My minis keep losing their connection. It seems like every day now two of the three don't have a connection when I go to watch TV, and I have to wait for them to reboot- then it's fine. Now my third one just lost it in the middle of watching a show. I'm hoping that it's just that the mini's have new software and the XL4 doesn't yet (as of a day or two ago), but what else could be causing this? It wasn't happening up until recently... Would adding MoCA filters help at all? I'm currently totally unfiltered.
