Hi 
I am having trouble connecting to Wi-Fi as usual (in my case that is clicking on Networks in the status bar and so on).
I am having the same problem with every Wi-Fi connection (work, phone).
However, connecting via nmtui-connect DOES WORK 
I tried to search for solutions by myself but so far could not resolve the issue.
This is my inxi output:
perl: warning: Setting locale failed.
