    Here's what I would try:

    Boot to single user mode. Or boot rescue media and mount your system. The idea is to be accessing your system with NetworkManager not running.

    Remove the connection definition file in "/etc/NetworkManager/system-connections/"

    Remove the connection state files in "/var/lib/NetworkManager/"

    Reboot to graphic mode, and configure your connection. This should now be like configuring just after a clean install, with nothing remaining from what was previously there.

    (Before removing those files, you can first copy them to elsewhere in case you want to undo this).

    I temporarily removed /etc/NetworkManager/system-connections and almost everything from /var/lib/NetworkManager, after running "sudo systemctl stop NetworkManager.service" and ensuring the service was down (the system tray icon disappeared to confirm this). No results after restarting unfortunately. What else do you suggest trying next?

    Hi
    You don't seem to provide info on the chipset in use, not a broadcom device?

    As root user post the info from;
    Code:
    hwinfo --network

    It seems I managed to find a permanent solution, which was pointed out in the early stages of this issue. Funny enough it was the NetworkManager Wait Online service causing it. Likely because WIFI doesn't activate at boot time, and without a LAN cable plugged in the machine doesn't have early internet connectivity thus the service errors out. I disabled it as a boot time optimization after looking it up and seeing that it's useless, but after restarting I noticed all my connections are immediately working again.

    Code:
    sudo systemctl disable NetworkManager-wait-online.service
    As that service is pointless on my laptop and I have no reason to re-enable it, I can consider the issue resolved in my case. This still isn't normal behavior and will likely cause headaches to other users, so I'm leaving the discussion open for the team to debug it. I'd suggest booting a machine that's not connected to the internet via any connection that can be immediately detected (eg: cable internet) to get a complaint from NetworkManager Wait Online, then seeing if this causes WIFI connections to be missing after you log in.
