Step 3: Wiring Diagram

Picture of Wiring Diagram
I recommend that you draw a wiring diagram prior to purchasing and installing product.

The attached line drawing shows my intentions for a three room installation. The first room to start is where you'd find both an Ethernet and coax drop in the home, which is in the home office for this project. I have starred (*) wherever I am adding equipment or cables that was not there previously.

The following steps will explain the room by room installations.

Generally speaking, I am adding a coax splitter to each room. One outbound port will go to the cable set top box (STB) while the other port will go to the coax adapter. The coax adapter is then connected by an Ethernet cable to the respective connected devices.

Thanks for the MoCA info! I am hoping to hook up a MoCA system in our Adobe home which has many dead spots because the walls are so thick. Fortunately, our house has coax wired into every room. We have a utility closet where the comcast point of entry. We are only using Internet and phone from Comcast- no TV signal.

At the point of entry there is a splitter which the phone modem is hooked into and the other goes to the 1st floor office coax outlet where the modem/router (its an all in one unit, MoCA light is on) resides.

What I want to do is have 4 rooms activated with the MoCA adapters. These 4 rooms have coax outlets where the coax runs from the room to the basement utility closet, where the cable point of entry is.

My questions are:
Do I need a filter at the cable Point of Entry before the 2 way splitter?

Do I replace that 2 way splitter with a 4 way splitter or should I add on a 4 way splitter off the 2 way? if I do that will I need an amplifier?

Can I hook up a MoCA adapter right after the Point of Entry splitter then hook up the 4 way splitter to go off to each room then at the outlets hook up the MoCA adapters. Keeping the modem in the office on the first floor? Or would I hook up the modem in the basement utility closet as well?

Or does anyone know of a MoCA device that hooks into the point of entry which has multiple coax outs? And would something like that work in my house?

Thanks for any input!
