Connect your disk to the router to access stored files from anywhere on the network, including videos and music

Our modem can become a great hub for preserve all important files present between various PCs, simply using the USB port (present on many latest generation models) and connecting an external USB hard disk. This simple link will turn any USB disk into a network diskaccessible from any PC with Windows but also usable from Macs, mobile phones and Smart TVs.

In this guide we will show you how to put a hard disk on the network via the modem’s USB porttaking advantage of the network sharing features found on modems sold in recent years, including many modems provided by Internet telephony operators.

1) How to connect hard disk to a modem

USB Router Before proceeding with the rest of the guide, let’s make sure that the modem at our disposal has at least one USB port on the back (preferably USB 3.0 type, recognizable by the blue color of the contacts). The port should be enabled foraccesso al file system NTFSthe most used for very large discs.

Once this important check has been carried out, we connect any external USB disk of at least 1 TB and let’s continue with the rest of the guide to access disk space from any network device.

On some drives, make sure to use a hard drive case with a separate power supply, so you don’t have power problems when you connect the hard drive to your router. For further information we can read our guide to best portable external hard drives.

2) Enable network disk sharing

file sharing
Once we have connected the hard disk to the modem we access the configuration panel from a browser on any connected device, to see if it can be used to share files over the network. The IP addresses most used by routers are e In case of problems, it is best to refer to the router manual or check the label on the bottom or back of the device, so you can verify the access address and credentials to use.

Once inside the router we look for one of the following entries:

  • File sharing
  • Samba/SMB
  • Disk sharing
  • USB sharing
  • USB configuration
  • USB hard disk

With one of these entries we will have access to the functions reserved for sharing files on the network. The entries and screens change depending on the router model you have, but the features are pretty much the same everywhere.

For sharing we can activate various services, the most famous are:

  • DLNA: with this service the modem will check the presence of multimedia files (video, audio, images) on the connected unit, so as to make them visible to any other device on the network. If we have a Smart TV we will be able to access the disc via Wi-Fi or Ethernet and immediately see all the films saved on the disc from the DLNA app or from the video player integrated into the TV.
  • File Sharing: with this service it will make the entire connected drive visible to other devices on the network, which will be able to read, modify and create new files or folders as if it were a drive present in the system.

Some router models also have printer support (Print Server), which is very useful for making printing available to all devices on the network without using WiFi or an Ethernet cable (not all printers support these features).

3) Best routers for file sharing

If our modem does not have USB ports and/or does not support sharing services we can buy a new router to obtain these features, without necessarily having to change the old modem provided by the telephone operator, as seen in the guide above how to change fiber modem even if restricted by the operator.
