I’m trying to install the Rachio 3 Model 12ZULWC. When I try to connect the controller to WiFi, I get a message that the controller could not be found. I am almost certain that the signal strength from my WiFi access point is not an issue.
My WiFi router is a Nighthawk AC3600 tri-band router Model 7960P.
I’ve also tried to connect to my WiFi extenders which are TP-Link AC 1200 WiFi range extender Model RE350.
Can you try creating a dedicated 2.4g network for the controller and see if it can connect to that? I would try to bypass the range extenders for now for simplicitly. If that doesn’t work I would reach out to https://support.rachio.com to help troubleshoot the WiFi.
