USB 3.0 Gigabit Ethernet Adapter

The LUOM SLMU101 adds a wired RJ45 network port to any computer with a USB 3.0 Type-A socket. It delivers 10/100/1000 Mbps Ethernet speeds and is backward compatible with USB 2.0 and 1.1. The compact 5-inch dongle requires no external power and supports Windows 2000 through Windows 10, macOS 10.6+, Chrome OS, and Linux.

Ideal for Restoring or Adding a Wired Link

This adapter suits users replacing a failed onboard LAN port or adding a second isolated network interface for file transfers or secure management traffic. It supports Wake-on-LAN and full-duplex operation for standard desktop and laptop workflows. It is not for buyers who need a connection on devices lacking a USB-A port, such as tablets, phones, or Nintendo Switch consoles. It also does not support Windows RT or Android platforms.

USB 3.0 Type-A Upstream Interface

The single specification that determines compatibility is the host port: the device must provide a USB 3.0 Type-A connector to achieve Gigabit throughput, though it will fall back to 10/100 Mbps on USB 2.0. The 5-inch cable length fixes the adapter's reach from the host port. Verify your system has the required USB-A socket before purchase.

Questions about this item

Will the USB 3.0 type A connector or the 5 in. cable need replacing first?

The USB 3.0 type A upstream port and the 5 in. cable are fixed parts of the adapter; neither is designed as a user-replaceable component.

Does the 1000 BASE-T link or the USB 3.0 5 Gbps bus saturate first during sustained transfers?

The 1000 BASE-T Ethernet link at 1000 Mbps reaches its ceiling well before the USB 3.0 bus at 5 Gbps.

How warm does the SLMU101 get when plugged into USB 3.0 all day?

The adapter supports IEEE 802.3az Energy Efficient Ethernet and draws power only from the USB port, so it runs cool during continuous operation.
