Last night the machine was working fine. This morning, no internet access.
I'm working with a wired Ethernet connection.
I can ping the router, but not google.
I am able to access shared files on the machine from another computer through the wired network.
Other machines on the network can access the internet. It's only the Ubuntu box that can't get internet.
I can ping google by address but not by name.

It's my understanding that /etc/resolv.conf is for public nameservers only. It appears that yours has been modified to use a private nameserver ostensibly over a VPN. If you wish your Ubuntu box to obtain Domain Name Service normally to allow internet access, I suggest that you revert back to the default /etc/resolv.conf file which contains:
You can revert back to the default
/etc/resolv.conf
file by either restoring the original from a recent backup from before it was modified, or opening the file the link points to with the commandsudo gedit /etc/resolv.conf
and pasting the code from the default file above into it overwriting it's current content. You may want to save a copy of the current content beforehand as a backup somewhere you will be able to locate it if you find you need it.NOTE:
/etc/resolv.conf
is a symbolic link to the file/run/resolvconf/resolv.conf
so file based operations such as editing on /etc/resolv.conf will actually be carried out on/run/resolvconf/resolv.conf
To confirm that the link hasn't been erroneously modified run the command
ls -l /etc/resolv.conf
which should result in the output below.the arrow indicates it's a symlink.
For more information on resolvconf which modifies this file see the man page.
