Query: One of the main reason to buy the TX-NR515 is the internet radio function; unfortunatelly I couldn't enjoy it in a 100% , because I having problems with the wireless network performance; I purchased the  onkyo UFW-1 and  I made  several changes to improve the signalization  and now it looks ok  (78% ), when I use Vtuner or aupeo for example the audio is good in the first 20 secs, and then stop and go with a buffering process; I hope the problem will be  with my internet provider.
