Hi all,

 

All of a sudden my Samsung Galaxy Tab S8+ cannot detect my Wi-Fi 6 GHz SSID anymore:

  • Previously, the Tab S8+ was connected to my Wi-Fi 6 GHz SSID;
  • My mobile can detect and connect to the Wi-Fi 6 GHz SSID;
  • My Tab S8+ can detect the backhaul Wi-Fi 6 GHz SSID, but obviously cannot connect to it;
  • The Wi-Fi 6 GHz SSID is not hidden;
  • As a test, I enabled the Wi-Fi 6 GHz guest network - still not visible from the Tab S8+ (but visible from my mobile);
  • There are no blocked devices in the Deco system;
  • Also, a Wi-Fi Analyzer app on the Tab S8+ doesn't detect the Wi-Fi 6 GHz network/SSID. The same app can detect it on my mobile. The app does detect the backhaul Wi-Fi 6 GHz network/SSID on the Tab S8+.

 

But interestingly, both my Tab S8+ and mobile (Samsung S23 Ultra) just recently had an update to the Android OS. My Tab S8+ (and mobile) runs:

  • Android v14
  • Open UI v6.1
  • Android security patch level: 1 May 2024

 

Does anyone know if the Android OS update has a bug? I've read that previous OS versions had bugs like this.

 

Thanks,

Thomas Birk

Hi, welcome to the community.

Are you able to connect the Tab S8+ to another 6GHz network?

I did some Google searches and haven't found any similar feedback yet.

 

Did it help to restart the tablet and reset the WLAN settings on the Tab S8+?

Wait for your reply and best regards.

Thanks.
I still haven't found any other 6 GHz networks that I can test with. I will bring the Tab S8+ on holidays and hopefully find a network there.

It didn't help to restart the tablet and all Deco routers. Also, resetting the Wi-Fi settings on the tablet didn't change anything.

In the end, I will do a factory reset of the Deco routers and configure everything again.
