My ISP doing some repairs on my broadband cable so my internet connection is dropping frequently, when my internet connection drops, Network Manager, shows that there are no interfaces. I have to restart network-manager using start and stop connections to get it working again.

Using Ubuntu with KDE 4

network manager has a dbus API and python has a dbus connector. seems like it's time for a script – RobotHumans Mar 5 '12 at 17:35
@aking1012 Hmm a python script to restart network-manager ? – HackToHell Mar 6 '12 at 3:52
Yep. Monitor nm through a dbus connection and if you can't get out restart the service. Simple enough, but kind of a patchwork solution – RobotHumans Mar 6 '12 at 4:13
