Gigabit USB 3.0 Adapter for Laptop and Switch

This USB 3.0 to RJ45 dongle adds a wired gigabit port to laptops, MacBooks and the Nintendo Switch or Switch OLED. It suits users whose built-in Ethernet is missing or faulty and who want a stable link for gaming, streaming or large transfers. The adapter works driver-free on Windows 10, 11 and macOS, while Windows 7 and Linux require a simple driver install.

Thermals Noise and Power in Daily Use

The compact black enclosure weighs just 0.04 kg and draws power directly from the USB port, so no external supply is needed. An LED indicator shows link status without adding audible noise. Backward compatibility with USB 2.0 is supported, though the connection will not reach gigabit rates on that older interface.

Upgrade From Wi-Fi or Slow Ports

The adapter replaces unreliable wireless or a 100 Mbps port with a full 1000 Mbps wired link. The jump is worthwhile when low latency and consistent throughput matter for competitive gaming or HD streaming. It is not suited for buyers who need multi-gigabit speeds beyond 1 Gbps or who require a USB-C connection instead of USB-A.

Questions about this item

How do I install the UGREEN RTL8156BG USB 3.0 Gigabit Ethernet Adapter, and what step do people often miss?

Plug the adapter into a USB 3.0 port and connect an RJ45 cable; the step often missed is rebooting the computer after installing the driver on Windows 7, XP, Vista, or Linux, as the adapter will not work until after the restart.

What maintenance or replacement will the UGREEN RTL8156BG adapter need over time?

The adapter itself has no user-serviceable parts or scheduled maintenance; replacement is only needed if the USB connector, RJ45 port, or internal RTL8156BG chip fails due to physical damage or wear.

What limit appears first when using the UGREEN RTL8156BG adapter continuously at high throughput?

The first limit is the USB 3.0 interface bandwidth and the RTL8156BG chip's 1000Mbps maximum; if plugged into a USB 2.0 port, the speed drops well below gigabit regardless of sustained load.
