New MoCA Network Issues (alien.top)

Good morning y'all! Working on setting up a MoCA setup in our new house and running into some issues during setup. Using these MoCa gocoax 2.5 adapters but seem to a having a splitter problem. I know MoCA adapters need to communicate on a frequency up to 1675 MHz so I bought these Splitters, one 4-way and one 2-way, thinking they would work. Once installed, the MoCA adapters are communicating but I'm getting intermittent connectivity and extremely slow internet. I had a spectrum tech out and he seemed to think that the issue was in the splitters because the signal all but died after hitting the 4-way.

Wondering if y'all think I should order these splitters to see if they work, or if y'all see any other issues from my diagram. For reference, I'm using a Spectrum Modem E31T2V1 but my own Netgear Nighthawk router.

Any help would be appreciated!

I suspect that the issue is that the MoCA signal is interfering with the DOCSIS 3.1 signal. Get a PoE Filter and connect it at the Modem's coax connection to keep the MoCA out.

Here are some diagrams from GoCoax that provide guidance. The second house diagram most likely applies to your situation.

I doubt that the splitters you are using are causing the problem. While not ideal, I have used them with MoCA for quite a while and have not had any issues.
