SUMMARY The networking applet seems to generate non-compliant QR codes for WPA3 networks. STEPS TO REPRODUCE 1. Connect to a WPA3 Personal network 2. Open the Networks applet, click 'share' on the WPA3 network 3. Scan the QR code with another device (in this case it was a Sony Xperia 5ii running Android 12) OBSERVED RESULT the scanning device fails to recognise the QR code. (In the case of the Android 12 Sony this was a message saying 'this QR code is not supported' EXPECTED RESULT The scanning device connects to the WPA3 network SOFTWARE/OS VERSIONS Linux/KDE Plasma: fedora 43 kernel 6.17.12-300.fc43.x86_64 KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 ADDITIONAL INFORMATION Inspecting the QR code text, the 'T' field is 'T:SAE;' (the redacted QR code contents are 'WIFI:S:xxx;T:SAE;P:xxx;;'). The URI format for WPA3 is described in the wpa3 spec https://www.wi-fi.org/system/files/WPA3%20Specification%20v3.1.pdf section 7.3, and SAE doesn't seem to be a valid content for the T field. This behaviour seems to have been introduced in https://invent.kde.org/plasma/plasma-nm/-/commit/764cb342ea1b95487a7a065ae93f2779b91680a3 , and it seems that the generated QR code never got scanned when testing.
A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-nm/-/merge_requests/503

Use correct URL for QR codes for WPA3 networks The URL format as described at https://www.wi-fi.org/system/files/WPA3%20Specification%20v3.1.pdf (7.3) is that the type should be "WPA" for password based authentication. The same paragraph explicitly mentions SAE later so the spec must be up-to-date. M +1 -3 libs/handler.cpp https://invent.kde.org/plasma/plasma-nm/-/commit/7f3434814074cc85b9e09d5134c45c4437efb74a
