The D-Link DUB-1312 is a Hi-Speed USB 3.0 to 10/100/1000 Mbps Gigabit Ethernet Adapter specifically designed to plug into an available Universal Serial Bus (USB) port on a desktop or Windows laptop PC or Apple MacBook. Based on USB 3.0, the DUB-1312 extends the transfer speed of earlier USB Fast Ethernet adapters to true 10/100/100 Mbps connectivity.

As a USB device, installation and use are further simplified by living up to USB's out-of-the-box installation approach to connecting computer peripherals. The D-Link DUB-1312 represents the simplest way to connect your computer to an Ethernet based network.

The D-Link DUB-1312 provides a standard RJ-45 connector for a quick and simple method of connecting to an Ethernet 10 Mbps, Fast Ethernet 100 Mbps or Gigabit Ethernet 10/100/1000 Mbps based LAN via a network hub or switch. The built-in USB 3.0 cable connects directly to your computer or laptop.

Power for the DUB-1312 is provided directly by the USB bus, eliminating the need for an external power adapter. It also supports USB's energy saving suspend and resume functions to minimize power consumption, which is especially useful for laptop/notebook users.
