Wi-Fi icon isn't visible; but connection is fine.
The Wi-Fi symbol/icon on the upper-left area of the top bar does not appear, even though I am already connected to a Wi-Fi network.
There is nothing wrong with the Wi-Fi connection since I can still browse the Internet and go online.
There's no longer any way for me to know the strength of a Wi-Fi signal since the icon isn't visible.
