Sound Bar Q990C WiFi Disconnects

I have recently replaced my Samsung HW-Q90R with a Samsung HW-Q990C. One of the main reasons for replacing the older item were the problems with WiFi which continually disconnected, unfortunately I have the same problem having spent over £1000 on the new system.  I have not contacted Samsung as there is little point, they either do not answer or suggest there is a problem with my Wifi signal at home. There is nothing wrong with my WiFi I have many devices connected to WiF and they do not drop out at all. There is no doubt in my mind that this is a Samsung problem, not only have I had two Samsung systems with the same problem but reading on here, there are many others suffering the same problem. I do hope some one from Samsung reads this and comes up with some way of solving the issue.

Hello,

TLDR: Q990C seems not handling WPA3 well. Try WPA2 only.

Details: Q990C keeped disconnecting. I tracked down that it occured when my router restarted. All devices were connecting back, except Q990C. I had to reset and reconnect to SmartThings every time.

There a lots of forums there related to this issue. I read many hints, including let it connect only in 2,4 GHz / 5 GHz, set up it as SmartThings hub (bottom of the control), use only lower channels etc.

Finally I downgraded my WiFi to WPA2 only (not WPA2/3 mixed, because in this case it uses WPA3). Since then it seems stable.

I do not understand why Samsung won’t fix this in a brand new device, otherwise it is a great bar. But I have doubts next one will be Samsung if they won’t fix it.

Thanks for this but my WiFi is already WPA2 so unfortunately that doesn't seem to be the answer in my case. As you say there are lots of different things to try but it is absolutely disgusting that Samsung seem to be doing nothing about a problem that lots of us are having. I'll keep trying all the different suggestions though.

Please share your circumstances.

  • Which vendor of your router?
  • Are you using any mesh?
  • WPA2 only then (are you sure it is not mixed?), but 2,4 / 5 GHz? Have you tried both?
  • I guess it can connect, how long until it drops? Do you need fully reset the soundbar then or restart / unplug?
  • For testing have you tried placing your router next to the unit to completely eliminate possibility of interference?

My internet is via Virgin Hub 3, although I do not use the wireless part of this, instead all my wireless is on a Deco M5 Mesh. I am sure I am using WPA2 ONLY. I have tried 2.4 and 5GHz and have the same problem using either of them. It usually drops overnight, I usually have to do a complete reset, removing the speaker from the Samsung App and disconnecting the mains supply to the speaker, reconnecting then adding the speaker again. I have tried moving the Deco unit closer to the speaker but I still have the same problem.

I have tried all the various 'solutions' to this problem but none of them work all the time. The unit connects and stays connected for a couple of days, sometimes less. It really is time Samsung sorted this out.
