Intermittently I can't connect to the mobile network (openSuSE 12.3, KDE). When the NetworkManager applet is triggered it says networking active, mobile connection is not checked. So I click on mobile connection and thus get the check-mark. But the icon with the name of my provider doesn't come, nor can I activate the connection.

"systemctl status NetworkManager.service" is all green and running. Same machine and linux mint can connect.

How can I find out what is the problem? (No luck in /var/log/boot and /var/log/messages). Thanks for any pointers.

<edit> Gaaah. Found it. I ran an update prior to the problem -- and in the course of applying the patches or what somehow lost the entry for my provider in NetworkManager. I simply re-entered my access data and erverything works as it should. Thanks for every single member of LQ who had a look and tried to help </edit>
