KDE applet for network manager. "link is not ready"

Hi,


I have a problem with my connection with the network manager, which happened since my last update of arch, combined with the reset of the router. I can't connect to the network (internet) through the KDE applet. It was concerning both the ethernet and wifi connection. (I know, only one is necessary at the same time. Btw, how to ask network manager to prioritize the RJ45 to the wifi when available?)
I managed to fetch back the ethernet connection through "sudo nmcli". Thus, it doesn't seem to be a hardware of firmware problem. And since then, my ethernet connection is working. However, I would like to avoid doing it for the wifi, and mostly every time when I need to add a new wifi.
Still, I will provide the relevant part or the "lspci" for the sake of completeness.

I have more precision through the journal.

Thus, it kind of is like if the command can get to the network manager, but is refused. However, the nmcli in root seems to work.

I thought it could be a problem of permission. Thus, I added myself to the wheel group (https://wiki.archlinux.org/index.php/Ne … ermissions), then reboot. But it didn't fix the problem.
What could it be then? And how to make the KDE network manager applet work as it used to be?


Thanks!
Cheers
