USB 3.0 Gigabit Ethernet Adapter

The TP-Link UE306 adds a wired RJ45 port to laptops, tablets or Ultrabooks through a USB 3.0 Type-A connection. It supports 10/100/1000 Mbps speeds for file transfers, HD streaming and online gaming. The adapter draws power from the USB port so no external supply is needed. It is also compatible with Nintendo Switch for more stable play.

Check Your Port and System

Verify the host device has a USB Type-A socket that supports USB 3.0, 2.0 or 1.1. No driver is required for Windows 10, 11, 8.1, 8, Linux or Nintendo Switch. The adapter measures 2.8 x 1.0 x 0.6 inches and weighs 0.07 pounds. A Quick Installation Guide is included in the package.

Suits Portable Wired Needs

Ideal for users who want a compact, foldable Gigabit link on ultrabooks, tablets or Nintendo Switch without installing software. Not suited for devices that only offer USB-C unless a separate hub or adapter is used. Buyers needing multi-port expansion or Power over Ethernet should look at other solutions.

Questions about this item

What comes in the package and do I need to buy a cable separately?

The box contains the UE306 adapter and a Quick Installation Guide. You will need to supply your own RJ45 Ethernet cable to connect to a router or switch.

There is only one model listed — how do I know this is the right version for my device?

The UE306 is a single USB 3.0 Type-A to Gigabit RJ45 adapter. It works with Windows 10/11, Linux and Nintendo Switch without drivers, and falls back to USB 2.0 if a 3.0 port is not available.

The spec says 1000 megabits per second — what speed will I actually see on my laptop?

The adapter negotiates 10/100/1000 Mbps with the network. Real-world throughput depends on your USB port, cable quality and network equipment, but the hardware is designed for full Gigabit Ethernet rates.
