After switching to systemd, I started to use NetworkManager.service, I got connected to WIFI automatically at boot, but I got the following message when I run nmcli con:

** (process:4433): WARNING **: Could not initialize NMClient /org/freedesktop/NetworkManager: Method "GetAll" with signature "s" on interface "org.freedesktop.DBus.Properties" doesn't exist

Error: nmcli (0.9.6.4) and NetworkManager (unknown) versions don't match. Force execution using --nocheck, but the results are unpredictable.

And from systemctl:

NetworkManager.service                              loaded active running       Network Manager

Now if I restart NetworkManager.service, it works. Why is that?

“nmcli (0.9.6.4) and NetworkManager (unknown) versions don't match”. Have you tried fixing that? Where do nmcli and NetworkManager come from? – Gilles Nov 28 '12 at 0:19
@Gilles they both belong to networkmanager 0.9.6.4-1, official repository of Arch, and it looks like a DBUS problem – warl0ck Nov 28 '12 at 0:21
I have a similar anomaly. NetworkManager will drop the wireless connection after a while and NetworkManger restart is required. Arch Linux and Gnome 3.6 on systemd – keepitsimpleengineer Nov 30 '12 at 22:21
After deprecating Gnome 3.6 and fresh install of ArchLinux/Xfce 4.1, the problem still occurs. In addition, after restart of NetworkManager.service, the NetworkManger applet disappears. – keepitsimpleengineer Dec 8 '12 at 19:16
@keepitsimpleengineer i don't know, but the problem disappeared now ... and I don't use a panel – warl0ck Dec 9 '12 at 0:35

This is a known issue and several bug reports have been submitted.

There is also a workaround for ubuntu, but I don't think it will work for Arch users because they no longer use init scripts. I bet their fix can be ported but I don't know enough about systemd to do it.

Here is a solution from the Fedora forums that looks like it works:

  • Right-click on the NetworkManager applet.
  • Edit Connections.
  • Click the Wireless tab (if that's what you're using)
  • Select your connection and click the Edit button
  • Go to the IPv4 Settings tab
  • Click the Routes button
  • check "Use this connection only for resources on its network."
  • Press OK
  • Uncheck "Available to all users"
  • Press Save
