Yamaha MusicCast experience_mainly NetRadio

Does anyone use the NetRadio service of the Yamaha MusicCast system? I'm mainly annoyed with receiving network streams through their Airable service. Out of "nowhere" it is non-functional, it only reports "Loading..." and nothing works. Is there any way to tell if it's a network outage, or messaging, or something else? I've tried a couple of times by changing the network cable, changing to a wifi connection and sometimes that helped. But not always, which is pretty weird. Worse was that resetting it made all the presets disappear, which had to be laboriously searched for again. For 250+ stations, that's a real bummer.

Thanks for sharing similar problems and their solutions.
