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?

    How did you try to change it? All you have told us is what didn't work.

  • I tried both via cli and via the gui in the right topcorner what worked, but after a reboot or shutdown, internet is lost because the changes i made to the wifi configuration are lost again

    the pi, the original file was there and the backup disappeared that is very unusual - what are you running? Raspbian? May 24, 2017 at 5:28
  • Yes raspbian pixal on pi3 . I already did an apt-get update and upgrade. I have no idea how this can happen. Seems like during startup it reloads the same settings from a previous period. Also my datetime and timestamp are 2 months back in time. Until i set the wifi and it loads the correct time from the internet.

I think you have installed an extra network manager. No problem. Create a /boot/wpa_supplicant.conf file instead of the /etc/wpa_supplicant/wpa_supplicant.conf file. and when you reboot you will see it changed.
