How do I set up the Netgear EX6120 range extender for the first time?

To set up the EX6120, first place it in the same room as your WiFi router and plug it into an electrical outlet. Wait for the Power LED to turn green. Then connect to your existing WiFi network using either WPS (by pressing the WPS button on both the extender and router within two minutes) or web browser setup by visiting www.mywifiext.net. Follow the on-screen prompts to complete the setup process.
