Package: plasma-nm
Version: 4:6.7.4-2+b1
Severity: normal
X-Debbugs-Cc: none

Given Update to new libkf and systemd on 2026-10-22 (the update include libkf, 
plasma-nm, network-manger, systemd, last working state was 2026-10-20)
Given Password is stored in kwalled and/or in network-manger config files or 
entered manuell.

When try connect to wlan
And apply password
Then the connection fails
And message "connection deactivated" appears
And message "no password set" appears

Comments
- try it on 2 system which were working before update
- the behaviour was observed on wlan via wpa_supplicant and iwd
- the behaviour was observed when using plasma-nm or nmcli
- the behaviour was observer also with non encrypten wlan
- all wlans of environment are listed, but 5GHZ is listed as 2.4GHZ in nmcli
