Using network manager (nm-applet) in KDE4

As of now knetworkmanager is not available for KDE4, and those of us using NetworkManager are going to have to settle with gnome's version of the network manager applet: nm-applet

First of you need to install networkmanager, read more on that here.

Once it's installed you need to set it up to run as a daemon, i.e. add it to /etc/rc.conf, and remove network:

DAEMONS=(syslog-ng networkmanager netfs crond alsa hal fam kdm)

Furthermore you have to exclude the interfaces you intend to use with networkmanager (also in /etc/rc.conf e.g.:

INTERFACES=(!eth0 !wlan0)

When that's done you need to install gnome-network-manager

# pacman -S gnome-network-manager

Then add yourself to the network group:

# usermod -g network your_username

And that should do it, you can now run nm-applet as a normal user, and switch between wireless and wired network without modifying rc.conf every time.
