    Something is wrong with the Ether network, or with the router, or with the Ethernet interface in the Mac. There's a very remote chance you can fix it this way, but I don't hold out much hope:

    If you think system corruption might be causing the problem, then you should reinstall OS X in place, after backing up all data.

    You wrote in your original post that you could get online via Wi-Fi. Also, if your theory is correct, you should be able to connect to the router when booted in Recovery mode.

    Actually, now that you mention it, that would be a good test.

     

    Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.

     

    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with networks that require any kind of authentication other than a WPA or WPA2 Personal password.

     

    From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. While in Recovery, you'll have no access to your saved bookmarks or passwords, so make a note of those before you begin, if they're needed for the test.

     

    Test. After testing, reboot as usual and post the results.
