Needed MOCA connection to Mini from Roamio OTA. Have eithernet and coax to Roamio in living room but only coax in bedroom Mini. Found Actiontec WCB3000n on Amazon for only $11.79. It works! Connected 3000n to router via ethernet, and Mini to its coax port. Have to look on your router GUI to find the ip address it gives the WBC3000n so you can access it's GUI. You can do a Google search to find out how to turn off WiFi on the WCB3000n if you need to.
