Cannot show internet connection on taskbar windows 10

Hello,

I can connect to internet just fine. But after I installed Malwarebytes and scanned then restarted my computer once. the wifi connection icon has disappeared from the taskbar.

I tried to go switched from off to on in notifications & actions but it won't let me switch to turn on to show the icon...

(I can switch ON for clock, volume, Power, Input Indicator, and Action Center but the switch of Network and Location is in gray color and won't let me switch to On.)

Please help! Thank you so much.
