I’ve used this model for a few networks and had a good time. Minimal setup and supports a WPS-like security.
See the diagram in this guide: https://www.motorolacable.com/documents/MM1025-QuickStart-re...
Note both the usage of the PoE (point of entry, not power) filter, as well as the MoCA network encapsulating both DOCSIS and Ethernet traffic.
Some set-top boxes and modems are MoCA compatible, but I prefer using a discrete unit.
