Windows 8 is also frustrating our network. Windows 8.1 on a Dell E5530. Secure connection. Lasts indefinitely and then must disable/re-enable wifi card to make it work. Unsecure connection has been working for 3 hours now which is longer than I have been able to get a secure connection to last. Can't say it's Ruckus or Windows 8 or some blame in both but.....
