Q990c SmartThings connection issues

DeanySevigny — Sat, 07 Oct 2023 00:07:52 GMT

I have the Q990c soundbar, and the sound profile in Atmos is absolutely incredible. But like so many other people, it keeps “going offline”, disconnecting from WiFi and needing to be deleted from SmartThings and re-added so I can utilise the app and wireless features of the soundbar.

Has anyone found a sure fire way of keeping this from happening?

I’m having the same issue and desperate for a fix. I have the same sound bar and it was working just fine connected via Wi-Fi to my TV for about two months. One day, it decided to only be able to connect via Bluetooth and I have not been able to connect via Wi-Fi. I have to option to select the Wi-Fi connection to the sound at from the tv and get the message that the speakers need to be configured. I select it and then it gives me a connection error — however I can select the speakers via BT just fine. I’ve tried uninstalling the smart things app, resetting the speakers, resetting tv, making a new Samsung account — nothing has worked. Extremely frustrating. The sound via Wi-Fi and BT is night and day. Desperate to have this fixed.

I've been having the same issue. I've reset it and re-added it twice, which will work for maybe a day or two but then go back to disconnnected!!

Hi everyone. After stumbling on a fix that someone else tried for a different Samsung soundbar, I *think* I've finally cracked it. It's been connected to wifi and showing on my SmartThings app for over a week now!

I turned off WPA3 security on my wifi extender (Eero). That's what someone else said they did when they were having the same issue with a different soundbar, and touch wood, so far it seems to have worked.

I have the same issue with the same Q990C soundbar. I’ve had to re-add the soundbar 4 times already and it’s super frustrating. You would think if you bought a “high” end soundbar model that you wouldn’t have these super annoying issues… hopefully Samsung fixes this soon.

Since switching off WPA3 security on my WiFi extender, it’s been absolutely fine! That was over 2 weeks ago

I’m having the exact same issue. It’s a gamble every time I turn it on whether it’s gonna connect or not. Sometimes it lasts three days, sometimes it lasts a week. Like somebody stated above, at this price point it shouldn’t be happening. I don’t have an extender, so turning off the WPA3 won’t really be a potential fix for me. Come on Samsung let’s get a fix.

I’m having the exact same issue with this exact model!

Same here. Q990C sounds great when it works but that only lasts for a day or two then it will not connect to the TV. Reset everything and sometimes that works and sometimes it doesn't. If it works, it's only for a couple days at best. My samsung TV is only a month old so I would think there shouldn't be any problems. I may return the soundbar for a different brand.

I encountered the same problem with my Q990C soundbar; it wouldn't connect to SmartThings. Even when it appeared to connect momentarily, it would soon disconnect. Despite trying various solutions, like resetting the soundbar, removing it from the SmartThings app, and implementing every suggestion I found online, nothing worked. Eventually, I came across advice stating that the Q990C has connectivity issues with 5GHz Wi-Fi networks but functions properly on 2GHz networks. Upon checking my router settings, I realized it was connected to the 5GHz network. Fortunately, my router allowed me to force the Q990C to connect solely to the 2GHz network. After making this adjustment and power cycling the soundbar, it successfully connected to the 2GHz network and has been operating flawlessly for the past three days. I'm sharing this in the hope that it might help others resolve similar issues.

Same here. Can’t change the WIFI connection to 2.4 GHz or disable WPA3 to overcome this issue. This is the only device that keeps disconnecting, seems a Firmware update is needed to fix this issue. Also it should be possible to set a fixed IP address or connection speed from the SmartThings app.

I’m also having the same issue with this model. Very frustrating.

Hello All, you might want to try installing the smart things hub on the soundbar. It keeps the soundbar ‘alive’ on the wifi router. Since I did this the issue no longer presented itself. Hope this works for you as well.

I’m having the same issue but now the smart things app won’t even find the WiFi networks. I have numerous other devices connected to the WiFi including a Samsung TV

Try factory reset first on the soundbar, it should pop up after that, install both options (soundbar + hub). I haven’t had any problems since and it must be said great sound experience.

Any solution?

There is an obvious fault with the 5ghz connectivity on this soundbar. Difficult to know whether it's a software or hardware issue.

However, I found that it is stable on 5ghz when using low 5ghz channel numbers. I encountered frequent disconnects whenever my WiFi was using the higher 5ghz channel numbers.

If you can, make sure your 5ghz WiFi is using the lower channels.

Hope this helps!

Samsung soundbars are absolutely terrible. And Samsung customer service is even worse.

There is a major problem with the qn990c soundbar. And they know this but still sold them to the public. A lawsuit should be taking on behalf of the public who where sold the useless faulty products. Should of brought a Sony, or bose soundbar.

Yup, I confirm that the issue is still here, even after the manual USB firmware upgrade. 😞
