After initial difficulties fully satisfied!

In the beginning, the films that I hung on Youtube for example always looked on. The whole thing was not acceptable.
Then I contacted the customer service from Samsung. The employee has taken more than an hour for me. To put it short: After I surrounded the wireless connection from 2.4 to 5 GHz, everything worked perfectly.
It now works as I had imagined. Top !!!
Again, however, a big thank you to the Samsung Service!
