KDE occasionally re-asks for password

I encounter issues with my wifi, i.e.after some time of successful wifi usage, manjaro would ask me for my wifi password again. If I then cancel re-entering, but simply re-connect via the tray icon menu, it will work again.

This is my system:

~ >>> inxi --admin --verbosity=7 --filter --no-host --width

Can someone please help me in order to track this down?

Check if KWallet is enabled

Then check if you set your Wifi password to be saved to KWallet

KDE Wallet was enabled, but password was saved unencrypted for all users. This seems like a less tight setup, but I’ve changed it according to your proposal. I’ll give it a try, thanks!
