My controller has been losing connection to the internet everyday for about two weeks. The controller light stays solid and my app says the controller is offline. I can only reset the controller by physically disconnecting the power supply for 10 seconds and rebooting. This is getting anyoying and is becoming a daily routine. I have a wifi extender 2 ft from the controller location as well. If I can't depend on the controller to stay online, what's the point of having an internet based sprinkler system? What steps can I take to make the controller stay connected to the internet?
