USB 3.0 to Gigabit Ethernet Adapter

The DBIT RU301 adds a wired RJ45 network port to any computer with a USB-A 3.0 socket. It delivers full 10/100/1000Mbps speeds for stable file transfers, video calls, gaming and HD streaming. The adapter draws power from the USB bus and works driver-free on Windows 11 down to XP, macOS, Linux and Chrome OS. A nylon-braided cable and aluminium housing provide durability in a 28 gram package.

Laptops, Ultrabooks and tablets lacking a built

Ideal for users who need a reliable wired connection on devices that only have USB-A. Not suited for hardware that provides only USB-C ports unless a separate USB-C to USB-A adapter is used. Buyers who require multi-gigabit speeds beyond 1000Mbps should look at a different class of adapter. The single-port design also limits use to one wired link at a time.

RTL8153B controller with USB 3.0 interface

The built-in RTL8153B chip enables gigabit throughput with low power draw and efficient heat dissipation. Backward compatibility with USB 2.0 and 1.1 ensures it functions on older ports at reduced speed. To achieve the full 1000Mbps rate the link requires CAT6 or better cabling. IEEE 802.3az support adds Energy Efficient Ethernet operation.
