UGREEN USB 3.0 to RJ45 Gigabit Ethernet Adapter Black

USB 3.0 to Gigabit Ethernet Adapter

The UGREEN USB 3.0 to RJ45 adapter adds a wired network port to devices that lack one, such as ultrabooks, tablets or the Nintendo Switch. It connects via a standard USB-A male plug and provides a female RJ45 jack for 10/100/1000 Mbps Ethernet. The adapter draws power from the USB bus and includes link and activity LEDs for quick status checks. It suits users who need a stable wired connection for file transfers, video calls or gaming.

Verify Your Device Has a USB-A Port

Before ordering, confirm that your computer, tablet or console offers a free USB-A socket; the adapter’s connector is USB-A male and will not fit USB-C, Lightning or Micro-USB ports without a separate adapter. Check that your operating system appears in the supported list: Windows 8.1, 8, 7, Vista, XP, Mac OS X 10.6 through 10.12, Linux kernel 2.6 or 3.x, or Chrome OS. Note that Windows RT and Android are explicitly not supported. The adapter is backward compatible with USB 2.0 and 1.1 hosts, though speed will be limited by the slower bus.

Replaces a Missing or Damaged RJ45 Port

This adapter replaces a broken onboard Ethernet jack or adds wired networking to hardware that never included one, such as modern ultrabooks or the Nintendo Switch. The upgrade is worth it when wireless signals are unreliable, latency matters for competitive gaming, or large file transfers saturate Wi-Fi bandwidth. It also serves as a sacrificial port, protecting the computer’s built-in RJ45 connector from wear in docking scenarios. If your device already has a working Ethernet port and strong Wi-Fi, the adapter adds no benefit.
