My Wi-Fi direct is there, but it's not really active.

Hi,
My current phone is Samsung Galaxy Grand Duos GT-I9082L, I'm using Glade Rom right now. My Wi-Fi is there, but it's not really active. It doesn't even shows when I'm about to choose the option on Share Via. Is there anyway I can activate it or use a third-party app without the QR Scan Code? Since most of people nowadays don't use QR Code Scanner anymore. Thank you! :fingers-crossed:
