USB 3.0 Gigabit Ethernet Adapter

The LUOM SLMU101 adds a wired Gigabit Ethernet port to a laptop or desktop through a USB 3.0 Type-A connection. It suits users replacing a faulty internal network card, adding a second routed interface, or moving large files over a stable cable link. The compact dongle measures five inches end to end and requires no external power. It is backward compatible with USB 2.0 and 1.1 hosts.

Practical limits of USB 3.0 and Gigabit Ethernet

The upstream USB 3.0 link caps at 5 Gbps, so the 1000 BASE-T Ethernet port cannot exceed that throughput. Real-world speed also depends on the host controller, cable quality, and network congestion. The adapter negotiates down to 10 or 100 Mbps on older switches and supports Energy Efficient Ethernet to reduce idle power draw. Wake-on-LAN and auto MDIX are supported where the OS and switch allow them.

Check your setup before ordering

Verify the host has a free USB Type-A port and runs Windows 2000, XP, Vista, 7, 8, 8.1, 10 (32 or 64-bit), macOS 10.6 or later, Chrome OS, or Linux with native driver support. The device does not work with Windows RT, Android, Wii, Wii U, or Nintendo Switch. A Cat 6 Ethernet cable is required for best performance and is not included. Ensure your router or switch provides a compatible RJ45 port.

Questions about this item

Which LUOM SLMU101 version should I pick for Gigabit Ethernet?

The SLMU101 is a single model that adds a 10/100/1000 Gigabit RJ45 port via USB 3.0 type A; no capacity or version options are offered.

What does the 5 Gbps USB 3.0 rate mean for real network speed?

The USB 3.0 upstream link runs at up to 5 Gbps, letting the adapter deliver full 1000 BASE-T Gigabit Ethernet throughput when paired with a Cat 6 cable.

How does the USB 3.0 interface cap performance in practice?

The USB 3.0 type A connection supports 5 Gbps, well above the 1 Gbps Ethernet line rate, so the wired link — not the USB bus — sets the practical ceiling.
