Last few weeks the app cannot connect to router, so it's become essentially useless. It's installed on this device, so obviously, I'm connected. A BIG problem for me is that even when it did work, it neither saw nor could block the Asus Extender we use to boost wifi to the kids rooms for gaming, and it's annoying to have to unplug it every night to get them off. It was good, when it worked, and I especially liked the ability to create a schedule to block access.
