Wi-Fi connection problems are among the most common issues Mac users face. When your MacBook won't connect to Wi-Fi but other devices work fine, it's usually a software or settings issue rather than a hardware problem. Try these troubleshooting steps in order to resolve the connection problem.
Start with the Basics
Restart Your Mac
A simple restart often resolves temporary software glitches that can interfere with Wi-Fi connectivity. When restarting, uncheck the "Reopen windows when logging back in" option to ensure a clean startup.
Check Your Wi-Fi Connection
Make sure you're trying to connect to the correct Wi-Fi network and that the network is actually available. Verify that other devices can connect to the same network to rule out router issues.
Update macOS
Bugs in older macOS versions can cause Wi-Fi connectivity problems. Keeping your system updated ensures you have the latest fixes and improvements. Always back up your data before updating.

Hardware Considerations
If none of the software solutions work and your Mac shows "Wi-Fi: No hardware installed" or similar messages, the issue may be hardware-related. In this case, contact Apple Support or visit an Apple Authorized Service Provider for professional assistance.
Remember to work through these solutions in order, starting with the simplest fixes before moving to more advanced troubleshooting. Most Wi-Fi connection issues can be resolved without professional help using these methods.
