Two-Pack Wired Connectivity

This two-pack supplies a pair of USB 3.0 to Gigabit Ethernet adapters for adding wired network ports to laptops, ultrabooks or desktops that lack an onboard RJ45 jack. Each adapter weighs only 0.032 kilograms and draws power directly from the host USB port, so no external supply is required. Driver-free operation is supported on Windows, macOS and Chrome OS, enabling instant plug-and-play deployment in offices, hotels or home networks.

Best For Single-Port Expansion

The adapters suit users who need a reliable wired link for large file transfers, video streaming or secure connections where Wi-Fi is congested or unavailable. They also provide PXE boot and MAC address clone support via the Windows utility for managed deployments. Buyers who require multi-gigabit throughput, additional USB ports or a dock with video outputs should consider a full docking station instead.

USB 3.0 Interface Defines Speed

The USB 3.0 host connection limits sustained throughput to the SuperSpeed 5 Gbps signalling rate, which in practice caps real-world traffic at the 1000 Mbps Ethernet ceiling. Systems equipped only with USB 2.0 ports will fall back to 10/100 Mbps operation. Verify that the host device offers a USB 3.0 Type-A port before purchase.

Questions about this item

Will the 1000 Mbps link work on my older laptop that only has USB 2.0 ports?

The adapter is backwards compatible with USB 2.0, but the 5 Gbps SuperSpeed rate requires USB 3.0; on USB 2.0 the connection will fall back to 10/100 Mbps network speeds.

How can I confirm the adapter is negotiating a full 1000 BASE-T connection after I plug it in?

Check the link LEDs on the RJ45 port — they indicate 10/100/1000 Mbps status — and verify the connection speed in your OS network settings.

Does the two-pack include Cat 6 cables or do I need to buy them separately?

Cat 6 Ethernet cables are sold separately; the box contains two USB 3.0 to Gigabit Ethernet adapters only.
