TRENDnet TU3-ETG — wired Gigabit for laptops and PCs with a USB-A port
USB 3.0 Type-A1x RJ45 GigabitBus poweredNintendo Switch
The TRENDnet TU3-ETG is a USB 3.0 to Gigabit Ethernet adapter that turns a free USB Type-A port into a 10/100/1000 Mbps RJ45 network port. It is meant for laptops without a network socket, desktops whose onboard LAN has failed, and anyone who wants a stable wired connection instead of Wi-Fi for video calls, large downloads or remote work.
The adapter has a short integrated cable (about 13 cm), takes its power from the USB port and needs no external supply. TRENDnet lists Windows 11, 10, 8.1 and 7, macOS 10.6 to 12, and Nintendo Switch in docked mode. The current hardware version is v3.0R, which TRENDnet rates at 0.95 W maximum power draw.
Before you order: Full Gigabit speed needs a USB 3.0 (blue or SS-marked) port. On a USB 2.0 port the adapter still works, but throughput is limited by USB 2.0 to well below 1 Gbps. For USB-C only laptops, choose the TUC-ETG instead.

What It Means in Practice
- Gives a thin laptop without an RJ45 socket a reliable wired connection at the office desk.
- Replaces a failed onboard network port on a desktop without opening the case.
- Wired Ethernet is usually more stable than Wi-Fi for Teams/Zoom calls, gaming and large file transfers.
- Useful for IT staff as a spare adapter for configuring switches, routers and firewalls.
- On the Nintendo Switch dock it provides wired online play instead of Wi-Fi.
- Wake-on-LAN from suspend is supported, depending on the host computer.
What Will Not Work
- USB-C only laptops (e.g. recent MacBooks) without a USB-A port or a USB-C to USB-A adapter.
- Speeds above 1 Gbps — this is not a 2.5G adapter.
- Full Gigabit speed on a USB 2.0 port.
- Charging or video output — it provides a network port only.
- Linux is not in TRENDnet's published OS list.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
The TU3-ETG is a dependable, small adapter from a networking brand, and the integrated cable is kinder to laptop ports than rigid plug-in dongles. If you also need extra USB ports, HDMI or charging on the same desk, one of our docking stations may replace several adapters at once.
✓ Buy it if your laptop or PC has a USB-A 3.0 port and you want a stable wired Gigabit connection.
✕ Skip it if your laptop has USB-C ports only, or you need 2.5G speeds.
→ Also consider TRENDnet TUC-ETG for USB-C, or i-tec U3METALGLAN for a metal-housed USB-A adapter.
