My wifi credentials have been changed but i can't change my raspi wifi connection. I can change it via the gui, but after a reboot, the old settings appear again in the wpa_supplicant.conf file.
Tried to change if via nano and cli but after rebooting, the old settings are appearing again.
I also tried to copy the wpa_supplicant.conf file to wpa_supplicant.conf_old file but after rebooting the pi, the original file was there and the backup disappeared.
Can somebody please help me locating the real wifi settings file so my wpa_supplicant.conf is not rewritten again with the old settings?
