Need help setting up a MoCA device on an TP-Link Deco (XE75) AXE5400 Tri-Band WiFi 6E Mesh System connected to an AT&T U-verse BGW210-700 gateway. I currently have the main Deco router connected to the AT&T U-verse BGW210-700 router/modem which is set up in pass through mode. The other Deco satellite unit is connected via wireless backhaul. I have coaxial cable setup throughout the house, and would like to use MoCA for the Deco satellite unit to be connected via wired backhaul.  Can you please help. Thank you!
