Anyways, one major feature I missed badly was the network-manager for KDE which apparently was missing in the default KDE4 setup. Here, let me show you how to install and get the network manager running.
1. Fire up your terminal and install kmix and network-manager for kde via apt.
Note, the network-manager package is a kde3 release which still works well in KDE4.
$ apt-get intall network-manager-kde
2.To run network-manager-kde, simply run this via terminal or using Alt + F2
3. To make sure kmix and knetworkmanager launch at startup, simply create a new Autorun file as follows (use your favorite text editor)
4. Add these following lines into it and save the file.
kmix; dcop kmix kmix-mainwindow;#1 hide
5. Setup the required permissions
6. Great you are done now. knetworkmanager should appear in your taskbar on startup.
