Maybe you didn't add the connection as a system connection this time.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't know what that means. Mind explaining?
In the Networkmanager you can set that a connection is either available to all users or just yourself. If you set it to "all users" its configuration will be saved somewhere in /etc/Networkmanager (I'm too lazy to look up the real path) and will therefore be available for Networkmanager on boot. If you just make it available for yourself Networkmanager will only attempt to connect after you log in.
I think the default is to make it only available to yourself, because then you don't have to enter your sudo password when you set it up or want to change something. The downside is of course what you describe in your post.
Perfect, thank you!
I think the connection is made by some program after login and not automatically by the system as in other operating systems
If for example i install icewm on kubuntu I don’t have Wi-Fi connection at all
I remember having to go out of my way to get an Ubuntu machine to connect to WiFi before login for this reason. It felt strange to have to do that at first, but it's also reassuring that the machine isn't by default connecting to a wireless network without user input first unless I give it explicit instructions to do so.
I actually like that. Have to put in the password on fist boot before network will connect to wifi.
Network Manager?
Was playing with KDE on live boot today and noticed WiFi took a long while after entering WiFi creds. Didn't bother digging into why, though.
You could probably fix this with some troubleshooting. That's all I ever did on Ubuntu and it's derivatives.
