How to use

Insert the CF-727B into an available USB 2.0 port on your computer. Install drivers from the included CD or download the latest drivers from the manufacturer’s website if required by your operating system. After driver installation the adapter will appear in the system network and Bluetooth settings; use those system utilities to connect to a Wi‑Fi network or pair Bluetooth devices. If necessary, enable AP mode in the driver or utility to share a connection as a hotspot.

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.
