I installed a fresh Ubuntu beside Windows 10. In Windows, I have Internet access by ethernet. In Ubuntu, I can see a Wired Connection 1, but without internet access. I am behind a local network.
Ubuntu 16.04.6 LTS
Here are the outcomes of some commands:
sudo gedit /etc/NetworkManager/NetworkManager.conf
sudo gedit /etc/network/interfaces
I have tried to set interfaces to:
auto enp0s31f6
iface enp0s31f6 inet auto
and then restart the network manager/ reboot, but it didn't work. If fact, as soon as the restart occured, the enp0s31f6 interface was not shown in ifconfig. Any help is appreciated, thanks.
EDIT: Normal internet connection, via USB tethering
Tried sudo apt-get update, sudo apt-get upgrade, still NO internet connection via ETHERNET
EDIT2:
Output for: sudo dhclient -d enp0s31f6
