The latest update patches from Apple and Android will now show an alert for weak security if your router or modem is using an outdated network security key.
Network security keys are more commonly known as WiFi passwords. They help keep your network safe from unwelcome users.
They provide authorization for wireless access, and there are a few common types.
You’ve likely seen these key types in your network settings, but may not have known what they’re for or what they mean.
Within WPA2, there are different encryption algorithms that can be used, including AES (Advanced Encryption Standard) and TKIP (Temporal Key Integrity Protocol). WPA2-AES offers strong, efficient encryption, while WPA2-TKIP, intended for backward compatibility, is less secure due to known vulnerabilities. AES is recommended for maximum security, while TKIP should be used sparingly and only when backward compatibility is essential.
Between WPA2-AES and WPA3, WPA3 is generally considered the more secure option. WPA3 offers enhanced security features over WPA2, including stronger encryption protocols and protection against offline dictionary attacks. However, the choice between WPA2-AES and WPA3 depends on factors such as device compatibility and support within your network infrastructure. If possible, opting for WPA3 is recommended for better security.
If your device is giving you a weak security warning, it’s because you’re connected to a Wi-Fi network using a network security key that’s no longer considered secure. The “weak security” alert is prompting you to reconfigure your Wi-Fi router to a key with better encryption technology and security protocols.
Specifically, if you’re using a router configured to WPA-PSK security key, you’ll receive this alert. Why? A pre-shared key (PSK) only involves remembering one password, and it is more easily compromised than next-generation encryption.
If you’re using your mobile device and see this message when connected to your home network, you do need to take action for two reasons.
To resolve this error message, you need to either:
Before reconfiguring your router, you also must update your devices with the latest patches for software and firmware. You can check for these in your device’s settings.
After changing the settings on your Wi-Fi router, you might need to “forget” your network and then rejoin to be sure the device applies those new settings.
