A:Answer No. Long-ish version is that we thought it was due to our Netflix subscription so we made sure that all other devices were logged out of Netflix. That actually worked.
When it happened again 2 days later, we did the same thing but this time TV still did not connect. I went through owners manual, the online support tool, called Netflix, called Samsung who tried to be very helpful walking me through steps to reconnect. Most of the steps were ones I had already tried based on the owners manual and online support tool. Our call was disconnected but the rep did call back. After exhausting all other avenues, the final step was the traditional IT Support guidance.....unplug it, wait a 20 seconds, plug it back in.
Which I did. And it worked! Down side was that I had to re-do some of the TV setup which was slightly annoying as other devices needed to be reconnected. The only thing that auto connected was our Wifi.
Hope this helps. If it doesn't, unplug it. :)
