Wi-Fi is missing after upgraded to Windows 10

I just upgraded to Windows 10. Laptop Model: Dell Inspiron 14.  It requires new drivers to install. I've google about it and the current solution is using a software DRIVE THE LIFE to help download and install suitable drivers for Windows 10. Then, after the Wi-Fi driver has been reinstall. Wi-Fi is missing from my laptop. It's disappear from my settings (network & internet). I checked the drivers, it stated it is working properly. I tried different ways that have been shared in the internet and I still can't solve this. I have no clue what happened to my laptop.
