Gigabit USB 3.0 adapter

The UGREEN RTL8156BG adds a wired RJ45 port to any device with a USB-A 3.0 socket. It delivers up to 1000 Mbps throughput for gaming, streaming and large transfers. The dongle measures 6.2 in x 2.6 in x 1.8 in and weighs 0.04 kg.

Driver-free on modern systems.

Windows 11, 10, 8.1, 8, macOS and Chrome OS work without extra software. Windows 7, XP, Vista and Linux require the supplied driver. Nintendo Switch and Switch OLED are supported plug-and-play; Wii and Wii U are not.

USB-A 3.0 host requirement for gigabit speed

The adapter uses a USB 3.0 Type-A plug and is backward compatible with USB 2.0 ports, though gigabit rates cannot be reached on the older interface. A USB-A 3.0 port on the host is therefore the deciding factor for full performance.

Questions about this item

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

The box contains one adapter with a built-in USB-A plug. A standard Ethernet cable with RJ45 connectors is required and is not included.

The title shows 1000Mbps and USB 3.0 — which version should I pick for my laptop?

This single model supports up to 1000Mbps over USB 3.0 and works with Windows 11, 10, 8.1, 8, macOS and Chrome OS without drivers.

Will I actually see 1000Mbps throughput on my Nintendo Switch OLED?

The adapter is plug-and-play on Switch and Switch OLED and can deliver gigabit speeds when your router and cable support it; USB 2.0 ports will limit the rate.
