You can connect various USB devices such as printers or storage devices to both of the USB 3.0 ports on the FRITZ!Box. The devices are then available in the FRITZ!Box home network.

1 Supported USB device classes

The FRITZ!Box supports USB devices from the following device classes:

  • USB storage device

    Note:The FRITZ!Box supports USB storage devices with a maximum of four partitions formatted with the file system NTFS, FAT/FAT32 or ext2/ext3/ext4. Each partition may be up to 4 terabytes in size.

  • Mobile network dongle (LTE/UMTS/HSPA)

    Note:Instead of a mobile network dongle, you can also use the mobile internet connection of an Android smartphone (USB tethering).

2 Total number of USB devices

If you use a USB hub, you can connect up to four USB devices (not including the USB hub) to the FRITZ! Box at the same time, including a maximum of one USB printer and a mobile network dongle. If you use the FRITZ!Box remote connection software, you can connect up to three USB devices (not including the USB hub) to the FRITZ!Box at the same time.
