Every device connects to the wifi except for my Mac Mini

Troubleshooting Wi-Fi Connectivity Issues on Mac Mini

Encountering connectivity problems with a Mac Mini can be frustrating, especially when other devices such as smartphones and laptops connect without issue. If your Mac Mini is unable to connect to your Wi-Fi network despite entering the correct password, and the network is functioning properly for other devices, there are several troubleshooting steps you can take to identify and resolve the issue.

Understanding the Problem

In this scenario, your Mac Mini previously connected to your Wi-Fi network seamlessly. Now, it refuses to establish a connection, despite the password being verified as correct. Notably, the Mac Mini can connect to your phone’s hotspot, indicating that the hardware is capable of connecting to wireless networks. The router, located in the same room, appears to be functional.

Step-by-Step Troubleshooting Guide

1. Verify Basic Connectivity

2. Restart Your Devices: Begin by restarting your Mac Mini and your Wi-Fi router. Power cycle both devices to refresh network settings.

3. Confirm Signal Strength: Ensure your Mac Mini is within a good range of the router and that there are no physical obstructions or interference sources.

4. Check Network Settings on Your Mac Mini

5. Forget and Reconnect to the Network: Go to System Preferences > Network > Wi-Fi > Advanced. Select your network and click ‘Remove’ or ‘-‘ to forget it. Then, reconnect by selecting the network and entering the password again.

6. Verify Network Settings: Ensure your Mac Mini is set to obtain IP addresses automatically via DHCP. You can verify this in System Preferences > Network > Wi-Fi > Advanced > TCP/IP.

7. Investigate Security and Compatibility

8. Confirm Password Accuracy: Double-check that the Wi-Fi password is correct, paying attention to case sensitivity and special characters.

9. Check for Network Compatibility: Ensure your router’s security settings are compatible with your Mac Mini’s capabilities. For example, if the router uses a very new or uncommon security protocol, your Mac might have trouble connecting.

10. Update Software and Firmware

11. Update macOS: Make sure your Mac Mini is running the latest version of macOS, which can resolve known compatibility issues.

12. Update Router Firmware: Check the router manufacturer’s website for firmware updates that can improve stability and compatibility.

13. Reset Network Settings and PRAM/NVRAM

14. Reset Network Preferences: Removing network interfaces and restoring defaults can resolve corrupt settings.

15. Reset PRAM/NVRAM: Restart your Mac and hold down Option + Command + P + R during startup
