How to enable network manager in KDE?

[Yuri]

How do I launch network manager that allows to visually manage WiFi and 
LAN connections?
I have FreeBSD on a laptop and I have to establish WiFi connections 
manually -- it's very inconvenient.

In Kubuntu this problem is solved and WiFi management is very easy. It's 
the same Looking for the same in FreeBSD.

Also how to make ifconfig display very long SSID strings?
