Gotta say for a retired person who was in the IT field for 30 years I'm ashamed to admit how I fixed it but it's clearly made all the difference in the world. My two mini's would regularly lose connection with my Roamio. Rebooting them temporarily fixed the issue, until it happened again, hours or a day later. The problem surfaced probably around 2.5 years ago and progressively got worse. I finally upgraded my two routers in my home to better serve my 40+ network devices to Linksys WRT1900AC routers. MUCH faster CPU's then my old faithful Netgear WNDR3700's and it is night an day difference. Plus, my internet speed tests are now consistently well over 220mbs. I'm telling you, if you have lots of network devices and an older router like I did, it might make sense to consider upgrading the router to a fast one. I could slap myself for not thinking of this a long time ago. (Trees before forest thing).
