Ethernet lacks a proper IP setup.

Attempted those commands and attached the outcomes below. Would you like me to include that the wireless dongle I'm using supports Realtek? Also, I've been removing it during these tests.
I just made a capital C in the controller, but it still didn’t display. Did I try again without it? The same issue appears at the 3.0.0 version in the screenshot.
I should have noted that Linux is case-sensitive. Your Intel i211 NIC works fine, but it still detects the cable as connected while reporting an IP issue—likely a NIC problem. I had a similar experience on a server motherboard. Do you have any NIC AIC models available for testing? You might also try turning off the NIC in the BIOS and then re-enabling it. (This could help if you're concerned about power issues.) As a last option, consider updating the BIOS. I’d only try this as a final step.
