Why cannot I find HiFi Direct in the Samsung Tab 2 Android 4.1.4 and disable WiFi Direct?

[AC Question]

Hi, there,

I've a strange experience. I use a Samsung Galaxy Tab 2 with Android 4.1.4. Until recently I was connecting with WiFi smoothly. For a week now WiFi D is enabled. Strange, that is inexplicable. I did not enable WiFi D. Naturally I cannot use WiFi. The strange thing now is that I cannot find WiFi D anywhere in the "Settings", not in "WiFi and Networking" or in "More". My cellphone shows WiFi D at the bottom of the screen in the WiFi menu, but not the tab. Can anyone help?

Thank you.
