Issues with MoCA 2.5 - What am I doing wrong

[AndyJT1]

So, I've got 2 goCoax MoCA adaptors working over a cable (its a joined cable in the attic, but its acting as a single cable). The connection works well. But now I want to add a third goCoax, so I'm trying to use a splitter to add the third one (building a network backbone using the coax/MoCA network). The splitter I bought is a BAMF SB-2006 which supports MoCA 2.5. But when I add the splitter into the mix, I can't get the MoCA lights to confirm the connection. I've got the cable on two of the outputs with nothing on the input connector and nothing on the other 4 outputs. The only change I'm making is adding the splitter to the mix.

I'm wondering:

1) Is the splitter, even though it supports MoCA 2.5 dropping the signal too much to allow a connection?
2) Can I just use a T junction and add a third cable to the mix without using a splitter? (Somehow I doubt this, but could I?)

Any advice?

Why a 6 port splitter ? Use the smallest one that will do the job.
How many cables do you need to connect ?
Are these RG59 or RG6 coax cables ?

A sketch of the coax network showing all devices and terminations is sometimes useful for diagnostics.

What else is on the coax cables that you are trying to use ?

BTW, i suggest using a different splitter, specifically designed and Certified for MOCA 2.0. They should have lower loss between each output port. The satellite splitters like you have may not work.

Also, place a 70 dB MOCA POE filter on the inlet port to maintain improve moca signal quality. All open ports should have a 75 Ohm termination cap installed.

Here is a previous thread that may be useful

The Moca adapter is not working , please help

Hello everyone , I didn't know about Moca adapter until a couple days ago. I was and am currently using Powerline network adapter and that is working ok but I want to take it to the next level since I play competitive online games like BF5 so I bought the Actiontech Moca 2.0 ( ECB6200 ) ...

Not really. See the following:

* MoCA-compatible splitter recommendations (… and warnings)

‘gist: A splitter can be optimized for satellite service or MoCA, but not both.

I've got the cable on two of the outputs with nothing on the input connector and nothing on the other 4 outputs.

As mentioned in one of the above links, even with the BAMF splitter, you may have luck if you were to add a “PoE” MoCA filter on the splitter’s input port, and cap all open/unused ports (including the MoCA filter) with 75-ohm terminators. (Using a right-sized MoCA-optimized splitter would be preferable, per your preferred topology.)
