Check Your Cable

The ethernet wire is one of the first items to inspect. Examine for signs of damage, such as burn marks or twisting. If the cable appears to be damaged, replace it.

Check your ethernet connection after using a different cable. Otherwise, unplug and reattach the current cable several times. This is done to establish a secure and reliable connection between your Mac and a network device. You can also try inserting the current cable into a different computer or port to see if it is the source of the problem.

Ensure Settings Are Correct

Is your ethernet wire in good condition? The next step is to double-check your network settings. Make sure you’ve picked Ethernet rather than Wi-Fi. Incorrect settings could explain why you can’t connect to the internet over a wired connection no matter how hard you try.

Check your network settings as follows:

  • Begin by selecting the Apple menu from the home screen of your Mac.
  • Then, select System Preferences.
  • Then select Network.

Have you got a working cable and the necessary network settings? Now is the time to restart your Mac’s wired network interface. This method removes any random bugs or junk Memory that may have been interfering with your Mac’s ability to connect to the internet.

Here’s how to go about it:

  • To begin, open the Finder software on your Mac.
  • Choose Applications. Then select Utilities.
  • Locate and launch the Terminal application.
  • Then, enter the following command: sudo ifconfig en0 down. Then press the Enter key. (Note: en0 refers to the wired network interface.) Go to Apple Menu > About This Mac > System Preferences to check yours. Then, on the left sidebar, select Network. The name of the Ethernet will appear in the list on the right.)
  • If prompted, enter your password.
  • Then, enter the following command: sudo ifconfig en0 up. Then press the Enter key.

Restart your devices in the following order:

  • First, turn off your Mac.
  • Then, turn off your modem.
  • Wait around 30 seconds.
  • Reconnect your modem.
  • Wait for the modem to fully power on. Check to see sure all of the lights are turned on.
  • Finally, power on your MacBook.

  • To begin, make sure your ethernet wire is hooked into your Mac. Check to see if the modem is also operational.
  • Then, on your Mac, navigate to the Apple menu.
  • Choose System Preferences.
  • Then, select Network. A list of network services can be seen on the right side.

  • Return to the Apple menu > System Preferences > Network once your device has been turned back on.
  • Select the Add option. Click the dropdown option in the pop-up window. Select Ethernet. Then press the Create and Apply buttons.
  • Allow your Mac to connect to the internet automatically.

Update the Kernel Extension

If restarting and re-adding ethernet did not address the problem, it is time to investigate another software-related cause. Many Mac users reported that they suddenly couldn’t connect via ethernet. However, the problem did not affect Wi-Fi or other types of wireless connectivity.

Do you experience the same thing? Your Mac’s kernel version could be to blame. Apple suggests that you check what software is installed on your machine. Go to the Apple Menu, then About This Mac, then System Preferences. The kernel version that is causing the ethernet problem is 3.28.1. If you see that on your Mac, you must update to 3.28.2. 

Since you can still connect to Wi-Fi, you can fix this issue with a single Terminal command. Here’s how to do it:

  • Launch Finder.
  • Then, choose Applications. Then select Utilities.
  • Select the Terminal option.
  • Then use the following command: sudo softwareupdate -background. Press the Enter key.
  • The terminal should be closed. After that, restart your computer.
  • If no Wi-Fi network is available, proceed with the following procedures to upgrade your kernel version:
  • Begin by powering down your Mac.
  • Press and hold the Power button. Then, simultaneously press the Command and R keys.
  • The Apple logo will be displayed on the screen. Your Mac will enter Recovery Mode in a few seconds.
  • Please enter your password. This will bring up the macOS Utilities window.
  • Choose Disk Utility. Then, choose your drive. Your drive’s default name is Macintosh HD. However, if you moved or renamed it, you will see a new name.
  • If the drive name is grey, FileVault is protecting it. Choose File. Then, from the Disk Utility, select Unlock. Finally, type in your FileVault password.
  • Then, select File. Then, in Disk Utility, mount your drive by clicking Mount.
  • Disk Utility should be closed.
  • You’ll be returned to the macOS Utilities window. Look at the top menu bar and select Utilities this time. Select Terminal from the dropdown options.
  • Type this command as one line: rm -rf “/Volumes/Macintosh HD/System/Library/Extensions/AppleKextExcludeList.kext”. Then, hit Enter.  (Note: The drive is called “Macintosh HD.” If you’ve changed the name of your drive, change this.)
  • Leave Terminal.
  • Then, from the Apple menu, choose Restart.
  • Your ethernet connection should now be operational. Go to the internet.
  • After that, go to Finder > Applications > Utilities > Terminal.
  • Enter the following command: sudo softwareupdate -background. Enter your password. This procedure ensures that your Mac’s kernel has been updated to version 3.28.2.
