All you have to do is:
1. Unplug the modem power.
2. Shut down the Mac. Apple menu (the Apple logo in the upper left corner) -> Shut Down. Confirm the desire to shut down and wait for the screen to go black.
3. Connect the ethernet wire directly from your Mac to the modem. Don't use the Netgear at all.
4. Connect the power cable to the modem.
5. Wait for the modem to start showing it has internet connectivity. Ask your internet provider what light that would be for your modem model, if you don't know.
6. Power up the computer.
7. Verify internet connectivity in Apple menu -> System Preferences -> Network -> Click on the popup menu Show at the top below the menu for Location "Built-in-ethernet". See the image below:
8. If your IP address is a 10, 169, or 192 prefix you are still not connected to the internet. Let us know if this is the case.
Otherwise, you should be connected to the internet, and should be able to test the internet connection and see if there is any difference.
