FRITZ!Powerline 1220E Service

Powerline connection drops frequently

The powerline connection between two or more FRITZ!Powerline adapters drops frequently. After the connection drops, it is either automatically re-established, or it might be necessary to briefly unplug one of the powerline adapters.

1 Installing the latest firmware for FRITZ!Powerline

2 Checking whether the FRITZ!Powerline adapters are working properly

Test the FRITZ!Powerline-Adapter while it is plugged into a power strip to rule out technical defects:

  1. Plug the FRITZ!Powerline adapters into adjacent plugs of a power strip. Unplug all other devices from the power strip.
  2. Use a network cable to connect a FRITZ!Powerline-Adapter to your router (for example a FRITZ!Box).
  3. Use a network cable to connect the other FRITZ!Powerline adapter to a network device (for example a computer, set-top box).

    Note:If you are using a FRITZ!Powerline adapter with wireless capabilities, you can also connect a wireless device (for example a smartphone) instead.

  4. Check whether the error also occurs when you perform this test.

3 Avoiding external sources of interference

Often external factors that disrupt the powerline communication over your house's electrical wiring can cause connections to drop. The following tips provide advice on how to eliminate such sources of interference:

  1. Do not ever use FRITZ!Powerline adapters behind a device (for example a power strip) with surge protection.
  2. If possible, only plug the FRITZ!Powerline adapters directly into wall outlets instead of using extension cords or power strips.
  3. Plug the FRITZ!Powerline adapters into different wall outlets to test their performance.
  4. Avoid powerline connections on different phases, fuse boxes, and ground fault circuit interrupters (GFCI).
  5. For testing purposes, unplug other appliances in order to identify and eliminate possible sources of interference.

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

  6. Lay cables that carry VDSL signals at least 10 cm away from electrical wiring and outlets.
  7. Reduce the distance between the adapters.
