Wifi not working (0.23 version)

Hi at all, anyone has a wi-fi problem with the last update ? (0.23 version)
i can’t connect to wi-fi, i tried a simple reboot but it doesn’t work.

Just did update GS290 to 0.23 Stable. No issue with WiFi nor anything else.
Maybe reinstall 0.23 stable .img file.

But i must wipe the phone ?

Fisrt try a dirty flash (no wipe), and if still get troubles, save your files a reinstall after a complete wipe.

Can i ask you the instructions for a dirty flash ?

You might follow those instructions: Install /e/ on a Gigaset GS290 - “GS290”
