Many routers, such as the TP-Link Archer C5400 and Linksys RT6600ax, come with built-in media server functionality. This feature allows you to stream media files directly from the connected USB storage to compatible devices like smart TVs, gaming consoles, and media players that support DLNA (Digital Living Network Alliance) standards.

Printer Sharing

Another useful feature of wireless router USB ports is the ability to share a printer with multiple devices on your network. By connecting a USB printer to your router, you can enable wireless printing for all your connected devices without the need for a separate print server or the expense of purchasing a Wi-Fi-enabled printer.

To set up USB printer sharing, simply connect your printer to the router’s USB port and install the necessary drivers on your devices. Most modern routers, like the D-Link DIR-882, offer easy-to-use interfaces for managing and configuring the connected printer.

Cellular Modem Connectivity

Some routers, often referred to as 3G/4G routers with USB or cellular modem routers, allow you to connect a USB cellular modem for failover internet access. This feature is particularly useful if your primary internet connection experiences an outage or if you need internet access in areas without traditional broadband services.

To use this feature, you’ll need a compatible 3G or 4G USB modem from your cellular provider. Once connected to the router’s USB port, you can configure the router to automatically switch to the cellular connection when the primary internet connection fails, ensuring uninterrupted internet access.

Charging Devices

While not a primary function, many routers with USB ports can also be used to charge smartphones, tablets, and other USB-powered devices. This can be a convenient feature, especially if your router is located in a central area of your home or office where you often need to charge your devices.
