Q: If the Ethernet connection on your Mac stopped working recently?

This solution does not work for me.   Any other ideas?  It's NOT my cable.  I did everything precisely as specified.

iMac (21.5-inch Mid 2010), OS X Yosemite (10.10.1)

    Reinstall OS X Without Erasing the Drive

     

           Be sure to backup before proceeding.

     

    1. Restart the computer and after the chime hold down the Command and R keys until the Utility Menu appears.
    2. Choose Disk Utility from the Utility Menu and click on the Continue button.
    3. After Disk Utility loads select the indented (usually, Macintosh HD) entry from the side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button.
    4. When the process finishes, quit Disk Utility and return to the Utility Menu.
    5. Select Reinstall OS X and click on the Continue button.
