Update.
I am finally getting the full 2 Gbps down and ~1 Gbps up with the MoCA 2.5 adapter. Here is what i did
1. Terminate all open coaxial port around the house.
2. Disconnected the connection from the external source.
3. Added the PoE MoCA filter you mentioned above.

No it is NOT, Santhosh. That’s the point. You missed this part. Read every single word of it from top to bottom.

Dong,

Thanks! for the quick response. the ECB7250’s theoretical throughput for the LAN port is upto 2.5Gbps. What am I missing?
additionally, I ordered a 2 MOCA PoE filter you recommended. lets see how this works

This happens a lot, Sam. Like others, you didn’t pay attention and made wishful assumptions based on the vendors marketing ploy. The speed of the adapter is limited by its network port. Give the post a careful read.

You are a reputable source and thought I pose my question to you.

My house has CAT 4, changing that is a expensive option, hence I decided to go the MOCA router. I have a 2 GB Gfiber and use their 6e router (GR6EXX0).

My set up consists of 4 moca nodes all are Screen Beam ECB 7250 with of them is the primary/master node is connected to my routers 2.5 GB port. I checked the output to confirm I am getting a ~2GB down and ~1GB Up. I plug the master to the existing coaxial outlet. after this is a blackbox, and on the other end I connected a another 7250, but get only 1.2GB. I am understand there is going to be some signal lose, but didnt expect 40% loss.
I have a finished basement and have small panel with bunch of coaxial cable connected to some splitter. I disconnected a few that I know i am not using, but didn’t help much.
I am looking for your advice on how I can reduce the signal loss and increase the speed to get close to 2GB.
1. Will adding a coaxial signal booster help?
2. Terminating unused terminals, help?

An outlet is just a terminal of a cable, Bob. You can take it out of the picture. Or not. But I can’t imagine for you. Good luck!

Which of them doesn’t need a wall outlet? In the “best practice” diagram they clearly go to different splitters. Unfortunately the diagram doesn’t show where the wall outlets are, if they are different than the coax runs.

Are you saying that the cable modem and the MoCA adapter that run to the router on their ethernet side are running to the same wall outlet on their coax side, with an additional splitter not in the diagram joining their coax runs to the wall?

You just need a short coax cable for the modem or router, Bob. Not all devices need a wall outlet (which what I think you meant by “tap”?), a simple splitter and two short, as short as less than a foot, cables will do. Have a bit of imagination and pay some attention, you’ll figure things out.

Use a different splitter, Ron. But it’s best not to use one. Read the post carefully.
