(SOLVED) Ethernet wont connect mint 20.3

[AubsDaGoat305]

Hi all, first time trying Linux. When I install mint 20.3 cinnamon on a brand new build I have no WI-FI connections that show up (must be that I have no Wi-Fi adapter on my motherboard, no matter). So I try an Ethernet connection. When I plug in my Ethernet cable, nothing happens. There is a thread talking about installing a Realtek driver (viewtopic.php?t=335649) when I try these steps I get as far as being able to right click the file “src” but I don’t get an option that says “extract here” from the drop down menu. If I try to skip one step and try the command sudo ./autorun.sh in terminal from inside the file it says command not found. Am I missing something? Any help is appreciated!

Hi Larry, thank you for your reply. I followed your instructions and this is what I got back. I managed to get a wired connection for now via my iPhone and USB. I bought a Cat6 cable as well just to make sure it was not my ethernet cable itself that was faulty, since it was old.

Hello again. I followed these steps to solve the problem: I used the update manager to update to the latest kernel. I followed the steps in this thread - viewtopic.php?p=2098990 and afterwards my wired ethernet connection works like a charm.
