ive looked through several of posts here on related issues and the attempts ive made all seem to lead to the same result, that eth0 is not configured or discoverable.
i have a new 17.04 server, on a laptop which had successful wifi connection. wifi light wont come on. when i ping google, it says 'name or service not known'. have no wired access to connect to until tomorrow. i do have a live usb of the installer available to boot into recovery mode if that would help.
some results so far;
sudo ifup eth0
results;
internet systems consortorium DHCP client 4.3.5.

I suggest that you edit the file
/etc/network/interfaces
to replace the eth0 entry with wlp3s0 and add the SSID and encryption details, like this:So that you can ssh and ftp into it, I actually recommend a static address, not DHCP, however, let's get connected first and then proceed.
Reboot and tell us if you are connected:
EDIT:
If you wish to use ethernet as you indicated in your comments, then the sequence is:
Reboot.
