Wi-Fi icon in the taskbar gone

[T1125P]

Hello, this one worked:

  "If it is not there, do the following to put it back on the panel:
While in Items tab, click the "+" to add a new item
Find "Indicator Plugin" on the list that pops up and click to highlight it; then
Click the "Add" button; then "Close" button
It will now be at bottom of Items list
If you want to change its position on the panel, use arrow buttons
Click "Close" when done and hopefully the wireless icon is back again."

Oh one more thing, is there a way to bring back the classic start menu and delete Whisker?

Thanks.
