Q990c SmartThings connection issues

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?

Hello.

After a lot of testing and with firmware 1004 (there is none later until today), I confirm that at least in my case I got a super stable solution (although it is a patch, the bar should work fine so I don't have to look for alternative solutions).

In my router configuration I have Band-Steering and WPA3 support (in addition to WPA2) enabled.

Both WPA3 and Band-Steering (I have tested them both separately), cause the bar to disconnect from time to time.

The only solution I have found without touching my configuration (I have many devices and I find it a nuisance to separate the networks by removing band steering or forcing WPA2) is to create a new 2.4 GHz or 5 GHz SSID (can be hidden or not, it doesn't matter) with WPA2-AES (don't use WPA3) and connect the bar to this new SSID (don't configure in isolated mode).

This last combination is the only one that works well and does not cause outages of any kind.

Greetings

Thanks for doing the troubleshooting. I've just applied your fix with a guest network, 5ghz, WPA2, no isolation to see how long that will work. Time will tell.

Thanks for sharing your solution. I just finished configuring the devices and am starting to test 🎵

 

Some additional info:

In Smart Things make sure that the soundbar is connected to the correct network. In my case, even after resetting the soundbar to factory settings, it automatically connected to the previously configured network and I had to struggle to change it

Thank you for trying to fix this but the fact of the matter is it shouldn't even come to this point. Not everyone is tech savvy like you (whether everybody thinks this or your fix is easy to do). 

For such an expensive soundbar it shouldn't fkn come to this point. Bloody Samsung man.

Totally agree. The solution should not be so complex. It is a Samsumg problem

Should be fine. 2.4 or 5 GHz can be used, it does not matter

I confirm that the rom64k solution works. I've been testing it for a couple days and the soundbar's internet connection still works.

It's a shame for Samsung that they released such a *****, no one without technical knowledge can handle it.

This soundbar also has other problems, in my case eARC communication with the TV does not work, so I am unable to use Dolby Atmos.

I would never buy this set again.

What brand and model is your TV?

I have a LG OLED77B23LA but in general it’s just a LG B2. 

Initially, I assumed there were problems with the TV. The LG service even replaced the entire TV motherboard, but it didn't help because the soundbar is a problem.

I think that not everyone is aware of what eARC communication enables, so the problem is not often described on the Internet.
