@RickW   hi did you get this resolved?  i'd also like to know how.

  @nrjessup Not resolved to date. TPLink support stated that MOCA is not compatible with their devices. However I there was a tech person who did get MOCA and a XE75 satellite to work. I cannot remember the link that had the resolution. Let me know if you are successful. Thanks!

  @RickW Since you may be receiving tech support from someone in China I'm afraid there's a language barrier issue.  The reason it is not compatible is because it doesn't have MoCA.  That doesn't mean you can't get the pair of MoCA devices and connect them.  It should work/mimic Ethernet.  They aren't common (at least not here in the USA) but are available.  You'd need a pair/set.  (Yes I have seen single ASUS routers with MoCA.  Not sure how you'd use just one except if you already have another or just a simple router with no MoCA).

I could not find a TP-Link MoCA by Google search.  But I do know ASUS ZenWiFi AX Hybrid (XC5) is a combined router MoCA unit available as a single or pair....

  @jzchen   Thanks this is helpful.  I have a moca enabled router (the old Verizon Fios one) which if I understand right, I could leave as is connected to the co-axial and then connect that to the Deco satellite via ethernet.  i am wondering what other configuration I need to do both at the moca router side as well as the deco side to ensure that the backhaul is enabled.

My issue is I have AT&T U-Verse which provides internet as well as wired coaxial TV service. I have not cut the cord so to speak for the TV service. This is the problem for me, for MOCA is not compatible with AT&T u-Verse. I found AT&T technical support useless.

Here’s a link that I found helpful, perhaps you can find it helpful as well.

Good luck. Let me know how it turns out!

  @nrjessup I recall reading that FIOS used the coax to bring "fiber" into the house.  So fiber to the outside of the house, MoCA-coax into the house-MoCA, and ethernet to your modem.  Not sure I understand what you're trying to do?...

  @RickW  This is what you want to do..I have two of these, which come in two packs for this reason.  search go coax.

Can get on Amazon.

Then follow these steps.

Recommended Setup: Own Router + MoCA

1. Coax line from the wall → AT&T (in bridge mode).

   • Gateway is acting only as a modem.

   • It passes the public IP to your own router.

2. Gateway Ethernet port → TP WAN port.

   • Your router is now in full control (DHCP, firewall, Wi-Fi, etc.).

3. Add a standalone MoCA adapter near your router.

   • Connect the coax line (split with a MoCA-rated splitter if needed).

   • Connect Ethernet from the MoCA adapter → one of your router’s LAN ports.

   • This “injects” MoCA networking into the coax in your home.

4. At each coax outlet where you want Ethernet access:

   • Plug in another MoCA adapter.

   • Connect Ethernet from the adapter → device, switch, or mesh Wi-Fi node.

• Ensure all coax splitters in your home are MoCA-rated (5–1675 MHz).

• Install a PoE (point of entry) MoCA filter at the main line where coax enters your home. This improves signal strength inside and prevents MoCA from leaking outside.

• You can expand to as many rooms as you have coax outlets—just add adapters.

  @RickW MoCA is limited to 1125 MHz - 1675 MHz, switchable between 1125 - 1625 and 1275 - 1675 (Cable Modem Compatible).  Looks like it may be compatible with Uverse, just make sure you find and install a MoCA PoE filter.

  @Webdawg  hi thank you for all of this.  I am prepared to go the two moca adapter route but what I am wondering is if I can use an existing moca enabled router (Old Actiontec MI242WR) to pass thru the internet signal so to speak and then connect a Deco via ethernet to that old router.  The main router is a gigabit router connected to the ONT in another part of the home.  I believe I can buy two moca adapters like you've outlined and use one at the main router and the other at the location I'd like to extend coverage to.  I am trying to figure out if I have any use for these Actiontec routers that can be used in place of a standard Moca adapter like the one you've noted.  Thanks!
