USB 3.0 to Gigabit Ethernet Adapter - Reliable Wired LAN

Our review of this USB 3.0 to Gigabit Ethernet adapter finds it best for users who need a simple, portable way to add a true Gigabit RJ45 port to a laptop or desktop. The single biggest reason to buy is straightforward: when paired with a USB 3.0 host it delivers full 10/100/1000 Mbps throughput and supports features like Jumbo Frames and Wake on LAN, making it a useful tool for anyone who needs dependable wired network performance as an alternative to WiFi.

Key Features

• Gigabit speed: Supports full 10/100/1000 Mbps connections over USB 3.0 so large file transfers and backups run at near-native Ethernet speeds.
• Broad OS compatibility: Works natively with modern Windows, macOS, Linux kernels and ChromeOS for plug-and-play convenience on many systems.
• ASIX chipset: Uses the ASIX AX88179A chipset for reliable compatibility with laptops, desktops and 2-in-1 computers.
• Advanced network features: Supports Jumbo Frames, VLAN tagging and Wake on LAN to fit into more advanced home or small office network setups.
• Portable design: USB bus powered and compact, it is a practical travel accessory for docking stations and devices without an RJ45 port.

Who It's For

This adapter is aimed at users who need a dependable wired connection from a USB port: remote workers connecting to corporate VPNs, content creators moving large files over a LAN, and travelers using docking stations that lack a native Ethernet port. It is also handy as a backup network interface when a built-in Ethernet port fails.

Users who rely on older Intel-based Mac hardware that requires vendor drivers may want to verify compatibility first, since some customers reported mixed results on certain Mac models. If you need multiple Ethernet ports or integrated USB-C native support, consider a different multiport dock instead.
