Slow LAN connection to the FRITZ!Repeater

The speed of the LAN connection to the FRITZ!Repeater is considerably slower than the maximum throughput supported by the FRITZ!Repeater and the device. For example, the speed of a device's LAN connection

  • is only 100 Mbit/s although the device supports gigabit LAN connections.
  • is only 1 Gbit/s although the device is connected to a 2.5-gigabit LAN socket on the FRITZ!Repeater and it supports LAN connections of 2.5 Gbit/s or more.

Simply proceed as described below. After each measure, check whether the problem is solved.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Repeater.

1 Adjusting the LAN settings of the FRITZ!Repeater

  1. Click on 'Network' in the user interface of the FRITZ!Repeater.
  2. Click on 'Network Settings' in the 'Network' menu.
  3. Enable 'Power Mode' for all of the LAN sockets used.
  4. Click on 'Apply' to save the settings.

2 Connecting a device directly with the FRITZ!Repeater

This step is only necessary if the device is connected to the FRITZ!Repeater by means of a hub/switch, powerline device, LAN/Wi-Fi converter, or other device instead of being connected directly to the FRITZ!Repeater:

  1. Connect the device directly to a LAN socket on the FRITZ!Repeater. If possible, use the network cable included with the FRITZ!Repeater.
  2. If you can establish a gigabit LAN connection to the FRITZ!Repeater now, then the intermediary device or its cabling does not support gigabit LAN:
      1. Make sure that the devices support gigabit LAN.
      2. Update the software / firmware of the devices.
      3. Use different network cables to connect the devices to the FRITZ!Repeater. Use the shortest possible high-quality network cables (CAT 5e or higher).

3 Testing a different cable

The network cable used to connect the device to the FRITZ!Repeater may be too long, incorrectly wired, or defective:

  1. Use the shortest possible high-quality network cable to connect the device to the FRITZ!Repeater, for example use the network cable included with the FRITZ!Repeater.

    Note:Any standard network cable CAT 5e or higher (STP, 1:1) with a maximum length of 100 m can be used to connect network devices to the FRITZ!Repeater.

4 Installing the latest software for the device

  1. Install the latest software version for the device or the latest driver for the computer's LAN network adapter.

    Note:Since Windows Update often does not offer the latest drivers, install the drivers from the manufacturer's website, for example from the Intel Download Center.

5 Disabling energy-saving functions for the network adapter

  1. If any energy-saving functions are enabled for the computer's LAN network adapter or the device, disable them for testing purposes.

    Note:In Windows, different power saving functions can be set for many network adapters under 'Properties > Power Management' in the Device Manager.
