Windows 10: Experiencing problems with connecting via Ethernet

My computer has experienced a problem where when I plug in the Ethernet cable and connect to the network, it fails to connect to the internet says it is an "Undefined Network" and can't connect to the Internet. When I run a diagnosis it finds that Ethernet doesn't have a valid IP configuration.
