Compact Gigabit Ethernet Adapter for USB 3.0

This USB 3.0 to Gigabit Ethernet Adapter adds a single RJ45 port to laptops and desktops through a Type-A connection. It supports 10/100/1000 Mbps networks and is backward compatible with USB 2.0 systems. The ASIX AX88179A chipset provides native driver support across Windows 7 and up, macOS 10.14 and up, Linux kernel 4.11 LTS and ChromeOS. It suits users needing a reliable wired link where WiFi is unstable or unavailable.

Bus-Powered Operation with Low Heat

The adapter draws power directly from the USB bus, eliminating the need for an external supply. Its lightweight 0.028 kilogramme chassis runs cool during typical data transfers. Status and activity LEDs give immediate visual confirmation of link speed and traffic without audible fan noise. Energy Efficient Ethernet helps reduce power draw during idle periods on supported networks.

Bundled Connectivity Tools Enhance Management

Included software adds a MAC Address Changer and Wi-Fi Auto Switch utility for Windows. These tools let administrators spoof MAC addresses for network access control and automatically disable Wi-Fi when a wired link is active. The adapter also supports 4K Jumbo Frames, VLAN tagging, Wake on LAN and Auto-MDIX crossover detection for flexible deployment.

Questions about this item

How do I install the USB31000S and which step do people often miss?

Plug the USB 3.0 Type-A connector into the host port, connect an RJ45 cable, then install the driver for the ASIX AX88179A chipset on Windows 7+, macOS 10.14+, or Linux kernel 4.11+; the step most people miss is the driver installation.

What maintenance or replacement will the USB31000S need later?

The adapter has no moving parts or user-serviceable components; keep the RJ45 port free of dust and replace the unit only if the link LEDs stop showing activity on a known-good cable.

What limit appears first under sustained use?

The USB 3.2 Gen 1 bus caps throughput at 5 Gbps, so sustained Gigabit traffic will hit the host controller bandwidth ceiling before the RJ45 1000 Mbps link saturates.
