Wireless Network Won't Talk to Data Network

I have two networks on my lan, one for all devices that are physically connected via ethernet and one for the Wireless AP. I have these configured on a cisco L3 switch and both networks have full connectivity to the router and internet via static routes on the router.

For some reason though, I don't quite understand, why Airplay won't connect to the physically connected Roku or Syncthing won't sync to my NAS from my iPhone on the two different networks when the two networks can fully ping each other.
