Same problem in Bosnia and Herzegovina. I have Yamaha R-N301 , and no intrenet radio since yesterday.
Obviously they are making fool of us with answers like this. This is not unstable conection with some Yamaha products, as they said.
vTuner has new page and Yamaha is not listed as partner anymore, and anyone can check it on their web site.
If they don't find solution soon, many of us will aviod Yamaha product forever.
I know that doesn't mean too much for corporation like Yamaha, but for our money we deserve better costumer support,at least.
