ethernet cable not showing up in network adaptors

i have been using a linksys wireless WiFi usb port adapter to connect to the internet but wanted to recently connect to internet manually. When i plug in the ethernet cable, absolutly nothing happens. nothing pops up in bottom right of screen, and cant find local device. when i go to device manager network adapters is no where to be seen either. i have plugged ethernet cable into laptop and imediatly it worked, so its not the cable. i have searched all over the web but nobody else seems to be having the same problem. let me know if you need any information or screen shoots.

Hi welcome to the forum

go to bios and see if it is enabled

can you give me directions? dont know much here /:

start computer and start tapping F2,or F1 or delete key to get to bios. could also be F10. then look in there for lan. it could say on the screen what key to press to get to setup.

i have a gaming g series msi computer, so the button was del. when i got in the menu there was a motherboard overlay and it showed that there was a eithernet port but i didnt know how to restart or do anything with it

i am not familiar with that so could you take a picture of your bios?

its called click bios 4

here is a pic

that isnt my system though, just one i got from google

dont have a answer?
