For weeks I’ve been struggling with this issue: Sometimes I can’t get a wifi connection, because »no password provided«.
Leap 15.1, but current KDE.
I’m using a loopback adress for a remote desktop session. Once in a while the session gets stuck and I can’t reconnect. So restarted the network, but then any encrypted wifi connection fails:
systemctl restart network
:/home/AW # systemctl status network

What do I need to restart else?
After a reboot everything works as expected, the network gets the passwords from kwallet.
