Resolved!
Hi all,suddenly my Ethernet stopped working. It is not connected with Windows 11 since it worked on it pretty fine. Stopped working at the beginning of the month.      I've tried everything I could found on internet. 1) Windows Update - everything is up to date 2) Diagnose problem on Ethernet - it says that my cable is broken. Please note that I've tested the same cable on MacBook Air and it's working without any problems. 3) Changed Duplex in settings4) Reset IP config5) Reset modem/router Also tried other cable (which is working) putting directly into the modem but Ethernet is still not working. Here is what I get when pinging the 127.0.0.1 without any internet connection (ethernet cable is plugged in). [IMAGE]
