Why wont my Macbook connect to Wifi?

Experiencing issues with your MacBook not connecting to WiFi is fairly common, and most people are likely to run into this issue at some point.

There are some common reasons why this occurs. This includes;

  • Hardware Issues
  • Incorrect Network Settings
  • Outdated software
  • Interference
  • System Setup Conflicts

Though there’s various different reasons why this may happen, you can usually resolve it by running through the following troubleshooting steps.

Check Your WiFi Settings

The first step in troubleshooting is to ensure that your WiFi is enabled on your MacBook, and that you’ve got an established connection.

Though it may seem simple enough, often the reason why you can’t access the internet is explained by your device. You may see a message like “No Internet Access, which can indicate an interference issue.


You can check this by clicking on the WiFi icon in the menu bar. Also, verify that you are trying to connect to the correct network.

Forget and Reconnect to the Network

Sometimes, removing the WiFi network from your list of known networks and reconnecting can solve the issue.

To do this, the first thing we need to do is click intoSystem Settings.


Next, select WiFi, and click on the menu button next to the network you’re connected to (the three dots).


You’ll then be presented with the option to forget the network. Try doing this and reconnecting to see if there was just an error with your setup.

Use Network Diagnostics

What many people aren’t aware of is that their MacBook actually has a built-in WiFi diagnostics tool. To use it, hold the Option key and click on the WiFi icon in the menu bar, then select ‘Open Wireless Diagnostics.’


You can then follow the on-screen instructions to identify and resolve WiFi issues.

Check for Signal Interference

Signal interference is still surprisingly common in a world where it seems like WiFi is everywhere. From the devices we use in our home (like microwaves & Bluetooth speakers) to the distance between you and your router, there are various things that can create signal interference.

So whilst you’re trying to resolve the issue, make sure you’re within a reasonable distance of your router.

Restart Your MacBook and WiFi Router

Restarting your Macbook is another common way to resolve connectivity issues. Not only should you restart your MacBook, but it’s also a good idea to reboot your WiFi router too.

Restarting your device is the best way to ensure what you’re experiencing isn’t a temporary glitch or error.

Update Your macOS

Running an outdated operating system could be the reason you’re having WiFi connectivity problems. You can check for any available macOS updates by going to the Apple Menu and selecting About This Mac.


Here, you’ll see a button with a prompt to update to the latest version of macOS if it’s available.

By following these steps, you should be able to resolve most WiFi connectivity issues on your MacBook.
