Thanks for the additional info Linn.
My Orbi router and 2 satellites are on the latest firmware, and have worked very well for all of my wifi devices
(including 8 high res wifi cameras) except the Rachio.
I’ve done RouteThis with Rachio support before, and we didn’t get anywhere. After I added the 2nd Orbi satellite near the Rachio, everything worked well for several months. But the Rachio has mostly been offline for the last 2 weeks or so, despite constant reboots (including the Orbi and satellites).
I’m not going to replace Orbi after such a significant investment, and when everything except Rachio works.
