The D-Link DUB-E250 USB Type-C to 2.5G Ethernet adapter provides a wired network connection for laptops and desktops that lack a built-in Ethernet port. The adapter connects via a standard USB Type-C interface and supports data transfer rates of up to 2500 Mbit/s, providing higher bandwidth than standard Gigabit connections. It is a wired-only device without Wi-Fi functionality and features an integrated 0.16-metre cable.
The device is USB-powered and requires no external power supply. It is plug-and-play, meaning no manual driver installation is necessary. It is compatible with Windows 7 through 10, and Mac OS X versions 10.6 to 10.15. The unit is compact, weighing 28.5 grams with a 53-millimetre housing, and includes built-in LEDs to indicate network status.
Key Features:- Single RJ45 port supporting 10, 100, 1000, and 2500 Mbit/s Ethernet LAN speeds for backward compatibility.
- Full-duplex transmission.
- Auto-negotiation and auto MDI-X for automatic cable pairing and speed selection.
- Hardware support for VLAN tagging (IEEE 802.1Q) for use in enterprise network environments.
- Flow control to manage network traffic under heavy loads.
- Low power consumption of 0.25 W to reduce battery drain on connected mobile host devices.
