Cannot establish a powerline connection between FRITZ!Powerline adapters

The "Powerline" LED on at least one FRITZ!Powerline adapter is not lit and the powerline connection cannot be established. This also means that you cannot establish a network connection between the FRITZ!Powerline adapters.

Simply proceed as described below. After each measure, check whether the issue persists.

1 Using a button to load the factory settings

Incorrect settings in the powerline adapters can prevent the connection from being established. Therefore, load the factory settings of all FRITZ!Powerline adapters in order to delete all such settings:

2 Connecting FRITZ!Powerline adapters

In order to connect individual FRITZ!Powerline adapters or add additional FRITZ!Powerline adapters to an already existing powerline network, all of the adapters must use the same network password:

  1. Plug the FRITZ!Powerline adapter(s) into an electrical outlet.

    Note:When configuring the powerline adapters, plug them into adjacent sockets so that you can connect them without having to go a long distance. As soon as they have been connected to form a network, you can plug them into the electrical outlets you would like to operate them in.

  2. On the FRITZ!Powerline adapter that is to receive the network password, push the corresponding button to initiate the reception of the network password:
    • If you have a FRITZ!Powerline adapter with a button or buttons on the base of the device:
      • Push the "Security" button for one second.
    • The "Powerline" LED on the adapter flashes.
    • If you have a FRITZ!Powerline adapter with buttons on the front of the device:
      • Push the "Powerline(/Security)" button for one second.
    • The "Powerline(/Security)" LED on the adapter flashes.
  3. Within two minutes, push the corresponding button on the FRITZ!Powerline adapter that is to transmit its network password:
    • If you have a FRITZ!Powerline adapter with a button or buttons on the base of the device:
      • Push the "Security" button for one second.
    • If you have a FRITZ!Powerline adapter with buttons on the front of the device:
      • Push the "Powerline(/Security)" button for one second.
  4. Repeat steps 1 - 3 for all other FRITZ!Powerline adapters you would like to integrate into the powerline network.
    • The FRITZ!Powerline adapters connect automatically. Once the connection has been successfully established, depending on the model, either the "Powerline" LED or the "Powerline/Security" LEDs on both of the adapters remain lit. If you are using a FRITZ!Powerline 1240E that has both of these LEDS, then the "Powerline" LED remains lit.

3 Checking whether the FRITZ!Powerline adapters are working properly

  1. Plug the FRITZ!Powerline adapters into adjacent plugs of a power strip. Unplug all other devices from the power strip.
  2. Right after you plug them in, check whether the "Powerline" LEDs of all FRITZ!Powerline adapters light up.
    • If the issue no longer occurs, then the powerline connection was previously subject to interference, for example from high-frequency signals or electrical systems with damping effects. Normally one of the following measures can eliminate the cause of the interference:
          • Plug the FRITZ!Powerline adapters directly into a wall outlet instead of using extension cords or power strips.
          • Test them in different wall outlets in the same room as well as in different rooms.
          • Do not ever use FRITZ!Powerline adapters behind a device with surge protection (for example a power strip).
          • Reduce the distance between the adapters.
          • Avoid powerline connections on different electricity phases, fuse boxes and ground fault circuit interrupters (GFCI).
          • For testing purposes, unplug other appliances in order to identify and eliminate possible sources of interference.

            Note:Examples of frequent sources of interference are switched-mode power supplies, dimmers and halogen systems, refrigerators and freezers, dryers and washing machines, or electric pumps in use.

          • Lay cables that carry VDSL signals at least 10 cm away from electrical wiring and outlets.
            • If the powerline connection still cannot be established despite this, we cannot offer any further suggestions on how to optimize the powerline connection.
