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)

422 217.878694 192.168.6.13 224.0.0.251 MDNS 167 Standard query 0x0000 ANY Samsung QN90BA 65._airplay._tcp.local, "QM" question ANY Samsung.local, "QM" question SRV 0 0 7000 Samsung.local A 192.168.6.13 OPT

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/

444 220.215424 192.168.6.87 192.168.6.13 HTTP 305 GET /nservice/ HTTP/1.1

This returns an XML string like this:

<deviceType>urn:dial-multiscreen-org:device:dialreceiver:1</deviceType>
<friendlyName>Samsung QN90BA 65</friendlyName>
<manufacturer>Samsung</manufacturer>
<manufacturerURL>http://www.samsung.com/sec</manufacturerURL>
<modelDescription>Samsung DTV RCR</modelDescription>
<modelName>QN65QN90BAFXZA</modelName>
<modelNumber>1.0</modelNumber>
 
If anyone from Samsung tech support wants the raw Wireshark captures, I have them.  Switching to a wired connection is not ideal where this is located.   
 
Just seeing if anyone  else has seen issues with this model QN65QN90BAFXZA and WiFi.

Hello! Thank you for reaching out! Unfortunately, as we are not technicians we would be unable to analyze the information. I would, however, recommend trying the information in the following link: https://www.samsung.com/us/support/troubleshooting/TSG01111046/. If this does not help you can try calling our remote management team at 1 (800) 726-7864 and asking for remote management. 

 

After this service would be required. Depending on your warranty you will have a couple of options. 

 

- If your unit was recently purchased, you can check with your retailer on their return/exchange processes.
- If you have an extended warranty you can reach out to them to have service set up. 
- If you're within the one year warranty, you can Private message me or one of our moderators or you can call in directly at 1-800- 726-7864 with your full model and serial number to have service setup
- If you're OUT of warranty, you can use this link below to find a service center in your area.
