Most routers include a USB port that goes largely unused, but manufacturers like TP-Link and Asus support turning it into a shared file server, printer connection, or even a backup internet source via cellular dongle or phone tethering. Enabling these features requires digging into router settings for options like USB storage, media sharing, or printer sharing, with setup steps varying by brand and model.
