[SOLVED] How do I reinstate default Network & Volume control icons on the Panel?

[torreydale]

You should still be able to view network connections via the Network Connections app located at Menu->Settings->Network Connections.

To get your wifi and volume indicators to return to the panel, try this:
    1) Menu->Settings->Panel
    2) Go to the Items tab
    3) Hit the + button located on the right
    4) Select Indicator Plugin
    5) Hit the +Add button

If my hunch is correct, your wifi and volume icons will reappear.
