Dual-Port USB 3.0 Gigabit Adapter

This USB 3.0 network adapter adds two Gigabit Ethernet ports and a USB 3.0 pass-through port through a single USB Type-A connection. It uses the ASIX AX88179A chipset for native compatibility with laptops, desktops and 2-in-1 devices. The adapter supports 10/100/1000Mbps speeds with Auto MDIX crossover detection. It is designed for users who need wired network redundancy or separate VLAN connections on the go.

Verify USB Port and OS Version

Ensure your system has an available USB Type-A port running USB 3.0 for full bandwidth, though it will fall back to USB 2.0 at reduced throughput. Supported operating systems include Windows 7 and later, Windows Server, macOS 10.14 and later, Linux Kernel 2.6.25 LTS and Chrome OS. Driver installation is not required for plug-and-play operation on these platforms. Buyers who need driver support for older kernels or unsupported operating systems should look elsewhere.

Bus-Powered Portable Network Expansion

The compact adapter draws power directly from the USB bus, requiring no external power supply for operation. It frees up your laptop's single Ethernet port by providing two independent Gigabit links for teaming, failover or segmented traffic. The integrated USB 3.0 pass-through port preserves your USB connectivity for peripherals or storage. Builders who need Power over Ethernet input or SFP module slots will not find those features here.

Questions about this item

What comes in the box and is anything else needed to use the adapter?

The box contains the USB 3.0 dual Gigabit Ethernet adapter with a USB 3.0 pass-through port, a driver CD and an instruction manual. No extra items are required because the device is USB bus-powered and works plug-and-play on supported operating systems.

How do I choose between the available versions or capacities of this model?

This model is offered as a single configuration with two Gigabit Ethernet ports and one USB 3.0 Type-A pass-through port. There are no alternate port counts or speed tiers to select.

What does the 1000Mbps rating mean when the adapter is connected to a laptop?

Each of the two Ethernet ports supports up to 1000Mbps full-duplex throughput. Actual transfer rates depend on the host USB 3.0 link, cable quality, network switch capability and system load.
