    A couple days ago I set up a MoCA network with a handful of Actiontec MI424-WR (rev F) routers off eBay. Configured using info on AVS forum (apparently I can't post links yet...) - basically - disable wireless, disable broadband coax, disable IP address distribution, assign unique IP.

    My setup is CenturyLink Q1000 DSL (bridge mode) -> Netgear WNR100 -> everything else. Comcast for digital TV service. I've got two TiVo Premieres, an HD, and an S3. The HD is direct ethernet; the primary Actiontec + Netgear are at the same location. Premieres and S3 on MoCA. Everything worked great, I could transfer between all of them much better than I ever could on wireless. Went to bed, got up the next morning, and none of them could see each other.

    Verified from a computer that I could not log in to the admin screen of the 3 remote Actiontecs. The primary one, connected to the router, I could get to OK. After rebooting/ unplugging/ the remote Actiontecs, everything eventually came back up. Next day, again, all had lost connection.

    The wiring in my house is far from optimal, I know there are a couple of splitters buried in walls with no way to get to them. In the interest of trying to minimize loss, I'm using a Holland DPD2 diplexer to split the frequencies at each coax outlet (vhf outlet to tivo, sat to actiontec.) I put a 4way 2-2150MHz splitter at the cable inlet - SWM MSPLIT4R0-03 - with a POE filter on the input side. Frankly I was surprised it all worked. But it did.

    I'm not including a number of details here for the sake of brevity. I can certainly provide more if it would help. It just seems like there may be something basic I'm missing in the router settings. The only other obvious thing I can come up with is trying to reduce signal loss - at the HD TiVo outlet, it reports cable strength as 62. The other TiVos are around 85-100. The HD outlet is also where I have the first ActionTec feeding into the rest of the house, so given that that line is weak, could that be problem? Can a weak signal manifest as having connection for awhile, but eventually dropping out?

    (edit - checked Coax Connection Stats for MoCA speed on the primary Actiontec - all devices appear to be ~235-240 Mbps.)

    I can run some temporary cables to other locations to troubleshoot, maybe test one coax outlet at a time - but given the connection takes hours+ to drop, that will be a long process. If it is just a router setting, I'd rather figure that out first.

    I don't think you're minimizing any loss by using diplexers and they may be contributing to the drop off. For starters, I'd try simple 2-way wide band splitters at the tivos and router.

    Tivo and actiontec router...

    My problem is caused by Verizon FIOS actiontec router bridging function. While the router allows bridging it handles igmp/multicasting in a special way.

    The router bridges ethernet/moca/wifi but uses an igmp proxy and limits the use of multicast on on theses segments. Depending on the version of the router you have you will be able to turn of igmp proxy and allow multicast to your tivo hosts.

    It also affects itunes sharing which also uses multicast.

    I previously had a TivoHD on the moca link, so i did not notice any problem. When I moved a premiere on to the moca link, the premiere which worked fine before, started showing the SDUI interface for the remote My Shows screens. And the other premieres which tried to access that unit also started showing the SDUI interface for the remote My Shows to that unit.

    It appears the new interface requires the use of multicast, I am not sure why they made this requirement as it is just 2 peer Tivos exchanging information.

    Thanks, I replaced the diplexers and the SWM 4-way and managed to optimize a couple other things. Everything seems pretty solid now, once in awhile one of the remote tivos will drop off the now playing list of the others, but a router reboot or forcing a network connection seems to bring it back up. Hopefully it will all settle in now that I'm done unplugging/reconnecting stuff.

    Thanks for the heads up, the Actiontecs have a checkbox to turn off IGMP.

    I know this is a old thread but I was wondering if anyone who was on this thread may be of some help with the moca issues I'm having with my TiVo boxes and adding actiontec moca extenders and a wireless range extender which keep taking my current network configured for my tivo boxes down.

    I feel as if there's a setting or something that may not be set right. The actiontec adapter currently connecting the current TiVos to the network is set to auto but for other settings I don't know what they'd be or how to access them as well. Here's the thread I started about my issues. Any help is greatly appreciated. Since I've only posted one thread it won't let me post a link to my thread so I had to put the word "dot" in place of the . before com or you can search for my post in the help section using my username in the search query. Thanks!

    I'm such a sucker. I had delayed responding to your original post thinking someone else might do so, first, but also because I've been bitten a few times responding to one-posters, never to hear back or see a second post. So you posted here escalating your call for help and, like a sucker, I bit. Well played...!

    Thank you for replying. Never got a notification from the forums for some reason unless it accidentally got marked as spam. Once I get a few other new house problems non related to this out of the way I'll get back on track with this if basketball don't keep me to busy with the volunteer coaching I do. Thanks again!

    Eh, sounds like you've got your priorities straight. Good luck w/ the hoops; this place will still be here on the other side.
