## Summary description

TRENDNET TU3-ETG is a compact interface adapter delivering up to 2 Gbit/s data transfer rate.

## Long description

TRENDNET TU3-ETG is a compact external interface adapter that adds a Gigabit Ethernet port to a computer via a SuperSpeed USB 3.0 connection. The white module measures 72 × 25 × 15 mm and supports Full Duplex data transfer up to 2 Gbit/s when connected to a compatible USB 3.0 host. Designed for simple expansion or upgrading of network connectivity, this adapter is suitable for desktop network devices, small office setups and home networking tasks. The device is compatible with Windows and Mac systems and can operate with older USB 2.0 and 1.1 ports at reduced speeds.
Advantages
The TRENDNET TU3-ETG provides reliable wired network access without opening a computer chassis or installing internal hardware. Its SuperSpeed USB 3.0 interface enables up to 2 Gbit/s full duplex throughput on supported hosts, and backward compatibility with USB 2.0 and 1.1 ensures connectivity to a wide range of systems. The compact, energy-efficient design incorporates GREENnet technology to reduce power consumption by up to 70% during idle or low-activity conditions, and the small white enclosure is unobtrusive on desks or in portable setups.
Suitable for
Adding a Gigabit Ethernet port to laptops or desktops without an available LAN jack
Small office and home office environments that require stable wired connections
Home networking tasks such as streaming, file transfers and online gaming when Wi‑Fi is insufficient
Temporary network setups or travel where a compact external adapter is preferred
Key specifications
Maximum data transfer rate: up to 2 Gbit/s full duplex (with USB 3.0 host)
Host interface: SuperSpeed USB 3.0; backward compatible with USB 2.0 and 1.1
Network port: Gigabit Ethernet (10/100/1000 Mbps)
Physical dimensions: 72 × 25 × 15 mm
Color and enclosure: white compact external module
Power: bus-powered via USB connection; energy-saving GREENnet technology
Operating systems: compatible with Windows and Mac platforms
How to use
Connect the TRENDNET TU3-ETG to an available USB 3.0 port on the computer; the adapter will negotiate the highest supported speed depending on the host and USB version. Attach a standard Ethernet cable from the adapter's Gigabit port to a router, switch or modem to establish a wired network connection. On first use, install any required drivers provided by the operating system or TRENDNET if prompted; subsequent connections should be recognized automatically on supported Windows and Mac systems. If connected to a USB 2.0 or 1.1 port, expect lower transfer speeds consistent with those standards.
Usage recommendations
For optimal performance, use a USB 3.0 host port and a quality Cat5e or Cat6 Ethernet cable. Place the adapter where the cable is not under strain and avoid exposing it to moisture or extreme temperatures. When using battery-powered laptops, note that bus-powered operation draws power from the host; GREENnet technology reduces idle consumption but active transfers will use more power.
