Understanding and fixing common Wi-Fi problems is important for getting a reliable internet connection. Here are some key things to think about:

1. Signal Strength

• Distance: Wi-Fi signals get weaker the farther away you are from the router. At about 30 feet away, you could lose half of your signal strength.
• Obstacles: Things like walls, floors, and furniture can block signals. Metal items can bounce signals around and reduce performance by about 30%.

2. Interference

• Channel Congestion: If many Wi-Fi networks are close together, it can cause interference. In the 2.4 GHz band, there are only 3 channels that don’t overlap (1, 6, and 11). Too many networks can make the connection crowded.
• Devices: Microwaves and Bluetooth devices also work on the 2.4 GHz band and can slow down Wi-Fi performance by about 20-30% when they are in use.

3. Security Protocols

• Encryption Types: Using old security settings can hurt your performance. WEP is weak and can be hacked in under 5 minutes, while WPA2 offers much better protection.
• Access Control: Filtering MAC addresses can improve security, but it might also cause some working devices to disconnect, which can reduce performance by up to 10%.

4. Firmware Updates

• Router Updates: Not updating your router’s software can create security risks and lower performance. Regular updates can boost performance by about 15-20%.

5. Tools for Diagnosis

• Utilize Apps: Use apps that analyze your network to check signal strength, find interference sources, and see if firmware updates are needed. This could improve your network's reliability by around 25%.

By focusing on these key areas, you can greatly enhance your Wi-Fi connection and keep your internet strong for both personal and work needs.
