Make sure:

• The router is WPS certified. If it is, the logo would be shown on the router or on its user manual. Check with the manufacturer of the router for details.
  (If the router is not WPS certified, connect the speakers to the Wi-Fi network following the steps for “Connect to a non-WPS router”.)
• The router is powered on and is working properly.
• The speakers are powered on, and the LED indicator on the back of the speaker blinks in green slowly.
  Note: The on/off button is on the back of the speaker.
