I can’t connect either. Every time I try to connect to WiFi, after it fails to connect I get an Rachio option to retry or cancel. I have a Gen 3 model.
I have a NETGEAR Orbi mesh network. It failed to work with this, so I added another AP that is broadcasting only 2.4 ghz and I still cannot connect with that AP. (The AP has a different SSID)
I ran the wifi tool using the 2.4 ghz connection: Q7R6YTPG
