--- Comment #23 from Lamarque V. Souza <lamarque at kde.org> ---
I am the Network Management maintainer in KDE, I use NetworkManager 0.9 and do
not have this problem. Networkstatus works as expected here.

Is everybody with this problem using only Arch? Does Arch stop NetworkManager
when suspend to disk?

qdbus org.kde.kded /modules/networkstatus
org.kde.Solid.Networking.Client.Status == 1 means some program has marked the
system as Unconnected (offline), usually it is networkstatus that does that.

Restarting kded4 helps with this problem  because the networkstatus module
tries to detect the network status when kded4 starts.

Networkstatus has three backends: NetworkManager, Wicd and NTrack. NTrack is
the fallback backend (if it is was compiled) and as so it is used only when
neither NetworkManger nor Wicd are running. I can say NTrack is the most
problematic of those three. If you have NTrack installed I suggest that you
recompile kde-runtime after uninstalling NTrack. There is no other way to
disable the NTrack backend. Enabling NTrack is a decision of the distribution,
in my case Gentoo does not enable NTrack and I do not need it anyway since I
use NetworkManager.

Do do not mess with the configuration in systemsettings -> Information Sources.
Use the correct backend (usually NetworkManager 0.9 or Wicd) and that is it. If
you change from NM to Wicd (or vice-versa) change the backend in Information
Source or your network support is going to be unstable or even not work at all.
Never run too network management software (NM, Wicd, ifplugd, etc) at the same
time, choose only one and disable all the others.
