Unify Your Wi-Fi Networks via WPS

Copy SSID and password from your router via WPS to create one unified Wi-Fi network throughout your home.

Note: If your router doesn’t have a WPS button, manually change the extender’s Wi-Fi settings via the tpPLC app, tpPLC Utility, or web interface.

  1. Plug in the extender in the same room as your router. Wait until the extender’s Wi-Fi LED turns on.
  2. Press your router’s WPS button. Within 2 minutes, press the extender’s Wi-Fi button for 1 second. The extender’s Wi-Fi LED starts blinking. When it stays on, Wi-Fi settings are copied.
    Note: If Wi-Fi settings are not copied within 2 minutes, manually change the extender’s Wi-Fi settings.
  3. Relocate the extender and enjoy the internet using your router’s SSID and password.

Create a Secure Powerline Network by Pairing

Note: You can only pair two devices at a time. We recommend that you plug in the powerline devices near each other when pairing.
Pair the Powerline Devices

  1. Press the Pair button on the adapter for 1 second. Its Power LED starts blinking.
    Note: If the Power LED does not blink, press the Pair button again.

Sync Wi-Fi Settings to More Extenders

If you have more extenders, simply plug in and pair each one with the existing adapter to join the network. Then the Wi-Fi settings will automatically sync from the existing extender to the new ones.
