Gigabit Ethernet via USB 3.0

This compact adapter adds a Gigabit Ethernet port to any computer through a single USB 3.0 connection. It operates at 10, 100 or 1000 Mbps and supports full duplex communication. An integrated USB 3.0 pass-through port keeps the host port available for other peripherals. The white enclosure measures .7 by 1.4 by 3.2 inches and weighs 1.80 oz.

Mobile users needing wired networking

Suits laptop or tablet owners who require a reliable wired link without sacrificing their only USB 3.0 socket. The pass-through port allows a flash drive, mouse or charging cable to stay connected. Not intended for desktop builders who need a dedicated PCI Express network card or for users whose devices lack a USB 3.0 or 2.0 port entirely.

AX88179 and VL811 chipset combination

The ASIX AX88179 controller handles the Gigabit Ethernet function while the VIA VL811 hub manages the USB 3.0 pass-through. Together they deliver 1000 Mbps throughput with checksum offload, large send offload, 4K jumbo frames and IEEE 802.1Q VLAN tagging. Auto MDIX corrects cable polarity automatically. A driver CD and manual are included.

Questions about this item

What Ethernet speeds does the USB 3.0 interface support in practice?

The adapter negotiates 10, 100 or 1000 Mbps over the RJ45 port; the USB 3.0 link provides enough bandwidth for full gigabit throughput.

What physical space and connectors are required to fit the adapter?

It measures .7 by 1.4 by 3.2 inches and weighs 1.80 oz; you need a free USB 3.0 Type-A socket and room for the RJ45 jack and the pass-through USB 3.0 Type-A port.

How is the adapter installed and what step do users often miss?

Plug the male USB 3.0 connector into the host, connect the network cable to the RJ45 port, then run the driver installer from the included CD or download the latest driver before expecting the gigabit link to appear.
