Hi,
I'm running an up-to-date debian testing and kde plasma version 5,10.5. After a recent upgrade network manager now fails to automatically connect to my wireless network. The connection fails with a "connection deactivated" notice. After that I can connect by manually selecting my network connection from the network manager's list of available networks. But I wonder why it has stopped working automatically? Has anyone else encountered this problem?
