Taskbar invisible

[trounces]

I solved it based upon a solution found here: xfce4-Panel doesn't appear after booting - #8 by trounces

@trounces

Go to System Tools > Session and Startup > Application Autostart > Add+

Name: Start taskbar
Command: xfce4-panel
Trigger: on login

Reboot the machine and taskbar appears automatically again with all the icons including network icon which did not appear when I manually started the taskbar later on.
