Make sure that your Ethernet cable is working and not damaged. And if there is an update, follow the onscreen instructions to update your Mac. You can check for updates by going to System Preferences > Software Update. Make sure that your Mac has the latest version of macOS. If you are having this problem, try the steps below in order until you have fixed your issue. On your Mac, you can use a wired connection, instead of Wi-Fi, by connecting your Ethernet cable between your router or modem and the Ethernet port (or your Ethernet adapter if your Mac does not have this port).

Likewise, you may experience that your Mac’s Ethernet ports may not be working and you may see that network status is saying “Cable Unplugged” while it is connected. Sometimes you may experience that your Wi-Fi connection is working properly, but still, you may not connect your Mac to the internet using Ethernet.
