App used to be very useful for checking WiFi connections and devices connected to my router. Overall, this is a good and useful app when it works properly. However, recently after updating firmware on my R7000 router, the app will no longer let me log in showing Logon timeout errors which seem to be a common problem. Tech support refused help. Not sure that I could ever recommend Netgear again after having had so many problems over the years with their firmware updates and terrible tech support.
