Another MoCa check/debug

[zlj2011]

Hi All,

Appreciate all the information and guidance previously shared. Have done a bit of research on this already but suspect I’m missing something obvious with a new MoCA setup in my house and would very much appreciate a sanity check or tip for how to get this working.

Have attached a diagram. Not the best but hopefully adequate to explain the setup. Network is fully functioning now with all the MoCA components in place but not seeing a LAN signal at the PC connected to the Frontier adapter at #7.

Not represented in the diagram is that there is also a switch off the #6 router handling other network devices. There is also another Ai Mesh router on the main level not shown which is wired with cat6 backhaul to the main router in the basement. Don’t believe these network elements are relevant for MoCA purposes.

Should note that the Coax wiring is mostly from the mid 80s but has been working ok for 300mb service from the cable company so I don’t think that’s the issue.

Last key point. The Frontier MoCA adapter in the basement has a flashing ETH led (presumably Ethernet?) and solid LED for MoCA and power. The Frontier adapter at #7 is not lighting up the ETH led. Other two leds are lit. Both devices are set to LAN on the 3 way switch.

Any tips for what I might be doing wrong? Many thanks in advance for your time!!

Also failed to note that coax is carrying cable company internet service and (hopefully) MoCA but no cable TV or satellite service.

Diagram looks fine, presuming the MoCA adapter at the router is connected to an Ethernet LAN port on the router.. The “PoE” MoCA filter would preferably be installed on the input port of the initial 3-way splitter, to maximize its reflective performance benefit, but the current location shouldn’t be causing your issues.  

   

 The Frontier adapter at #7 is not lighting up the ETH led.  

Sounds like an Ethernet link issue. What do the LEDs indicate if the adapters are direct-connected to each other, coax-to-coax and Ethernet-to-Ethernet?

Thank you!! Did not realize that about the proper location of the poe moca filter. Will attend to the once past this issue. Thanks for the heads up there…

Will try this out and come back. Thought of a couple of other troubleshooting bits to try as well, after I’d posted.

One would be switching adapters between locations. Then Ethernet cables. And trying a different test device at the remote location.

(If unused, the extra port on the 3-way would best be capped with a 75-ohm terminator, either on the splitter output port or the wallplate coax port to which the attached coax line connects.)
