Before we dive into the troubleshooting process, it’s essential to understand the basics of Wi-Fi connectivity. Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables. Your Mac uses a Wi-Fi adapter to detect and connect to nearby networks. The Wi-Fi adapter is usually built-in, but you can also use an external adapter if needed.

Wi-Fi Network Requirements

To connect to a Wi-Fi network, you’ll need to ensure that your Mac meets the following requirements:
Your Mac must be within range of the Wi-Fi network.
The Wi-Fi network must be broadcasting its network name (SSID).
You must have the correct network password or passphrase.
Your Mac’s Wi-Fi adapter must be enabled and configured correctly.

Checking Your Wi-Fi Adapter

To check if your Wi-Fi adapter is enabled, follow these steps:
Click the Apple menu and select System Preferences.
Click Network.
Select Wi-Fi from the list on the left.
If Wi-Fi is not enabled, click the checkbox next to Wi-Fi to enable it.
If you’re using an external Wi-Fi adapter, ensure it’s properly connected to your Mac.
