Stop wasting your Wi-Fi router's USB port — try this instead

Most routers’ USB ports enable attached hard drives, SSDs, or flash drives to be shared over SMB, Samba, or FTP, and many support printer sharing via utilities like Asus’ EZ printer app. Compatible routers can also host cellular dongles or tether Android phones for primary or fail-over internet, though older models are limited to USB 2.0 speeds and power, making dedicated NAS devices more reliable for high-performance storage and redundancy.
