- Connect the Ethernet adapter to your computer
- Install driver. Follow platform specific instructions below:
Windows® 10 or 11: With existing network connection, drivers install automatically via Windows Update, it will usually be in the 'Optional Updates' section. You can also download the driver package from the drivers page.
Other Windows® Versions: Download the driver package from the drivers page.
macOS (10.13.6-10.15): Basic in-box driver support, but for full performance, visit our drivers page to download an updated driver
macOS (11.x): No driver install available, use built-in NCM driver. Note: There are known issues with incorrect link rate reporting and packet counts on macOS 11.x. With auto-negotiation, the adapter will get a 2.5Gbps connection, and the device operates normally, but it will appear in macOS that the link rate is only 1000Mbps. Jumbo frames are not currently supported on macOS 11.x. We are working with Realtek on drivers to resolve these issues
Linux (5.x Kernel+): In-box driver support, recommended to install driver on lower kernel versions
Earlier macOS and Windows Versions: for a driver download, visit our drivers page.
- Connect the adapter to your network.
