USB-C and USB-A to Gigabit Ethernet Adapter

This adapter connects a computer with either a USB-C or USB-A port to a wired 10/100/1000 Mbps network. It supports USB 1.1, 2.0 and 3.0 specifications and requires no driver installation for plug-and-play operation. An included USB-A to USB-C adapter ensures compatibility with both port types. LEDs indicate link and activity status.

Replaces Missing or Faulty Onboard Ethernet

Use this adapter when a laptop lacks a built-in RJ45 port or when the existing port has failed. It also upgrades older USB 2.0 connections to gigabit speeds where the host controller allows. The jump is worth it whenever Wi-Fi is unreliable, insecure or simply unavailable and a wired link is preferred.

Suits Mobile Workers and IT Technicians

Ideal for users who move between docking stations, hotel desks or test benches and need instant wired connectivity without opening a chassis. Not for builders who need multi-gigabit throughput beyond 1 Gbps or teams that require managed switch features such as VLAN tagging unsupported by this device.

Questions about this item

Will the 1.97" x 0.85" x 0.57" adapter block the port next to it on a slim ultrabook?

The compact housing measures 1.97" x 0.85" x 0.57" and weighs 0.09 lb, so it fits beside most adjacent ports without overhang.

Does the included USB-A to USB-C adapter (F/M) need a specific orientation when plugging into the USB 3.0 male connector?

Insert the USB-A end of the supplied adapter into the adapter's USB 3.0 male plug first, then connect the USB-C side to the host; reversing the order can prevent detection.

Should I use Cat6 or Cat6a patch cables to maintain the 1 Gbps link over longer runs?

The manufacturer recommends Cat6 or Cat6a category cable for the RJ45 female port to ensure reliable 10/100/1000 Mbps performance.
