Overview
Add powerful connectivity to your USB-C enabled laptop, tablet or desktop computer. Ideal for mobile use, this USB-C to Ethernet adapter plugs into your USB-C or Thunderbolt™ 3 port to provide wired network access, and gives you three USB 3.0 Type-A ports to connect your peripheral devices. Plus you can charge your laptop as you work. It makes a great companion for your MacBook, Chromebook Pixel™, Dell™ XPS 12, or other device.
Access reliable Gigabit network connections
Gain a wired internet connection virtually anywhere you go. The USB-C network adapter provides an Ethernet port that supports full Gigabit bandwidth by harnessing the performance of USB 3.0 (5 Gbps), also known as USB 3.1 Gen 1. You can connect to a network in locations where Wi-Fi® is unavailable or unreliable, and quickly access large files over the network at Gigabit speed.
Enhance productivity with a 3-port USB hub
Some USB Type-C laptops, tablets and computers have only one port for external connectivity, which limits the number of peripheral devices you can use. This USB-C Ethernet adapter features a built-in hub with three USB Type-A ports, giving you the freedom to attach additional devices, such as a USB mouse or flash drive. You can expand the number of USB ports you have to enhance your productivity.
Gain easy portability
Travel-sized and self-powered, this USB-C network adapter and hub provides easy portability, tucking easily into your laptop bag and eliminating the need to carry a separate Gigabit Ethernet adapter and USB-C to USB-A hub. It’s ideal for mobile use, providing you with wired network connectivity wherever you go, and letting you plug in extra USB peripheral devices. It also has a built-in USB-Type-C cable so it’s always there when you need it.
Power and charge as you work
The USB-C network adapter lets you power and charge your laptop as you work, while powering the hub at the same time. The adapter supports Power Delivery 2.0, so instead of carrying multiple power adapters, you can use your laptop’s USB-C power adapter to power both your laptop and network adapter. Note: just make sure your laptop’s USB-C based power adapter supports USB Power Delivery 2.0.
Install it with ease
Get up and running quickly. Simply plug the adapter into the USB Type-C™ port on your laptop and connect to your network. It automatically installs once you connect it, and works with a wide range of operating systems such as Windows®, macOS, Linux® and Chrome OS™.

Frequently Asked Questions
Before You Buy
USB-C is a type of USB connector that is capable of supporting the following:
- Data transfer speeds up to 10Gbps, if you use USB 3.1.
- Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
- Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).
If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-port-capabilities.
Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers.

Troubleshooting
When you troubleshoot issues with a network adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
- Ethernet cables
- Network devices
- Computer system
To test your setup components, try the following:
- Use the Ethernet cables, network devices, and computer system in another setup to see if the problem is with the components or the setup.
- Use different Ethernet cables, network devices, and a different computer system in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
- Test each cable individually.
- Use short cables when you are testing.
When you test the Ethernet cables, network devices, and computer system, it is recommended that you do the following:
- In Device Manager, check under Network Adapters. To open Device Manager, press the Windows key + R, type devmgmt.msc, and press Enter.
- If you are using a USB network adapter and you do not see the network adapter listed in Device Manager, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows.
- If you are using a PCI/PCIe network adapter and you do not see the network adapter listed in Device Manager, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows.
- If you are using a CardBus/ExpressCard adapter and you do not see the network adapter listed in Device Manager, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#cb-ec-cannot-detect-windows.
- If the device is listed with an error, follow the instructions on the product page to reinstall the drivers.
- Check to see if your network devices (for example, a network switch, router, and so on) use compatible protocols (for example, 10/100, Gigabit, and so on).
- Make sure that the link LEDs on the adapter are illuminated when it is plugged into a network device. If the link LEDs are illuminated, it means that a good electrical connection exists between the devices.
- If you use a wall jack with an Ethernet cable, make sure that the jack is patched in properly.
