Slow data transmission in FRITZ!Powerline network

The throughput of the network connection between your FRITZ!Powerline adapters are very low.

This may lead to the following:

  • picture and sound loss when viewing IP TV.
  • delay when playing online games.
  • choppy playback during simultaneous video streaming

1 Preparations

2 Checking whether the FRITZ!Powerline adapters are working properly

Setting up FRITZ!Powerline adapters for testing

  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 one of the FRITZ!Powerline adapters to a computer on which the FRITZ!Powerline software is installed.
  3. Create a flow of data over the powerline network by copying files or establishing an Internet connection, for example.

Determining the throughput

  1. Start the FRITZ!Powerline software.
  2. Move the mouse pointer over the icon of the FRITZ!Powerline adapter that is not connected to the computer with the network cable.
    • An info window appears (see fig.).

      Fig.: Displaying the throughput

  3. Check the throughput displayed for "Send" and "Receive".

If one of the throughputs displayed is at least 250 Mbit/s, then your FRITZ!Powerline adapters are working properly.

Note:The data rate displayed for FRITZ!Powerline is the so-called gross data rate. The net data rate determines the speed at which user data (for example downloads) is transmitted. This is significantly lower than the gross transmission rate since a large part of it is required to establish and control the connection.

3 Eliminating sources of interference

The following steps are only necessary if the result of the test was at least 250 Mbit/s, but is still significantly lower when the powerline adapters are used in different electrical outlets, in different rooms or on different floors.

Note:Note that due to the FRITZ!Powerline adapter's Fast Ethernet LAN port (gross data rate of max 100 Mbit/s), the maximum speed on the entire network path cannot exceed its net data rate!

Since the throughput of powerline connections is affected by high-frequency interference signals or electrical systems with a damping effect, you can optimize the throughput by eliminating possible sources of interference:

  • Plug the FRITZ!Powerline adapters directly into a wall outlet instead of using extension cords or power strips.
  • Plug the FRITZ!Powerline adapters into different wall outlets for testing purposes.
  • 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.

    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 throughput in your powerline network is still low despite this, we cannot offer any further suggestions on how to optimize the powerline connection.
