In fact I cannot think of a good title to describe this.
We know that the list of wifi connections are always changing due to the signal intensity.
When I first booted the computer, the Wifi window is like this:
Wifi 1 Wifi 2 Wifi 3
and as I was entering the password of
Wifi 1 the list changes to:
Wifi 2 Wifi 1 Wifi 3
Then my password is linked to
Wifi 2 but it is the password of
i.e. I entered the wrong password and cannot connect to any Wifi. I have to wait the list to remain stable.
So a window like GNOME which has a pop-out password window may be better?
This bug occurs when I installed manjaro for the first time or I go into a new Wifi environment.
