Plasma-nm 5.6.4 reports WPA-PSK instead of WPA2-PSK

I have a SITECOM 300N wifi modem router.
Security settings: Authentication type: WPA2PSK, Encryption: AES.

OpenSUSE Leap 42.1 on two different PCs; plasma-nm applet reports “Protection type: WPA-PSK” instead of WPA2-PSK.
On the same two PCs I have installed also OpenSUSE 13.1 (KDE4); in that case, the nm applet reports WPA2-PSK.

If I run “iwlist wlan0 scan” (on the Leap 42.1) I get:

IEEE 802.11i/WPA2 Version 1
Group Cipher : CCMP
Pairwise Ciphers (1) : CCMP
Authentication Suites (1) : PSK

So, it seems that the problem is in plasma-nm 5.6.4 only.

As far as I know, NetworkManager does not distinguish between WPA-PSK and WPA2-PSK. That is to say, the configuration settings are neutral between WPA and WPA2.

After a recent update to Plasma 5.7.3, KDE Frameworks 5.24.0, Qt 5.7.0, now the plasma network manager applet reports WPA2-PSK.

That was 365704 – Not right security type. Shows WPA-PSK when it should be WPA2-PSK, fixed in 5.7.3.

Btw, the reporter mentions:

It should be WPA2-PSK. Kde4 shows it right.

But “KDE4” shows it wrong on my 13.2 system too.
Plasma-nm 5.7.3 does show it right now though (on the same system)…

Evidently, this bug has appeared since KDE4 for openSUSE 13.2.
In my case, with KDE4 for openSUSE 13.1 I don’t have this problem.

openSUSE 13.1 still used the old (and deprecated/unmaintained) plasmoid-networkmanagement.
plasma-nm (which replaced plasmoid-networkmanagement in 13.2) is included, but not installed by default (because it was brand new and not completely finished yet at the time of 13.1’s release).
