I had thought that when a brand like Denon such problems are rare individual cases. Now I belong to the ranks of those who hammer out any connection to the WLAN, although all the rest will work! On top of that I have to now having trouble with the dealer, because he thinks that it was an isolated case but and Denon is the judge probably already. Super annoying!

Since it runs smoothly and as far as I am also satisfied. However, I am umgestieben of wireless LAN operation. Let's hope that it satisfied his many years to come with the!
