Is Your Phone Saying You have “Weak Security?" Here’s What it Means...

Written by CoreTech Staff | Jun 15, 2021, 6:18:00 PM

Has your mobile device alerted you to “weak security” recently? 

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update patches from Apple and Android will now show an alert for weak security if your router or modem is using an outdated network security key. 

What are network security keys?  

Network security settings help keep your Wi-Fi network safe from unwanted users. You may see terms like WPA2, WPA3, AES, and TKIP in your router or network settings. They can sound technical, but they simply describe how your Wi-Fi network verifies devices and protects information sent over the connection.

Your Wi-Fi password is also part of your network security, but it is different from the security setting itself. The password lets approved users join the network, while the security setting helps protect the connection.

Here are the most common security settings:

  • WEP: An outdated security option that is no longer recommended. It is easier to compromise and should be avoided.
  • WPA: An older option that is also no longer recommended for modern networks.
  • WPA2: A widely used option. When configured with AES encryption, WPA2 remains a secure choice for many networks.
  • WPA3: The newest commonly available option, offering stronger protections when supported by your router and devices.

 

Which Network Security Key is Best: WPA2-AES or WP3?

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.

Why am I receiving this “weak security” alert on my mobile device? 

If your device displays a “Weak Security” alert, it usually means your Wi-Fi router is using an older security setting. It does not necessarily mean your Wi-Fi password has been exposed or that someone has accessed your network.

The warning may appear if your router is using WEP, WPA, TKIP encryption, or another outdated mixed security setting. These options can make it easier for someone to access or interfere with your Wi-Fi network.

For better protection, update your router to WPA3 when possible. If WPA3 is not available, WPA2 with AES encryption is still a secure option for many home and business networks. 

Do I need to take action? If so, how do I resolve this error message? 

If you see this message while connected to your home or office Wi-Fi, it is a good idea to update your router settings. Using an older security setting can make your network less secure and may create connection issues with newer devices.

To resolve the warning, you may need to:

  • Reconfigure your wireless router security settings to WPA3.

     

  • Use WPA2 with AES encryption if WPA3 is not available.

     

  • Use a WPA2/WPA3 transitional setting if older devices need to stay connected.

     

  • Update your router’s firmware and your devices’ software.

     

  • Replace an older router if it cannot support WPA3 or WPA2 with AES encryption.

After changing your router settings, you may need to “forget” the Wi-Fi network on your phone, tablet, or computer and then reconnect. CISA also recommends keeping router software current and avoiding older protocols such as WEP, WPA, and TKIP.

Not sure which setting to choose? Check your router manufacturer’s support instructions or contact your IT provider. The right setting depends on your router, software version, and the devices connected to your network.
