How to Fix MacBook Not Connecting to Wi-Fi

Whether you want to book a flight, send an important email or watch the latest season of The Big Bang Theory, you can't live without the Internet. If your MacBook won't connect, it's going to cause problems for you. So it is very important to make sure your internet connection is working properly.

Confirm your Wi-Fi is on

Please check to make sure you didn't accidentally turn off Wi-Fi. You can do this by following these steps: Go to the Apple menu in the upper left corner and click System Settings (or System Preferences) > Network. If you find the "Turn on Wi-Fi" button in the interface, click it and connect to your network. Make sure the Wi-Fi connection is working properly.

Confirm your Wi-Fi password

Please ensure that the Wi-Fi password you enter is accurate, and pay attention to the password length, complexity, and case distinction .

Check for System Updates

If your laptop is not running the latest version of macOS, it may slow down your Mac and affect your Wi-Fi connection. To check for software updates:

Make sure your computer is connected to power. Depending on your device, follow one of the following paths to turn on Software Update: On a Mac, go to Apple Menu > System Settings. Then click General on the left and Software Update on the right. Alternatively, go to Apple Menu > System Preferences and click Software Update. If an update is available, click Upgrade now. Don't close the lid or put your Mac to sleep while it's installing new software. If your laptop is up to date, you won't see a prompt to install new software.

It's always a good idea to back up your computer before updating your operating system.

Restart your Mac

If you've tried the previous tips and your Mac still can't connect to Wi-Fi, just restart to get your wireless internet back Resume and run again.

Generally speaking, it's a good idea to restart your laptop once a week. You'll clear temporary files and close programs, which can prevent problems from occurring.

Please follow these steps to restart your laptop:

Click the Apple menu in the upper left corner of the screen. Select Restart. After restarting your computer, you will have the option to automatically reopen your current browser tabs and applications. In this case, don't select it. Just make sure you save everything first.

Automatically set date and time on Mac

Making sure the date and time are set correctly ensures your messages, emails, and files have accurate timestamps. It can also help fix Wi-Fi glitches.

On macOS Ventura 13

On your Mac, choose Apple Menu >System Settings. Click "General" in the sidebar, then click "Date and Time" on the right (you may need to scroll down). Turn on Automatically set time and date, click Settings, and enter the network time server for your region. Turn on Automatically set time zone using your current location.

On macOS Monterey 12 and Big Sur 11

On Mac, go to Apple Menu > System Preferences, then click Date & Time. Look at the lower left corner – if the lock icon is locked, click it to unlock the preference pane. Click on the date and time. To set the date and time automatically, select Set date and time automatically, and then select a network time server appropriate for your region. Click on the time zone. To set the time zone automatically, select Set time zone automatically using current location.

Check your V or security software

A Virtual Private Network (V) is a great way to keep your personal and professional information safe and anonymous, but it could be why your Wi-Fi isn't working .

To check if your V (or security software) is the culprit, turn it off and see if your Wi-Fi problem persists. For more information, read our guide on what a V is and whether you really need one.

Try the built-in diagnostic tools

If Wi-Fi on your MacBook still isn't working, one of the built-in diagnostic tools on your computer may help.

Wi-Fi Recommendation

Go to Apple Menu > System Settings > Control Center. Click Wi-Fi and look for a menu item called Wi-Fi Suggestions. If you see it, your computer has discovered the problem and provided suggestions for fixing it. To learn more, select Wi-Fi Recommended.

Wireless Diagnostics

Hold down the Option key and click the wireless icon (Wi-Fi symbol) in the status menu in the upper right corner of the screen. In the menu, click Open Wireless Diagnostics. Click Continue to let your Mac run diagnostics on your network connection. After the analysis is complete, click the Info button in the Summary pane to learn more about each item in the list.

Update Your Wi-Fi Router

Most routers automatically update when connected to the Internet. To find out if your router supports it, head to your router's administrative settings page, where you can check for any software updates.

You can also try restarting the router. For more tips, check out our guide to choosing the best Wi-Fi router for your home.

Try a different network

Still can’t connect your Mac to Wi-Fi? Try a different network. Depending on where you are in your home, it might make more sense to try a long-range 2.4 GHz network instead of a 5 GHz network, which is faster but has a shorter range.

Switching networks should be as simple as clicking the Wi-Fi symbol in the upper right corner, clicking the opposite network name (it usually has a 2.4 or 5 in the name), and entering your password if you haven't done so already ).
