Whoever has a free USB port on their internet router has a great treasure: why and what is it for?

Routers , as we all know, are hardware devices that serve as a connection point between a local network and the internet. That is, they guide and direct network data through packets containing various types of data, such as files, communications, and simple transmissions like web interactions .

Data packets appear to have several layers, or sections . One of them carries identifying information, such as the sender, data type, size, and, most importantly, the destination IP (Internet Protocol) address. The router reads this layer, prioritizes the data, and chooses the best route for each transmission.

In recent years, numerous models have included a USB port that often goes unnoticed. It's more than just an input: those who use it daily discover a series of functions that significantly improve overall productivity, convenience, and digital security at home .

Among the positive aspects of this technological trick for the home , the following stand out:

• Create a private cloud without paying for external services . With the close collaboration of certain advanced configurations, it can function as a personal cloud. Users save their files to a USB drive connected to the router and access them from anywhere.
• It allows you to share files just like a home server . By connecting an external hard drive or USB flash drive, the router allows any device connected to the network to access the stored files.
• Share a printer without cables or Bluetooth . People who have a printer without Wi-Fi can convert it to a wireless printer by simply connecting it to the router's USB port.
• Download files . Yes, even with your computer off. Some router models allow you to manage downloads directly from the network, using built-in managers or third-party applications.
• Easily automate backups . Many routers allow you to schedule automatic backups from your computer to a USB-connected drive.
