USB 3.0 Gigabit Ethernet adapter

This USB 3.0 to Gigabit Ethernet adapter adds a wired network port to any laptop or desktop with a free USB 3.0 Type-A socket. It delivers 10/100/1000 Mbps speeds over standard twisted-pair cabling up to 100 metres. The compact dongle measures 1.00" x 0.90" x 2.70" and weighs 0.05 lb, drawing power directly from the USB bus. IEEE 802.3az support enables energy-efficient operation.

Replaces missing or failed onboard Ethernet

Use this adapter when a built-in RJ-45 port is absent, damaged or limited to slower speeds. The jump is worthwhile if you need full Gigabit throughput and have a USB 3.0 port available; USB 2.0 would bottleneck the connection. It also serves as a quick diagnostic spare for IT staff troubleshooting client, server or workstation links without opening the chassis.

Fits any USB 3.0 host with driver support

Plug the male USB Type-A connector into a USB 3.0 port and connect an RJ-45 patch cable to the female jack. The adapter operates from 0 to 50 °C (32 to 122 °F) and stores from 0 to 70 °C (32 to 158 °F) at 10–90 % RH. Auto MDIX handles crossover detection, while IEEE 802.1Q VLAN tagging supports managed networks. A driver CD and manual are included for systems without in-box drivers.

Questions about this item

What physical space does the 1.00" x 0.90" x 2.70" adapter need beside a USB 3.0 port?

The adapter measures 1.00" x 0.90" x 2.70" and plugs directly into a USB Type-A 3.0 port; allow enough clearance for the RJ-45 cable bend radius so the connector does not press against adjacent ports or the chassis.

Which driver step is most often missed when installing the USB31000NDS on Windows?

Run the setup from the included Driver CD before connecting the adapter; if the hardware is plugged in first, Windows may bind a generic driver and the adapter will not reach 1000Mbps until the correct driver is installed and the device is reconnected.

When should the USB31000NDS be replaced based on its operating temperature rating?

The adapter is rated for 0 to 50 °C operating temperature; if the enclosure regularly exceeds 50 °C or the unit becomes too hot to touch during normal use, replace it to avoid thermal degradation.
