I believe that I may have come up with a work-around for the "Insufficient Privileges" error.
I inadvertently deleted my top panel and had to re-create it. When I added the "Indicator Applet Session", my NetworkManager applet re- appeared. I was then able to go into the Mobile Broadband tab and edit my T-Mobile connection without even being presented with the password dialog. I have re-booted a couple of times, and the applet is still there and so is my broadband connection -- in fact, I am using it as I write this. Perhaps this will help the rest of you, too. -- NetworkManager won't allow user to edit settings of Mobile Broadband connection https://bugs.launchpad.net/bugs/456261 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
