The wifi button is not going on

found this:

Internal SD Memory the Path /data/misc/wifi/ the File named wpa_supplicant.conf is having issue.

Not going to guess what what was done on your side only that wifi cannot read that file so it just shuts off.

you need root to view this file, I suggest renaming it, reboot then enable wifi again and it will create a new one.

you will lose all saved passwords from the beginning of time but will be able to use wifi again.
