I have changed the settings of /etc/network/interfaces
but with this action my internet doesn't work anymore.
Now I want to change it back but I can't find the default settings.
If you have the default setting, can you place them here please?
For my Raspberry Pi 3B model it was
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
