If your MacBook can’t connect to WiFi, it could be due to a range of issues, from simple settings mishaps to more complex hardware problems.
This guide will walk you through troubleshooting steps to identify and solve the problem.

Check WiFi Settings

First, ensure that your WiFi is turned on.

If the WiFi is on and you still can’t connect, try turning it off and on again.

Restart Your Router and Modem

Many connectivity problems are solved by a simple restart.

Unplug your router and modem from power, wait for about a minute, and then plug them back in.
Allow a few minutes for them to fully restart.

Restart Your MacBook

Sometimes, a fresh start can solve connectivity issues.

Go to the Apple menu and select Restart.

Allow your MacBook to fully reboot and see if it connects to WiFi.

System Logs

Checking system logs can provide insight into the problem.
