Do you have guest network? Generally when the 2 components are NOT on the same network, these issue happen. Make sure your Wireless and Ethernet network are the same. Or at the least your wifi is not connected to a guest network.
Just a thought, as it happens sometimes between my laptop connected to the ethernet and the iPad which is wirelessly connected.
