How to use

Power off the desktop PC, open the case and insert the adapter into an available PCIe slot on the motherboard. Secure the card with the case bracket screw and close the housing. Boot the system, install the appropriate drivers supplied by the manufacturer or obtained from the official website, then configure wireless network settings through the operating system network manager. Use the Bluetooth settings panel to pair mice, keyboards, headsets or mobile devices. For best results, select the 5 GHz band when available for high-throughput tasks and 2.4 GHz for longer range or legacy device compatibility.

Recommendations

Place the desktop in a location with minimal physical obstructions and avoid placing large metal objects between the antenna area and the wireless router. Keep drivers up to date and use the 5 GHz band for low-latency activities such as gaming and streaming; switch to 2.4 GHz for broader coverage when needed. Verify operating system compatibility and install manufacturer drivers to enable full functionality including Bluetooth features.
