New to MoCA, no clue what I'm doing. Trying to make my first MoCA network.

[Rob Q]

I would like to make a MoCA network that connects my Tablo (in the basement - rec room) to the router upstairs (M1 red line) and connect an access point in the living room (AP2) to the upstairs router (M3 yellow line) but I have no clue what parts to get or how to set it up. I was told to get the MoCA 2.5 adapters, so I might get this.... ScreenBeam MoCA 2.5 Network Adapter for Higher Speed Internet, Ethernet Over Coax - Starter Kit (Model: ECB6250K02). To join the coax from the room with the router, to the living room coax line, I would use this... VCE Coaxial Cable Connector, RG6 Coax Cable Extender F-Type Gold Plated Adapter Female to Female for TV Cables,2 Pack. I don't think I'll need a filter because the main cable line to the modem I won't even be touching, as it and the coax to the Tablo will be isolated. Any help would be greatly appreacted, and try to keep it very simple, just list the parts and say... just use this.

Or would I be better off and get a Mesh system and connect it to my main router and place a node in the basement for the Tablo and another node in the living room?
I've learned that a WiFi extender is bad because they'll cut the speed down in half.

If i understand your sketch correctly =

Red and Yellow are isolated runs of coax - correct ?

Green is ethernet ?

What is blue ? Is this an OTA TV signal to each TV through existing coax ?
What is a TABLO - is it a TV signal converter to digital (ethernet) box for streaming from an antenna ?

What is the mess in the snip below where all the colors meet supposed to be - it looks like ethernet, 2 coax cables, and ?
What is it you want to do ?

If what i assume above is correct, and you do not need to send OTA TV signal across the coax in the house, then simplest and highest bandwidth solution is 2 pairs of MOCA 2.5 modems (one for RED, one for yellow), a 5 port gigabit unmanaged switch ( for the snip above),.
If you need ethernet to TV3, then just add another pair of moca 2.5 modems.

If you need to send TV signal over the coax that MOCA is using, you will need to select MOCA modems with a separate coax port for TV signal. Actiontec 6200 moca2 modems are an example. Many of the MOCA 2.5 modems DO NOT HAVE this feature. You can use a moca2 rated splitter just ahead of the moca modem if you need to send TV signal to the TV on a separate piece of coax instead of using a moca modem with a built in diplexer.

Green is ethernet, yes. Red and yellow are isolated runs of coax, so you are correct there.
The blue is just how the coax is now, 3 TV's attached to a splitter (output) but I've removed the antenna feed from the input and connected it to the Tablo. That's a network DVR with an ATSC 1.0 tuner.
And yeah, I suck at making drawings. haha!

What I would like to do it use the coax that's going through the floor in my bedroom and connect it to the line going to the living room, that would convert it over to an Ethernet cable. Then I would connect one Moca adapter to the one end of the cable and connect it to the main router, and the other end, which would be in the living room, would provide internet access through the coax jack in the wall, through the Moca adapter. This way I don't have to count on the weak WiFi signals to do the job.

Also, I would like to have one line going from the main router in my bedroom, to the basement where the Tablo (DVR) is. I would connect the Moca adapter to an ethernet cable and plug it in the Tablo.

So, bottom line is that I just want to provide internet to the more areas of the house through the existing coax.

Hope that helps.

This was what I was leaning towards, yes. Could I eventually add an 2 way splitter? So, the input would be the line running to the adapter with the router, output 1 would be the line going to the living room, and output 2 would be the line going down to the Tablo DVR's ethernet port in the basement?

But with a splitter, I'd get a loss of 3.5dB per port, yes? What could I do to compensate?
