If necessary, enable AP mode in the driver or utility to share a connection as a hotspot.

Usage recommendations

For best wireless performance place the adapter in an unobstructed USB port and avoid metal obstructions. Use the 5 GHz band for high-speed activities such as streaming and large file transfers and the 2.4 GHz band for broader range. Ensure you install the correct drivers for your OS version; Bluetooth functionality is not supported on Windows XP/Vista and may be limited on older macOS releases.
