My ethernet connection inexplicably stopped working today. Already tried restarting the computer, replugging in the ethernet cable, doing a network reset in the Network and Internet settings, and disabling and re-enabling the Intel(R) Ethernet Connection (2) I1219-V device. Wi-fi works totally fine. My ethernet cable seems to no longer be detected for some odd reason. I haven't tried another cable yet, but it's such a pain in the ass to switch out the ethernet cable in my setup I want to try everything else first. This ethernet cable has worked fine for months.

what is on the other side of the ethernet cable ?
a router or a switch i suppose ? did you tried to plug the cable in another port ?

can you follow the cable and make sure it's not damaged at any point ? are both ends in good physical shape ?

on your PC, do you see the little amber and/or green lights near the ethernet port when you plug the cable ?

the probleam can also come from your OS
into "search"type ncpa.cpl . check if your ethernet adapter is not disabled. to enable it , select and right clic to it

there is also a command to use in order to reset the network stack completely :
open a command prompt as admin
type this : netsh winsock reset
wait a bit, it should ask you to reboot the computer. test your ethernet again
