| Apr 9, 2021 at 10:10 | comment | added | jksoegaard | Please explain more about who provided this ethernet connection to you. Is it an ethernet port in the wall in your corporate office? In a dorm room? On a router from a consumer ISP? - For corporate and university settings it is common that additional authentication of computers is required, meaning that a certificate file needs to be installed on the computer before it can connect to the LAN. If you already have that installed on the Windows machine that explains why the Windows machine works and not this. Similarly some places require you to register MAC addresses of equipment in advance. | |

| Apr 7, 2021 at 8:18 | comment | added | Chrollolucifer | @GordonDavisson My WiFi and Ethernet are connected in same network. Subnet, Router and DNS Server are same except IP Address, Wifi has internet access while Ethernet hasn't. I change WiFi's IP to Ethernet's IP, Wifi still has internet access. I've tried to inactive WiFi, Ethernet still hasn't internet access. My iMac and Windows PC Ethernet are same network , only different on IP Address, but even i changed iMac's IP to Windows' IP, The iMac Ethernet still hasn't internet access. | |

| Apr 7, 2021 at 8:00 | comment | added | Chrollolucifer | @Monomeeth, yes i have, actually i am working on iMac that had been used by another person before me in my office, and then i asked him "was the ethernet working when you were working on this iMac ?" he said "yes, but needed more effort that i don't remember anymore". I assume it stopped working when first time i used it and the OS was Catalina. And then i did above approaches until i decided to upgrade it to Big Sur and then did above approaches again. You can't, the current cable and previous cable isn't plugged into the same port. But i've connected to previous port but still not working. | |

Does it work if you leave the Ethernet connected & on, but turn off WiFi? Also, does the Windows PC get the same address prefix, subnet, etc when it's connected & working? | |

| Apr 7, 2021 at 6:21 | comment | added | Monomeeth♦ | Have you previously been able to use ethernet on this Mac? If so, when did it stop working? That is, did it stop working at the same time something else changed (e.g. upgrade to macOS Big Sur, change in router, etc)? Also, when you say, "I plugged in my cable on Windows PC and it worked beautifully!", can we assume it's the same ethernet cable plugged into the same port on the router? | |
