Hi @albrektson I understand the frustration with having difficulty with the on-hub router. We've had success with On-Hub routers in the past. Biggest thing to keep in mind is that the on-hub has no way of disabling the 5ghz band, so if your Rachio Controller is within the distance of the 5ghz band, it will attempt to connect to that band. Can you direct message me your email that you are using with your Rachio Controller? Once I get that I can do a bit more digging as to what is happening, Thanks!
