Transfer rate of LAN connections to the FRITZ!Repeater is only 100 Mbit/s

The maximum transfer rate of the LAN connection between the FRITZ!Repeater and a computer, NAS system, or other devices is 100 Mbit/s, although the device supports LAN connections of one gigabit 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 repeater

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

2 Connecting a device directly with the repeater

This step is only necessary if the device is not directly connected to the FRITZ!Repeater, but through a hub/switch, powerline device, LAN/Wi-Fi converter, or other devices instead:

  1. Connect the device directly to a LAN port 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 better).

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:

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.

6 Disabling EEE (Energy Efficient Ethernet) in the repeater

With EEE, network adapters can be put into an energy-saving standby mode, thus also significantly reducing their average power consumption. Since there may be compatibility issues with individual network adapters when EEE is enabled, disable EEE for testing purposes:

Links "Help and Info" and then "FRITZ!Repeater Support"
  1. In the user interface of the FRITZ!Repeater, click "Help and Info" on the bottom left of the page and then on "FRITZ!Repeater Support" at the bottom.
  2. Enable the option "Disable EEE (Energy Efficient Ethernet)" in the "Ethernet Compatibility" section.
  3. Click "Apply setting" to save the settings.
