Re: Network manager completely without data.

Are you talking about Network Manager or connman-gtk?
I have had a problem with connman-gtk being blank apart from the 'Settings' button. The applet also shows that it is not connected to the network, however, it is connected.
I found a solution on the Obarun forum that works for me at least:
https://forum.obarun.org/d/1832-connman-gtk-shows-blank/56
I just inserted the line
<allow send_interface="net.connman.Manager"/>
rebooted, and it is back to normal behaviour.
