If you are on Windows 10, 8.x, or 7—and you have an active network connection other than the Wi-Fi adapter—the driver should install automatically from Windows Update.

Once the drivers are installed, a restart is recommended. You may use the included Realtek utility and/or your operating system’s standard built-in support for making a new wireless connection to an access point.

macOS 10.15 and above are not supported as Realtek has not updated drivers and software for new requirements from Apple for DriverKit and 64-bit operation in a non-beta driver. We do not have an estimate for updated drivers from Realtek and do not expect them at this time.

There are no official drivers for the RTL8188EUS chipset, used in the adapter, for Linux. There are some community-created drivers that can be found on GitHub, but we have not found one that is reliable, and we do not support this adapter on Linux.
