Here is a link to the ethernet driver for your motherboard.
What happens when you plug in the ethernet into your pc?
Can you run an ipconfig/all via command prompt and post it for review.
Disable the wireless first, then plug in the ethernet.
Now load up command prompt (can find it via a windows search)
Type ipconfig/all and hit enter into command prompt.
Once its done, right click the top of command prompt where it says "Command Prompt"
Right click > Edit > Select all
Then - Right click the same area again at the top > Edit > Copy
Then open notepad and right click and paste.
Save the document as a txt file and turn your wireless back on and remove your ethernet.
Now post the txt file for review.
This is a start to fixing your problem.
