How do I set up the Netgear AC1900 Range Extender if my router has a WPS button?

First, attach the antennas by removing the caps and turning them clockwise to tighten, then place the extender close to your router and plug it in. Press the WPS button on the extender until the LEDs blink green, then press the WPS button on your router within two minutes. After a few seconds, the 2.4 GHz Link Rate LED should light green, indicating a successful connection.
