I use opensuse krypton, plasma-nm 5.11.90git.20171029T033943~7553bbf9-15.1 In "wi-fi security" tab I select "wpa/wpa2 personal" and non-encrypted password, but kcm ignores my setting and sets encrypted password.
I cannot reproduce this problem. It saves whatever I choose and when I open the connection again, then it's correct.
I just noticed that the problem described here happens only when kwallet is disabled.
