There is a pretty basic problem with Chromecast in that the app to configure it 
looks at what network the android device is on and tries to have the Chromecast 
connect to that same network. If you have different SSIDs for 2.4 and 5GHz and 
are connected to 5GHz the result is failure, even if the networks are bridged 
together (let alone routed)

I'll have to go back and test again, but I think I still had problems even after 
the initial configuration if I connected to it via the wrong network.
