Try installing an app called "WiFi manager" from the play store. If that doesn't fix it, a factory reset should, and as a last resort, check your wifi antenna. If all else fails, it must be at the chip level, which requires replacement of the motherboard. Hope this helps!

After installing the apk version of the software you've mention, I've clicked on the "turn on wifi" but its not working, the wifi button(in where i scroll down the screen) is still dark yellowish color(just like when you turn it on, it takes time before it fully turn yellow, but in my case it automatically turn off before it turn yellow), im now going to try the factory reset method, wish me good luck.
Btw, this is the first time using this website, thanks for fast responds:)
Your welcome. We always try to provide the best answers as fast as possible. If the factory reset doesn't fix it there is a good chance it's just a loose wifi antenna.
Apparently I still cant turn on the wifi after formatting, is this consider as hardware failure?
Possibly. It is very likely now that the wifi antenna is loose. Especially if you dropped it recently. Use the guide below to check it. It's the blue cable on the left of the phone. Samsung Galaxy Note 3 Motherboard Replacement

Open the phone app and dial the 2nd and 3rd to last codes and find any wifi related options.
