After a long long hiatus, I'm trying to finally get back a bit into #KDE / #KDEPlasma development a bit.
Started by tackling with a minor nuisance I had with @kasts, which didn't display the URL of a link so far when hovering it.
Once https://invent.kde.org/multimedia/kasts/-/merge_requests/186 is merged, that should be a thing of the past.
This implementation is 90% blatantly copied from @neochat - that's the power of #OpenSource 😊
In the taskbar, by the clock, click on a WiFi of your choice and enter you password.
For example, mine was called 01_localhost and the password was Hi_0007
Go to System Settings
Go to Wi-Fi & Networking
Select (highlight) you listed Wi-Fi
On the General Information tab, check All user may connect to this network. Changed Metered to NO. On the Wi-Fi tab, change MTU to 1408. On Wi-Fi Security tab, change to WPA3 Personal. On the IPv6 tab, disable. Now click, Apply.
1st, notice you can NOT click on the export selected connection.
2nd, if you reboot, you will NOT be connected. Notice in System Settings (KDE) to connect.
3rd, if you click the + and manually add the Wi-Fi, still no option to connect.
4th, if you connect using the icon in your taskbar, by the clock (again), you will connect and a new copy of your Wi-Fi will be listed in System Setting each time you do this (after reboot). - You never reboot with a working connection and need to enter your password each time.
I have repeated this bug on both an upgrade from v39 to v40 and later on a fresh installation of v40 Fedora KDE Spin and Ultramarine Linux (both distros).
It also decided to try, Universal Blue, Aurora, an immutable distro, also Fedora KDE Spin based, with the same results (bug). I configured the network during setup (during the installation processes).
