pidgin waiting for network connection solved!

Open the terminal

Apllication -> accesories -> terminal

and type

gksudo gedit /etc/dbus-1/system.d/NetworkManager.conf

Then you replace the

allow send_interface="org.freedesktop.NetworkManager"

with

deny send_interface="org.freedesktop.NetworkManager"

(there are three it the text). Then save the changes and reboot. This will not permit firefox (or pidgin) to communicate with network manager and the state will be always online in firefox...
