Can’t get Screenbeam MoCA to work :(

Hello,

I’m really struggling to figure this out.  A tech installed our modem/router in our garage.  We live in a 2 story home.  We have been experiencing several issues in one of our rooms upstairs. Our plan is for 1gig speed (fiber optic).  This room tends to get 56-200 mbps at best.

This room is used for music and video production.  It’s very important to have fast internet in this room.  I have a cat5e in our phone jacks.  I considered going this direction and changing them to Ethernet/data ports.  A few steps seem a bit overwhelming so I opted out for Moca adapters.

I recently bought a pair of screenbeam (ECB7250K02).  This is how I tried setting up.

Adapter 1 (garage where modem/router are located)

Splitter

Out - coaxial to modem

Out - coaxial to screenbeam

In  - coaxial home (couldn’t find the right cable)

Adapter 2 (upstairs)

Wall outlet - coaxial - screenbeam - to kvm  switch - MacBook

The adapters are not syncing.

The biggest challenge is adapter 1.  I have no clue which coaxial cable is should be connecting up.

I’ve never use any coaxial cable.  I read that the coaxial connections are usually outside.  SO I went outside and found a mess of lose coaxial cables left in the open.

I left both adapters on.  I figured I’d tried to figure which coaxial cable outside was the correct one by taking out the IN from adapter 1, and try each cable 1 by 1.

Unfortunately none of them worked.  I uploaded a picture of the random coaxial cables that I found outside.

I honestly don’t know what I’m doing or how to make this work.

Please, any help is appreciated.  I m really hoping to get this working.

Kind regards
