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

MSI Z270-A PRO motherboard
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.

If you cannot access the internet with this PC

You will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.
If you do not have another PC
Do you have a phone connected to the internet - can you photograph the result and post the image in a reply
Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the information above those entries

For Windows 8 or Windows 10

To open a Cmd Prompt or an Administrator Cmd prompt from the Desktop.
Use Windows + X Keys together and choose Command Prompt (Admin) from the list.

then

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
