@goCoax I believe the link rate was ok when I connected them directly. I have a 6 way splitter at the outside of the house that has 3 connections. One goes to my main tv, docis 3.1 modem, and main moca adapter with a poe filter to the modem And one from the incoming signal to the splitter. A second line goes to my master tv with a splitter to the cable box and 2nd moca adapter. Finally the third line goes to my third adapter which gets poor signal and intermittent function. would a amplified splitter help with this instead of a splitter alone. Or would terminating caps on the non-used ports of the splitter outside of the house help with signal loss?

I have a BAMF 6 Way Coaxial Cable Splitter, Bi-Directional Coax MoCA 5-2300MHz, RG6 Compatible, Nickel Plated Cable Splitter 2 Way Internet and TV Splitter, Satellite, Antenna, Analog/Digital Connections per the manufacture description. It has been very picky in terms of the sequence of connecting the cables however. I have realized the line to the three rooms come from the three connections outside to this splitter. A POE filter is put on the mainline from the ground. I seem to have been able to keep the two adapters working and showing up, the third intermittently shows MOCA connections and will not show up on the network, though I can login into with the assigned IP address. It almost seems as it it is creating its own network when it works. After a few hours the speed dropped significantly on the upload to almost nothing and then I had to restart and it would not grab the MOCA signal.

Finally got things working. I think the splitter outside my house had some bad ports and once I switched the line everything worked like a charm, getting 900+ mbps wired which is great. The AP showed up to be provisioned and added to my tp link Omaha controller. I did not end up using any of POE filters and otherwise kept the diagram the same. Also was able to upgrade both adapters to the newest firmware.

I am still having difficulty getting the second moca adapter to work, not showing a moca signal now from the at coax line and not Sure why.

This is an accurate diagram. However, when I put the POE filter, I was not getting good signal to the house. For example my cable box went on the fritz. I removed the filter and can see my first adapter on my network. Also when I try to download the updated firmware from the support link on your website it is an invalid archive. I though maybe updating both moca adapters could help.
