Product information

Description

The D-Link DUB-E250 USB-C to 2.5G Ethernet adapter upgrades laptops and desktops with a USB Type-C port to multi-gigabit wired connectivity. Compact and USB-powered, it delivers up to 2500 Mbit/s in a white, pocketable design and is compatible with existing Fast Ethernet and Gigabit networks.

Advantages

The adapter provides 2.5 Gbps Ethernet speeds over a single USB-C connection, more than twice the throughput of standard Gigabit Ethernet. It includes a preloaded driver for instant plug-and-play installation, a compact portable form factor, and dynamic power management that reduces power draw when traffic is light, idle, or the cable is unplugged.

Suitable for

  • Ultra-thin laptops and notebooks with USB-C / Thunderbolt 3 ports and no built-in Ethernet
  • Desktops needing a quick multi-gigabit upgrade without opening the case
  • Transferring large files, backups to NAS or servers, and other network-intensive tasks

Key specifications

  • Model: D-Link DUB-E250
  • Interface: USB Type-C host; Ethernet network interface
  • Maximum data transfer rate: 2500 Mbit/s (2.5 Gbps)
  • Power: USB powered (draws power from USB-C port)
  • Networking standards: IEEE 802.3, 802.3u, 802.3ab, 802.3bz, 802.3x, 802.3az, 802.1Q, 802.1p
  • Colour: White
  • Weight: 0.0285 kg

How to use

Plug the DUB-E250 into an available USB-C port on your laptop or desktop. The adapter contains a built-in driver that installs automatically, enabling immediate connection to your router, switch, or network at up to 2.5 Gbps. Connect an Ethernet cable from the adapter to your network device and verify link/activity via your operating system’s network settings.

Usage recommendations

For best performance use with multi-gigabit-capable switches, routers, and cabling (CAT5e or higher recommended). The adapter is backward compatible with Gigabit and Fast Ethernet networks. To conserve battery on portable devices, rely on the adapter’s dynamic power management when traffic is light or when idle.
