Optimizing Wi-Fi Performance on Your PC: Practical Solutions and Troubleshooting Tips

Experiencing sluggish Wi-Fi speeds on your PC can be incredibly frustrating, especially when standard troubleshooting steps don’t yield improvements. If you’re facing persistent connectivity issues and subpar speeds despite being close to your router, you’re not alone. This comprehensive guide aims to help you diagnose and resolve common Wi-Fi performance problems, ensuring you get the most out of your internet connection.

Understanding Your Hardware and Setup

1. Hardware Specifications:

2. Wireless Adapter: Intel(R) Wireless-AC 9560 160MHz

3. Motherboard: ROG STRIX Z390-I GAMING
4. Internet Service: Fiber optic connection capable of up to 800 Mbps

5. Household Devices: Similar devices achieving 300-400 Mbps on Wi-Fi

6. Observation Summary:

7. Your PC consistently receives only one bar of Wi-Fi signal, even when placed directly next to the router.

8. Ethernet connection speeds previously reached 75 Mbps without fiber, but now are limited to approximately 1.5 Mbps.
9. The same Wi-Fi card in an upstairs PC achieves 200–300 Mbps, indicating a potential hardware or configuration issue.

Troubleshooting Steps

1. Confirm Basic Connectivity:

2. Restart your router and PC to refresh network settings.

3. Check if other devices experience similar slowdowns, suggesting an issue with the network rather than your PC.

4. Assess Wi-Fi Signal Quality:

5. Use network diagnostic tools or Wi-Fi analyzer apps to measure signal strength and interference.

6. Confirm that your PC is connected to the appropriate frequency band (2.4 GHz vs. 5 GHz) and that it matches your router settings.

7. Review Network Adapter Settings:

8. Access Device Manager > Network Adapters > Intel(R) Wireless-AC 9560.

9. Under Properties > Advanced, experiment with settings like Bandwidth, Roaming Aggressiveness, and Preferred Band.

10. Disable Power Saving Mode under Power Management to prevent the adapter from reducing performance.

11. Update Drivers and Firmware:

12. Download the latest drivers for your Wi-Fi card from Intel’s official website.

13. Ensure your motherboard BIOS and router firmware are up to date.

14. Check for Interference and Obstacles:

15. Although your router is close, consider potential interference from other electronic devices.

16. Switch the Wi-Fi channel on your router to reduce congestion.

17. Evaluate Hardware Integrity:

18. Given the disparity between your PC’s speed and that of similar devices, hardware issues could be
