ControlCenter/Configuration/Packaging/Install software. In the search type in KPPP. It should come up, if it doesn't it is already installed. If it is installed do my previous post. It's there it's just hidden. When you click 'all apps' it will show up. It works everytime for me. You can also go to a terminal and type in "kppp" and see if it works. It's there if you set up your internet network during the install.
I know that you shouldn't log in as root, Proud, but why hide the other apps for a regular user. It shows 'all apps' including the system admin tools when you select the way I said above. I would recommend them being hidden when logged in as root. I have logged in as root once since I installed this OS. That was when I was getting ready to install NVIDIA drivers and got tired of typing in the password, it's strong ok.
Give it a try please.
