Computer won't connect via ethernet

So I can connect to the internet through wifi, but when I try to use an ethernet cable it can't identify it. I know the cable works, I plugged it into my laptop and got ethernet connection on that. When I run troubleshooting it says "Ethernet does not have valid IP configuration."

Not sure if system specs will help but here they are

It has an integrated Realtek RTL8111H gigabit ethernet device.
The listed Windows 10 64-bit driver for it is version 10.018.0526.2017

Go into the Device Manager and expand the Network Adapters heading.
Double-click the ethernet device to open its properties window.
In the "General" tab, does it say the device is working properly?
In the "Driver" tab, what's the driver version and driver date?

in addition to Franks question would you also post an ipconfig /all when the lan cable is connected
ipconfig /all

We would like to see the results from an ipconfig /all - Please post back the results in a reply here.
