the same problem. it is probably a common problem that occurs on different
iPad models. Clients connected to wifi lose their connection to the default gateway (and of course the public Internet) for about 10 seconds; after that, all applications/connections will automatically reconnect. This does not involve a drop in the connection to wifi. At first, Ruckus tried to explain that this is a GTK / PTK corruption issue related to WPA2, which can only be solved by upgrading to Sierra, but this is not useful.
