I would like to modify the
wpa_supplicant.conf file. However if I do it, the file sets itself back to its previous version (even if I modify the file with one single character), and I have no idea where that sort of backup is stored nor if what I'm doing wrong.
I have tried to modify the file by copying it to a W7 PC and using notepad++, also with an SSH app with root rights granted. Same result. (have done the
chown wifi:wifi thing too)
The system is a LineageOS with Android 7.1.2.
Disable wi-fi →modify file → re-enable wi-fi and also reverse.
