USB 3.0 Gigabit Ethernet Adapter

This USB 3.0 to Gigabit Ethernet adapter adds a wired RJ45 network port to laptops, desktops, and consoles that lack one. It targets users who need a more reliable connection than Wi-Fi for gaming, streaming, or large file transfers. Driver-free operation on Windows 11, 10, 8.1, 8, macOS, and Chrome OS makes it a simple plug-and-play upgrade.

1000 Mbps speed with USB 3.0 headroom

The adapter supports up to 1000 Mbps data transfer when connected to a USB 3.0 port, delivering full gigabit throughput for online gaming and HD video streaming. It remains backward compatible with USB 2.0 ports, though speeds will be limited to the slower bus bandwidth. Performance tops out at the rated gigabit ceiling, so multi-gigabit networks cannot be saturated.

Driver-free compatibility for Switch and PC

The single deciding specification is native driver-less support for Windows 11, 10, 8.1, 8, macOS, Chrome OS, Nintendo Switch, and Switch OLED. Buyers needing kernel-level drivers for Linux distributions or legacy Windows 7 machines should verify support separately. No software installation is required for the listed platforms, enabling immediate wired connectivity.

Questions about this item

Will the adapter run at full speed on my older laptop that only has USB 2.0 ports?

It is backward compatible with USB 2.0, so it will work, but the 1000Mbps maximum throughput requires a USB 3.0 port.

How can I confirm the link is actually running at gigabit speed after I plug it in?

Check the network status on your OS; a 1Gbps link speed indicates the adapter has negotiated its full 1000Mbps capability.

Does the package include any cables or do I need to buy a separate Ethernet patch lead?

Only the adapter itself is supplied; you must provide your own RJ45 Ethernet cable to connect to the router or switch.
