Some of the routers from Netgear, Asus, Ubiquiti and others have a feature in their advanced or professional settings called "Airtime Fairness" or WMM (WiFi MultiMedia). This is by default turned On and can cause devices with low data rate such as a smart plug or in this case, the Garage Door Controller lose network connection randomly or show "No Response". To resolve this issue, use the Advanced or Professional settings of your WiFI router, typically accessed via the router's Web interface, and turn off or disable the "Airtime Fairness" setting. Another wifi router setting that can sometimes cause connectivity issue for these low bandwidth devices is the QOS (quality of service) setting. Please try turning off that setting as well if connectivity issues persist. See example screen image for Netgear Nighthawk router settings screen. You may also wish to call Insignia support and request a firmware update that addresses this issue in some circumstances.
