DENON Ceol N9 Wi-Fi and webradio issues


I recently bought a DENON Ceol N9, a mini hi-fi system that aim to be fully connected.
With it, you can of course listen to music on CDs, FM and AM radios, USB drives... but it is also possible to listen to webradios or play music using Bluetooth (devices can be paired with NFC) and UPnP.
It sounds interesting, doesn't it? I was very excited when unpacking it. Connect speakers... done. Connect power supply... done. Connect FM antenna... not needed : I will use webradios instead of the FM that is pretty bad in the countryside.
Now all is ready, let's turn it on...
It seems to work. Oh! It says hello!
