nm-applet missing from task-bar problem on 14.04.1

[Aere Greenway]

All:

Now that Lubuntu 14.04.1 is available, I upgraded a Lubuntu 13.10 system 
to 14.04.  Unfortunately, the problem where nm-applet is missing from 
the task-bar is still a problem when upgrading such a system.

Does the system need to be installed from a newly downloaded and burned 
CD in order to fix the problem?
