Description Eric Armbruster 2022-03-03 08:22:19 UTC

SUMMARY
Plasma nm prefers WPA2-PSK security type over WPA3-PSK security type when setting up a new connection to a network that offers connections of both security types.

STEPS TO REPRODUCE
1. Set up your home network to enable both WPA3 and WPA2.
2. Open the plasma nm applet and set up a new connection to this network


OBSERVED RESULT
After successful connection, go into details tab in the plasma nm applet and observe WPA2-PSK as security type.

When I remove the connection and set up a new connection again, this time via nmtui, the observed security type after connecting is WPA3-PSK.

This indicates to me the bug is not upstream, but in plasma-nm.

EXPECTED RESULT

Operating System: openSUSE Tumbleweed 20220227
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.2
Kernel Version: 5.16.11-1-default (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5700U with Radeon Graphics
Memory: 14.4 GiB of RAM
Graphics Processor: AMD RENOIR

I think I found the problem: https://invent.kde.org/frameworks/networkmanager-qt/-/blob/master/src/utils.cpp#L397

Would like to submit a MR for this.

Perhaps this was a bit premature, but will certainly try to look into it.
