A33/5G - WLAN can not be switched on

[Hank13th]

My A33/5G runs on Android 15 and One UI 7.0. Last update took place more than a month ago. Now suddenly I can not turn on my WLAN anymore.

In the context menue I can click on the WLAN-symbol, it turns grey but not white afterwards. In the settings menue I can "move" the WLAN slider, it moves to the on-position and turns dark grey... but it is not switched on (stays dark grey and no WLANs detected). After leaving the menues and coming back right away the WLAN is turned off.

I tried the following without success:
Turn flight modus on and off again...
Reset network connections...
Restart of phone...

Any suggestions or hints??

Try diagnostics via Samsung members app

I have tried that in the meantime - but when it comes to the WLAN-test the members app asks me to start up the WLAN... And I'm not able to start it (see my first post) - all the other tests of the app run ok without problems.

It will need to be looked at. Sounds like hardware failure
