Advertisements I have my nighthawk modem/router combo, Xbox and Tivo Roamio all connected via Ethernet in the basement. I use a Moca adapter to get a connection to my Tivo Mini in the room upstairs. For the past couple months we have been getting the V87 error on the Tivo Mini. I have tried to upgrade the coax splitters and POE filter but nothing has worked. I just went into my router settings and gave both the roamio and mini static IP addresses and it seemed to fix the issues but when I turned on my xbox in another room the mini instantly got a V87 error. Has anyone ever run into a problem like this before? I am thinking the problem has something to do with the nighthawk modem/router or the actual coax cable. I have tried to replace everything else. I am lost and ready to get rid of Tivo.
