My setup is working fine 95-99% of the time.even when the cable modem says it can't find a downstream channel, my internet is working fine the vast majority of the time and still getting great speed most of the time. I'm not sure I could completely get away from the splitters due to the way my house is set up, because I'd still have a 2-way splitter after the cable comes out of the ground, and then the 2-way splitter that splits the cable between the modem and the MOCA adapter (the ActionTec Screenbeam ones only have one COAX connector and one ethernet port).Ī diagram of what I think your proposed setup is of moving the filtersĪll that said, I may just leave things the way they are for now. Thank you so much for your detailed thoughts. You might consider getting in touch with Comcast to ask them to see how well they think your cable modem is operating. That might require moving your Nest WiFi Router, but if the signal quality in that cable plant is such that the modem is struggling, getting the modem closer to the outside line without any filters in the way would improve things. Ideally, a two-tap splitter from the outside line with one tap feeding the cable modem directly, and the other tap with a MoCa filter on it that then feeds everything else in the house. I would try to simplify as much as possible. Ideally, the cable modem would be outside your MoCa network upstream rather than downstream from two filters. Make sure all of those runs are in good shape (tight connectors, etc.) and that there aren't any unterminated runs (coax that goes somewhere and isn't plugged in to anything, but also any unused taps on splitters – those should all have terminators on them as well). Having those two MoCa filters upstream from the cable modem isn't going to help the signal quality, and neither is having all of those splitters.

It is definitely more complex than ideal. Your MoCa network looks right to me (mostly). At least you know the Nest WiFi Router is sending the traffic out. I didn't think that was possible for that modem, but I can't come up with any other reason it wouldn't be responding. I almost wonder if your cable modem has been reconfigured to use a different address. The cable modem shouldn't be sending the traceroute probe packet any further, and the upstream router definitely won't send it any further since it's in a private address range. It's made me wonder if the cable signal or splitters may be contributing to these occasional issues. I've also had some occasions where my internet speeds fall to 100-400 mbps (even during non-peak hours like very early morning). Overall internet connection tends to work fine but I have had an occasional stability issue where I'll lose internet connectivity for perhaps a few seconds. I know this can happen if you have too many splitters and your cable signal is a bit weak. However, what's gotten me interested in testing my cable modem signal is that my Netgear CM1100 is showing a flashing green downstream channel, indicating it's looking for a downstream channel (it's showing it right now even as I type this, and even after doing successful speed tests clocking around 750 mbps from my desktop). Also getting around 750ish when I directly connect laptop to other Moca adapters in house. Getting 850 - 900 Mbps from cable modem to Nest router in office (when I run the Google Home speed test).

Network cable from Moca by TV is hardwired into TV.Īll Moca Adapters show green indicating successful Moca connection. Network cable from Moca in bedroom goes into another Nest wifi router (for wired backhaul). Each connection coming into the house has another ActionTec Moca 2.5 Adapter. The other two outside lines go into bedroom and by TV. Other line of splitter -> ActionTec Screenbeam Moca 2.5 Adapter -> Ethernet Cable -> Unmanaged Network Switch -> Ethernet Cable -> Nest Wifi LAN portĭesktop computer is hardwired into the same unmanaged network switch

One line of that splitter -> Another Moca PoE filter -> Cable Modem -> ethernet cable -> Nest Wifi Router WAN port One line from splitter goes into my office (where cable modem is). Outside house cable out of ground -> MOCA PoE filter -> 3-way splitter -> I'm wondering now if perhaps the Moca setup has something to do with this. When I run traceroute, I get 192.168.86.1 (Nest wifi router) and then 96.120.101.201, which looks like is Comcast (my cable provider), then it times out.
