Upgrade your laptop to 2.5 Gbps Ethernet.
Instantly add multi-Gigabit connectivity to your laptop computer or desktop. Just plug the adapter into an available USB-C port and you’re ready to connect to your router or switch at 2.5x the speed of a standard Gigabit connection.

More than twice as fast as Gigabit Ethernet.
Simply plug into your computer and enjoy fast 2.5 Gigabit Ethernet that allows you to transfer large files in no time, or make light work of backups to a server or network storage device. This reliable adaptor allows you to connect to multi-gigabit speeds instantly, perfect for network intensive workloads.

Easy to install and use.
Simply plug the adapter into an available USB-C port. The installation software is already preloaded on the adapter, so there’s no need for CDs or downloads1. The portable compact design lets you easily slip the adapter into your pocket or laptop bag and take it with you anywhere.

Green technology that saves energy.
Power to the adapter is provided directly from the USB Type-C port and not only supports the USB 3.0 standard’s power-saving features, but also includes an energy-saving suspend and resume function to minimise power consumption when network traffic is light, the device is idle, or when the Ethernet cable is unplugged. Good for the environment, and ever better for your device’s battery life.

Works with existing networks.
The DUB-E250 is fully backwards compatible with existing Fast Ethernet or Gigabit networks, allowing you to connect to a wired network wherever you are.
