I'm a sitting duck over here too after the upgrade. The only thing in my network interfaces file is
auto lo
iface lo inet loopback
I can ping the router but that's it. I'm not getting any DNS resolve
Should I have auto eth0 in there too?

We'd like to see the actual reply to:Code:ping -c3 8.8.8.8Not usually; Network Manager should do the job quite well.Should I have auto eth0 in there too?

Do these settings come from the router; i.e. is Network Manager set for DHCP or are there custom settings that you've added?CONNECTIONS.AVAILABLE-CONNECTIONS[1]: 62893167-6aa4-3d7e-a6f4-423ca687cb5f | Wired connection 1

You are getting to the internet, but no names are resolved.ping -c3 8.8.8.8

Interesting.
BTW, I have upgraded to 17.10 and everything works as expected. I don't suspect a systemic issue or bug, so far.

No custom settings, DHCP is set to automatic.
I get a ? across my network icon. Wireless doesn't work either.
But I can get across my internal network OK
I rebooted the router for good measure.
the broadcast IP is internal, that should be my external IP.
Now it gets interesting.
I use PIA vpn. Just turned it on and I'm connected to the internet. Go figure.

Well this just keeps getting weirder for me.
I removed PIA and it didn't change anything. I removed the network connection via NM and added another.
I tried OpenDNS in the settings. Reboot, reboot, still no connection.
What's really strange is that I can open a Kubuntu Virtual Machine on the same laptop (System76 Kudo) and it will connect to the internet no problem.
VirtualBox using a bridged connection. Settings are identical to the main machine.
So something is blocking that network adapter mac address maybe?
I also have a vanilla Ubuntu installed on a virtual machine on my MacMini. Just testing the beta out. Guess what? No network connection today.
Totally different machine. I have no idea? But that one is easy. I can just remove it.
So in the meantime, I'll just put PIA back on and let it load at startup until I can sort it out.
