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warning you’ve received on your Mac is an alert from Apple, indicating that your Wi-Fi network's security settings are outdated and may expose your information to hackers.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.

5. Create a strong password for your network

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