What "Weak security" warning on Wi-Fi means

The weak security warning you’ve received on your Mac is an alert from Apple, indicating that your Wi-Fi network's security settings are outdated and may expose your information to hackers. It happens when your Wi-Fi network isn’t using the latest security standards. The situation is more concerning than issues like a MacBook connected to Wi-Fi but no internet. As the Wi-Fi network administrator, you can update your Wi-Fi router settings to improve your Wi-Fi’s security and potentially block hackers from accessing your network.

Ways to fix weak Wi-Fi security warning on Mac

To address the Wi-Fi security warning on your Mac, update your Wi-Fi network's password and your router’s firmware. If you're unsure how to proceed, consult your network administrator or check your router’s manual for guidance. It's also essential to update your Mac to the latest macOS version to ensure its software is up-to-date.

Furthermore, you may need to forget the Wi-Fi network on all previously connected devices. This ensures they adopt the router’s updated settings upon reconnection. If you're unfamiliar with this process, follow our guide on how to forget Wi-Fi on Mac. Thereafter, you can fix the weak security WPA MacBook warning.

Encountering a Wi-Fi no hardware installed notification when attempting to reconnect to your Wi-Fi network on a Mac can also be resolved by updating your router's firmware.

To mitigate a weak Wi-Fi security warning on your MacBook, consider the following actions:

1. Update your Mac if it doesn’t have the latest software updates
2. Type your router’s IP address into your browser’s URL/search bar
3. Update your router firmware to the latest version
4. Change the security/encryption settings on your router to WPA3
5. Create a strong password for your network

1. Update your Mac if it doesn't have the latest software updates

Whenever you encounter issues or errors on your Mac, one of your first fixes should be to check for the latest software updates and implement them as needed. Regular software updates from Apple provide critical security enhancements to protect against hacking and data theft.

By taking advantage of Apple’s free software updates, you help your Mac keep its defenses up.

Follow these steps to update your MacBook Pro or Air:

1. Click on the Apple menu in the top menu bar and select About This Mac.
2. Hit the Software Update button, check the listed results, and select Restart Now. If your Mac has found updates, you can implement them.

2. Type your router’s IP address into your browser’s URL/search bar

Now that your Mac’s software is updated, your next task is to update your router’s firmware. To do this, copy and paste your router’s IP address into your browser’s search bar and enter your login credentials.

Here’s how to find your router’s IP address on a Mac:

1. Click on the Apple menu and select System Preferences > Network > Wi-Fi.
2. Head to the Status section and find the sequence of numbers—this is your router’s IP address.

3. Update your router firmware to the latest version

If you’re the Wi-Fi network administrator, consider installing the latest version of your router’s firmware. After opening your router’s interface, find the firmware or update section and follow the instructions. Additionally, you might want to use Apple's recommended settings for Wi-Fi routers and access points.

4. Change the security/encryption settings on your router to WPA3

Apple recommends using WPA3 Personal for improved security. WPA3 Personal is the latest, most secure protocol available for Wi-Fi devices. It works on some older devices, too. If you own an older device that doesn’t support WPA3 Personal, set your security to WPA2/WPA3 Transitional instead.

To change your Wi-Fi network configuration, sign in to your Wi-Fi router’s interface or website, look for firmware updates, and reconfigure the Wi-Fi router for WPA3 Personal.

5. Create a strong password for your network

Last but not least, secure your Wi-Fi network by using a strong password.
