5 Removing USB 3.0 devices from the FRITZ!Box

If you are using a FRITZ!Box with USB 3.0 support and a USB 3.0 device is connected, the USB device may interfere with the DECT connection:

  1. For testing purposes, remove all USB 3.0 devices from the FRITZ!Box's USB ports.
  2. If the problem no longer occurs, a USB device was affecting the Wi-Fi connection. Eliminate the interference caused by the USB device.
