FRITZ!Powerline 530E Service

Powerline connection is slow

The throughput of the powerline connection between two or more FRITZ!Powerline adapters is low. As a result, web pages load slowly, files take a long time to download, and video streams are either not played correctly or stop playing, for example.

Low throughput in a powerline network is usually caused by interference in the home's power supply. In the following we show how to rule out that your FRITZ!Powerline adapter is defective and how to optimize your powerline network.

1 Checking whether the FRITZ!Powerline adapters are working properly

Check whether your FRITZ!Powerline adapters function correctly in a test environment:

Downloading and installing the FRITZ!Powerline software

  1. Call up our download area in a web browser.
  2. Select the product group "FRITZ!Powerline" and then your product.
  3. Download the FRITZ!Powerline software for the operating system of your computer.
  4. Install FRITZ!Powerline on a computer with a LAN port.

Setting up FRITZ!Powerline adapters for testing

  1. Take two FRITZ!Powerline adapters between which the powerline connection is slow and plug them in next to each other on a power strip.
  2. Remove all other devices from the power strip.
  3. Use a network cable to connect one of the FRITZ!Powerline adapters to your router (for example a FRITZ!Box).
  4. Use a network cable to connect the other FRITZ!Powerline adapter to the computer on which the FRITZ!Powerline software is installed.

Determining the throughput

  1. Start the FRITZ!Powerline software.
  2. Download a file from the internet or copy a file from a different network device to the computer with FRITZ!Powerline via the adapters in the power strip.
  3. FRITZ!Powerline shows the speed between both FRITZ!Powerline adapters by the adapter that is not connected to the computer. Check the throughput given for "Send" and "Receive".
  4. Repeat steps 1 - 3 for other FRITZ!Powerline adapters if the powerline connection between them is also slow.

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

2 Reducing interference in the home's power supply

Interference in the home's power supply can severely impair communication between powerline adapters. Try to minimize the interference or eliminate it completely:

  1. Plug the FRITZ!Powerline adapter directly into a wall outlet; do not use it with a power strip or an extension cord.
  2. Avoid powerline connections on different phases, fuse boxes, and ground fault circuit interrupters (GFCI).
  3. Do not use the FRITZ!Powerline adapter behind a surge protector.
  4. For testing purposes, switch off other devices or briefly unplug them in order to identify possible sources of interference and then minimize them.

    Examples of possible sources of interference are switch mode power supplies, dimmers, halogen systems and energy-saving lamps, as well as electric motors when they are running (for example in refrigerators, food processors, dryers, washing machines, vacuum cleaners, or drills).

  5. Make sure that cables carrying a VDSL signal are laid at least 10 cm away from electrical wiring and outlets.
  6. Test different wall outlets and reduce the distance between the FRITZ!Powerline adapters.

If these measures do not sufficiently increase the speed of the powerline connection, the home's power supply is causing the issue and it cannot be further influenced by the FRITZ!Powerline adapters.
