FRITZ!Box does not detect a mobile network dongle

The FRITZ!Box does not detect a mobile network dongle. The dongle is not displayed in the user interface under "Home Network > USB / Storage" when you connect it to the FRITZ!Box.

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

1 Installing the latest FRITZ!OS

  1. Install the latest FRITZ!OS on the FRITZ!Box.

2 Samsung GT-B3740 is not supported

Samsung's mobile network dongle GT-B3740 cannot be used with the FRITZ!Box's USB port because Samsung designed this LTE dongle for use with manufacturer-specific interfaces. This is not an error on the part of the FRITZ!Box, this is due to technical reasons on the part of the Samsung dongle.

Note:Some mobile network providers (for example Vodafone) offer the LTE dongle GT-B3740 under their own name. The FRITZ!Box recognizes the LTE dongle GT-B3740 as a USB storage device.

3 Checking whether the mobile network dongle is working properly

  1. For testing purposes, connect the mobile network dongle directly to a USB port on your computer.
  2. If the computer does not detect the mobile network dongle, then the mobile network dongle is defective. In this case, contact the manufacturer.

4 Connecting a mobile network dongle directly to the FRITZ!Box

The following step is only necessary if the mobile network dongle is connected to the FRITZ!Box via a USB hub:

  1. For testing purposes, connect the mobile network dongle directly to the FRITZ!Box (i.e. without a USB hub).
  2. If the mobile network dongle is now detected, then the USB hub is either defective or it does not support the mobile network dongle you connected.
