Some routers/modems may have the WPS button disabled by default. You also may need to press the WPS button for a little longer on your wireless router/AP (5-7 seconds).
If you have already tried the WPS button setup and the LED on the range extender does not turn green, then try the WPS setup again by following the steps below:
Step 1: Wait for the LED on the DAP to blink amber. Press and hold the WPS button for 3 seconds on your wireless router/AP. (Some routers/AP's may require you to hold it a little longer)
NOTE: Make sure the WPS/Wi-Fi LED on your wireless router/AP is blinking after pushing the WPS button.
Step 2: Once confirmed the WPS/Wi-Fi light is blinking on your router, within one minute press and hold the WPS button on the Range Extender for 2-3 seconds. The LED should start to blink green. Once it makes connection with your router the LED will stop flashing and turn solid GREEN. (This may take up to 3 minutes)
