Hello! I use an Arch Linux distro with KDE on an ASUS X570 board that has built-in wifi. The issue is that I can’t for the life of me get the wifi to work without asking me for the wifi password what feels like every hour. The hardware is active, the software is active, Network Manager is active, the wifi profile is fine, the SSID is fine, the security type is set properly, the password is saved and set to use for all users. I’ve tried restarting Network Manager, installing Network Manager with iwd backend, updating my system, restarting my system, and using nmtui to force home wifi.
Help
Try installing kwallet-pam. It will remember your secrets through PAM when you log in. Arch does not have kwallet-pam installed by default unless you install via plasma-meta package.
If you use Chromium, you will not be asked for creating a password store as well so that is another bonus for kwallet-pam.
I do indeed have plasma-meta.
