Moca with XD4 modem (X-2gig)

We recently upgraded to X-2Gig service and received an XD4 modem (which i understand is a DOCSIS 4.0 modem), and while the service works great at first at full speed, it drops to half speed after a few hours.  This speed drop does not happen with our MoCA adapters unplugged, so I suspect some interference with MoCA.

Does anyone have any guidance on getting the XD4 to work well with Moca?  I am a little lost trying to figure out which frequencies are used for X-2Gig, what the XD4 uses, what sort of splitters to buy, and how to configure MoCA for it all to play nicely.  Thanks.

jkruiser Thanks for reaching out! Unfortunately, we don't have supporting documentation on using MoCA with the XD4. The supporting focus is on the high upload, and download speed capabilities.

I am confused by this reply - your technician mentioned nothing when installing the XD4 into my MoCa-enabled network, no information on X-2Gig mentions a sudden incompatibility with MoCa,  the Gateway I am required to use with the XD4 has MoCa settings available, and there are many examples of users asking about MoCa in this forum where Xfinity employees say that MoCa is supported when using Xfinity-provided equipment (for example, here: https://forums.xfinity.com/conversations/your-home-network/moca-support-with-xfinity/66d2506c38e9a26c9e752678) 

I rely on MoCa for extended coverage to my condo.  Are you suggesting that MoCa is not supported with the XD4 or X-2Gig service?

@jkruiser​ I could be mistaken, but I recall hearing that a MoCA filter will cause issues with the new X-Class DOCSIS 4.0 systems. However, I haven’t seen any word on MoCA devices themselves causing issues. Heck, I haven’t even seen it discussed at all yet. 

If it was me, I’d push quite hard to get an XB10, and see whether that resolves the issues. That would be a good start, as the XD4 was really only meant to be a stopgap. 

Keep us posted.
