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!
