I have a roamio plus and am using 2 mini's right now in the downstairs of my home. I have a Tivo HD in an upstairs bedroom and I'm replacing it with a mini. Now I'll have a total of 3 mini's in the house to share signal from the roamio. Well the third mini won't see a moca signal at all. I get cable service fine on the outlet from the Tivo HD but the mini sees nothing. Other two mini's work fine. I have a POE filter installed. I also switched mini's. I put the new mini downstairs where one of the older working mini's was. The new mini worked fine. The old mini which worked fine downstairs I brought upstairs to the trouble spot and it doesn't work there either. So I figure for some reason moca isn't getting upstairs to that outlet. but it's getting everywhere else. Comcast says I only have one POE to the house and everything's connected, so they don't know what to tell me and they don't really support Moca . So . any suggestions?
