SOLVED : Are MoCA adapters allowed by Xfinity....

Finding mixed answers to my questions, so I am looking to clarify.  Are MoCA adapters allowed to be used by my client PC's to access the Internet while using an Xfinity modem/router.  I purchased a MoCa adapter for one of my PC's and I get a link lights for MoCA and Ethernet, but no activity.  No data appears to be traversing the wire.  I have a the following setup : 

A MoCA adapter connected to my PC via Ethernet cable and to the wall Coax outlet.

I have enabled MoCA in my Xfinity modem.

I have ensured that the MoCA adapter outlet is connected to a MoCa compliant amplified splitter ( supplied by Xfinity ) that has a built-in PoE filter.

Modem is connected to the same splitter, but no MoCA adapter at the modem side as the modem is MoCA capable.

Does this sound right?  Any ideas why I am not seeing data traverse the wire?  Thank you in advance.

SOLVED : After a ton of troubleshooting and research not documented here, I found an article indicating that Xfinity DVR's ( which I happen to have ) use MoCA for on-demand content and operate at the lower end of the D Band around ~1100 to ~1200 ( I can't remember exactly and can't find the article now ) and the article went on to say that you need to configure your MoCA adapter to use the High D Band (~1600 ) so they don't interfere with each other.  After configuring my adapter as such and rebooting the Xfinity modem, I now have a solid and reliable connection that is faster than I was able to get over wireless.  Not sure if it is because I bought a cheaper/older MoCA adapter ( Motorola MM1000 with only MoCA 2.0 ) and that is why it didn't negotiate up to the better and of the band or if MoCA even negotiates at all and that is something you just need to know and set.  I have been troubleshooting this for over a month where it would randomly start working and if I disconnected it, it would stop working until it would randomly start working again.  Hopefully this helps someone else out.

@ttjames The community recommendation is to have the MoCA Adapter on the modem side. For more info/details check this thread https://forums.xfinity.com/conversations/your-home-network/has-anyone-successfully-setup-and-used-moca-on-xfinity-modem/61a8da3776baea4aa19fd217.

What is the reasoning behind the recommendation to having an adapter on the modem side?  I am curious.  Additionally, the link to the article does not address my question. Regardless of the reasoning for the recommendation, I wanted others to know  that my setup is working now configured as I had described.  I did nothing other than getting busy for a few days and walking away from this PC leaving everything connected as described.  When I came back to begin troubleshooting after a few day I found the new adapter connected to my network and seeing data traverse the wire.  I have heard the Xfinity modems can be finiky, but was looking for a more solid technical answer or explanation.  An answer continues to elude me.
