I have been fighting WiFi issues with this Samsung QN65QN90BAFXZA TV off/on for some time now. I would occasionally see a message from one of the streaming apps say something like "Your not connected to the internet" (varies depending on the app). I started trying to narrow down the issue. I have a relatively large number of devices (50+) on my mesh WiFi including a number of other Samsung TVs. None of them exhibit the behavior of this device.
I started with a continuous ping to the device and sure enough when the streaming was interrupted there were ping timeouts. Dug a little deeper and started some Wireshark traces from the same machine I was running the ping from. What I noticed was that at the same time the TV was dropping pings, it was also sending out MDNS (related to AirPlay)

Turned AirPlay off and that went away, but did not completely resolve the issue. I also noticed at the same time of the ping timeouts often a web service call to the TV on port 7678. (i.e http://<tv ip:7678/nservice/
