    [LAPTOP] No automatic connection to WLANs with hidden SSID after upgrade to 20.04

    This weekend I finally upgraded my MacBook Pro from Kubuntu 18.04 to 20.04, but unfortunately this has resulted in some minor and not so minor problems.

    Not being able to automatically connect to my two WLANs with hidden SSIDs afterwards is one of them.
    Kubuntu 20.04 does automatically connect to both of them if I make the SSIDs visible in my router's settings.

    What I did do:
    I wiped the Kubuntu partition of my hard drive and did a fresh, full Kubuntu 20.04 installation with third-party software for graphics and WiFi hardware. And started with an empty new /home, sweet /home.

    What I did not do:
    Change any settings of my two WLANs or did anything else than in Kubuntu 16.04 or 18.04 before (as far as the settings in KDE Plasma are still the same).

    Following are some infos about hardware and other stuff:

    If I set the SSIDs to visible this error is gone and the automatic connection just works, as I said above…

    Well, I know hiding SSIDs is no major security feature, but I would like to be able to do it nonetheless - as I have done for the last two decades and the "approval" of the former Kubuntus, several other operating systems, mobile phones, TVs, etc… ;-)

    Any ideas how to fix this?
    Did I make a mistake or overlook something?

    PS: Other than the failing autoconnect to hidden SSIDs the wireless functionality of Kubuntu 20.04 works absolutely flawlessly. :-)

    Many consider it an insecurity feature. I would not be surprised if Kubunutu does not support it ootb for security and privacy reasons.

      Yes, you are right, of course - one could argue that it adds attention to people who will find it anyhow.
      But it did work in Kubuntu 18.04 (and KDE neon, when I tried it on the laptop some time ago) ootb - force of habit.

      OK, perhaps I should not waste my time with this and pick some "neutral" names for the two networks to not provoke the neighbours… :-D
