I was thinking of putting a MoCA-to-ethernet adapter in a remote room in my apartment so I can have an ethernet hub there. My ISP modem (its not a modem-router combo) has a MoCA port, so does that mean I don't need to get two MoCA-to-ethernet adapters? Any help would be much appreciated!
Welcome! Moca is pretty awesome for what you're using them for, and in fact you can use the g1100 router from frontier/verizon and it has a built-in switch. You just have to disable the router parts of it, and you have a moca adapter, switch, and ap all in one for under $40 used. These max out at only 500Mbps as they're moca 2.0, but not 2.0 bonded, but that should be good enough for most things. I love mine.
