How to fix if Hyprland do not remember the WIFI connections

Info:

Sometimes when you install Hyprland on top of an other DE, especially KDE, you will notice that it may not save your WIFI connection passwords. So each time that you log in, you may have to re-enter the wifi password.

How to fix this issue?

Thankfully there is an easy fix for this:

You have to forget the connection.
Then you have to reconnect with nmcli or nmtui.

Note

I suggest you to use NMTUI as it is much easier and you don't need to remember bunch of commands.
