MoCA error on setup

    I'm getting the same C33 MoCA error on my mini, it's driving me mad. I have FiOS and an established MoCA network in the house (I can whip up a block diagram if it'll help).

    I have an Actiontec MoCA adapter that I can plug into the coax in the bedroom and that lights up right away and provides network connectivity to the mini (so I know the MoCA network is up and working on that cable drop), but if I hook the coax directly to the Mini and try and turn on MoCA is just sits for a bit and then gives me the C33 error.

    Any suggestions?

    Shoot - I was mistaken. I do indeed have the Tivo hooked up to the splitter that is connected to the wall (the other side if the splitter goes to the cable modem). So, regretfully, that avenue of investigation didn't pan out.

    Sorry about the confusion but I am still at the point where MoCA won't turn on (C33 error). Any other thoughts?

    You know, I'm starting to wonder if I have hit a bug on the Roamio. Here's why.

    So, I use the Turn on MoCA option. It takes about a minute and then gives me the C33 error. My assumption at that point is that MoCA is not enabled.

    At the bottom of that screen are three options - "Try again", "Change network (MoCA) settings" and "Use Ethernet instead". Given that I am trying to turn on MoCA, I receive an error and there's a "Try again" option, I assume MoCA is not turned.

    But here's the thing. If I chose "Change network (MoCA) settings, I get a new screen - at the top of which is the message "MoCA networking is currently enabled". Huh?!!!

    If I press the Back button from that screen, I get a screen that says "Currently using Ethernet to connect to the Internet".

    So, just very confused at this point.

    Are you sure the outlet with the Mini on is connected? Maybe hook a TV up to it and make sure it is getting a signal. Is there a distribution amplifier on the coax? If so, you need to ensure it is positioned so that the Moca signal does not need to go through it. Also check the main splitter at the cable entry and make sure it is not powered and is rated up to at least 1GHz.

    Does anyone know what frequencies the discrete frequencies in the MoCA settings correspond to (e.g., 15, 17, 19, etc...). I feel like the Tivo just isn't seeing the MoCA network because the "Auto" isn't finding the existing network... I was able to dig into the FiOS router and the internal MoCA network was initially set to 1150 MHz and I was able to change it to 1350 MHz, but that didn't help. If I can figure out the frequency to channel conversion, I can eliminate that as a possible issue...

    OK, I've solved my issue.

    The channels are:

    15: 1150 MHz
    17: 1200 MHz
    ...
    27: 1450 Mhz
    29: 1500 MHz

    I've found that both the NIM-100 I have in the house and the Tivo play nice and both can connect to the MoCA network using channel 25 (1400 MHz). I had to just log into my FiOS router and manually step through each frequency until I found one that worked for both devices. I also had better luck (seemingly) by telling the TiVo what MoCA channel to use, rather than just leaving it on "Auto".

    Hopefully this will help someone else if they have an issue.

    My MoCA has been using CH 15 without problems, I used the auto function and that what ch the MoCA went to.

    Dangit. The mini upstairs isn't connecting now.

    I guess I need to start chasing splitters and replacing any that aren't rated for 1 GHz. I guess that could be a cause of the intermittent issues...

    Frustrating that something that should Just Work is such a pain in the neck.

    How else is the router connected to the network -- assume the Roamio is removed from equation. Is it connected to you cable modem? The EtherNet from the Roamio to the router my have created what TiVo refers to as a loop. Which would need to be removed.

    michael

    "Check the MoCA loops

    You can only have one device creating the MoCA network. Verify that you have only one MoCA Network Adapter or 4-tuner TiVo DVR connected to your router
    Verify you have not accidentally connected both a coax cable and an Ethernet cable to a 4-tuner TiVo DVR on your MoCA network. Doing so will automatically enable the Bridge mode, and the TiVo DVR will attempt to create another MoCA network rather than use the current network."

    quoted from General Troubleshooting section of MoCA Networking support doc.

    Thanks, yeah - figured that one out the hard way.

    I've got everything working again, I replaced the ancient NIM-100 with an Actiontec device that used to provide the internet connection for my Premiere in the upstairs bedroom. Once I did that and set the FiOS router back to 1150 MHz, everything lit up and started working the way that it should. Don't know if the NIM-100 isn't working properly or configured wrong, but with it out of the loop, everything is gravy...

    Did you ever resolve your Roamio Plus setup issues? We have the exact same configuration.

    roamio plus (won't create Moca Network)
    Tried direct connect ethernet to cable modem
    Turned off cable amplifier
    Comcast

    After an hour on the phone with tech support, they're sending me a replacement unit. We couldn't get the Roamio to setup a Moca network. They had me direct connect the ethernet to the cable modem, turn off any amplifiers on the cable line, and reset the Roamio. Nothing worked.

    I really suspect that the issue is not the Roamio, but some strange issue caused by the cable modem (comcast). I guess the replacement unit will prove out that theory.

    So,i'm curious if you ever had success based on all of the forum feedback.

    Thanks - Howard

    I was having the same problem, getting the C33 error on my Roamio when trying to setup the Moca network. I finally got it to work and I think the issue was that I didn't have to do anything on my Roamio (which is my main DVR that is acting as the bridge). I think that I just needed to plug in the cable and ethernet and it started working. I was trying to setup MoCa as my network and it kept failing. Does that sound right? Nothing to actually setup on the main one if it's the one acting as the bridge?
