist with high WAF?

    It only takes a few seconds to switch hosts for the mini. But there are several button presses/menu changes involved.

    I don't think it's a big deal but it might be for someone else.

    But the only reason to switch hosts is to watch live tv on the mini. You can see and play the recordings from the host TiVo and other TiVos on the network (with the same Media Access Key) without switching hosts.

    So let me get this straight... If I have two Roamios, the mini aggregates the recorded content from both devices and shows them all to me under "My Shows"?

    And the only reason I would want to switch hosts is if I care about whether I am grabbing a tuner from one machine or the other (which I am not sure I ever care about)...

    Do I have that right?

    The "Host" Roamio's programs will be shown in My Shows by default.

    The other Roamio will appear at the bottom of My Shows (or under 'Devices', depending on whether or not you're using the Left column view.) Select it, and you'll see what's on that box.

    My step-daughter just moved into a new home in Hiram, GA, which she is renting. I got her a TiVo Roamio Basic (TCD846500) as a housewarming gift and set it up for her in tandem with her Comcast X1. (She has the HD Preferred Xf Bundle package with a TEC tc8305c gateway and the Pace PX013ANM (X1) DVR.) We got the CableCARD provisioned and paired successfully and everything seems to be operating correctly. If she (and her family) decide that they like it, they will presumably turn in their Comcast DVR and HD STB.

    I connected the Roamio to the tc8305c via ethernet cat5 and noticed that the X1 was only wired via coax. (I don't believe that she has an active MoCA network through the tc8305c so the X1 must be communicating wirelessly.) If she wants to get a TiVo Mini for one of the bedrooms (where there is no ethernet connection available), then I believe we could swap out the X1 for an XB3 (model no. DPS3939, TC8706c, DPC3941t, or TC8717) which I understand has a built-in MoCA bridge. Once the MoCA networking is enabled in the Comcast gateway, and with the Roamio connected to the gateway via ethernet, my understanding is that the TiVo Mini client (which is MoCA-enabled) should be able to communicate with the Roamio (which itself is not MoCA-enabled) over MoCA.


    Did I get this right? I have no personal experience with MoCA, but I believe I understand the basics.


    How difficult is it to set up the MoCA network on the Comcast XB3 gateway? Should she plan to call in to Comcast technical assistance to accomplish it or is it something she can easily do herself?


    Any advice/assistance will be greatly appreciated.

    Completely, theoretically. And at least this post indicates it should work. (edit: another post indicating success enabling MoCA on XB2/3 gateways)

    However, I haven't tested this and can't say whether Comcast allows the customer to enable that XB3 feature, or whether the XB3's MoCA network would cause a problem for the MoCA-enabled X1 DVR on the same coax plant. It *should* work, especially if the X1 DVR is removed from the configuration, since the MoCA 2.0 certification indicates compatibility w/ the Mini.

    It should be relatively easy, just a tweak of a setting on the gateway -- with improved chances for overall success since her home is already MoCA-ready, given the prior X1 DVR install.

    She should be able to do/test it herself, so long as she can replace the gateway and then log in to it to modify the MoCA setting.

    I'd appreciate any help! Just got a new roamio basic and TiVo mini to replace an older hd box. Really looking forward to multi room capability but can't get it set up.

    I have a fios router in upstairs spare room (not close to roamio setup in lr.) Hooked up mini in another upstairs bedroom. Mini located moca network, connected to TiVo service, and updated. I then set up the roamio downstairs with a moca bridge (from TiVo). Set it up per diagram: coax from wall to adapter, coax out from adapter to roamio, and Ethernet connected between adapter and roamio.

    After that set up, there is no option on the roamio to connect to a moca network. There is only wireless or Ethernet. If I try to connect via Ethernet it fail. I'm unable to connect to the TiVo service and the mini upstairs cannot connect to the roamio for content.

    Any ideas?

    Setting it to ethernet is correct. The base Roamio doesn't have any moca options. As far as it knows, it's connected by ethernet (which it technically is).

    It sounds like the coax line to the Mini is working fine, so there's something questionable about the line going to the Roamio. The problem is either the moca adapter, a wonky splitter (most likely), or an amp if you have one on the line somewhere.

    The first thing I would try is replace the splitter(s) leading to the Roamio's line. Use one rated for at least 1GHz (1000 MHz).
