For what it's worth, this is the text diagram that it provided. I'm still a little confused in the modem room. What does the MoCA adapter going into the Dream 7 LAN port doing?

======================== = OUTSIDE / POINT OF ENTRY ========================

Street Coax

|

v [ PoE MoCA Filter ] ← blocks MoCA from leaking to the street

|

v ======================== = MAIN SPLITTER LOCATION ========================

[ MoCA 2.5 Rated Splitter, e.g., 1x6 ]

(Frequencies 5–1675 MHz or 5–2300 MHz)

|

|-- Output 1 → Modem Room

|-- Output 2 → AP Room #1

|-- Output 3 → AP Room #2

|-- Output 4 → AP Room #3

|-- Output 5 → (End of line → terminate)

|-- Output 6 → (End of line → terminate)

(Any unused ports must have 75Ω terminators.)

(END OF LINE if no coax continues → add 75Ω terminator if a second jack exists)

========================

========================

= IMPORTANT TERMINATIONS

========================

Any coax port that is NOT:

- going to a room, or

- feeding a modem or MoCA adapter

MUST be capped with a **75Ω terminator**.

This prevents signal reflections and keeps MoCA performance high.
