WiFi security protocols like WEP, WPA, WPA2, and WPA3 determine how well your wireless network protects your data from unauthorized access. Using a modern protocol such as WPA2 or WPA3 significantly reduces the risk of hacking, while outdated options like WEP leave your information vulnerable. Confirming which security type your Windows 11 PC uses is a crucial first step toward securing your network and personal information.

Check WiFi Security Type Using Windows 11 Settings

Step 1: Click the network icon in the lower-right corner of your taskbar to open the quick settings panel. This icon typically looks like a WiFi signal or a globe.

Step 2: Select the WiFi network you are currently connected to. If you’re not connected, join your preferred wireless network first.

Step 3: Click on Properties under your current WiFi connection. This opens a page with detailed information about your network.

Step 4: Scroll down to the Properties section. Here, look for the entry labeled Security type. The value displayed (such as WPA3-Personal, WPA2-Personal, WPA, or WEP) shows which security protocol your network is using.

Using this method provides a quick overview of your network’s protection level. If you see WPA3 or WPA2, your network uses strong encryption. If the security type is WPA or WEP, your network is at greater risk of unauthorized access, and you should consider upgrading your router’s settings.

Check WiFi Security Type via Control Panel

Step 1: Press Win + R to open the Run dialog box. Type control and press Enter to launch the Control Panel.

Step 2: In the Control Panel, navigate to Network and Internet > Network and Sharing Center.

Step 3: Click on Change adapter settings in the left sidebar. Find your active WiFi adapter, then double-click it to open the WiFi Status window.

Step 4: In the WiFi Status window, select Wireless Properties.

Step 5: Switch to the Security tab. Here, you’ll see both the Security type and Encryption type used by your current connection.

This approach not only reveals the security protocol but also the encryption method, giving you a more detailed understanding of your network’s defense. For example, WPA2 with AES encryption is considered highly secure.

Check WiFi Security Type Using Command Prompt

Step 1: Open the Start menu, type cmd, then right-click Command Prompt and choose Run as administrator.

Step 2: Enter the following command and press Enter:

netsh wlan show interfaces

Step 3: Review the displayed information. Look for the line labeled Authentication. This line indicates your WiFi security type, such as WPA3-Personal, WPA2-Personal, WPA, or WEP.

This method is especially useful for users who prefer command-line tools or need to script checks across multiple devices. It also displays other details about your wireless connection, such as signal strength and radio type.

Understanding WiFi Security Types and Next Steps

WiFi security protocols have evolved to address vulnerabilities and improve data protection. Here’s a quick summary:

  • WEP: The oldest and weakest protocol, easily compromised by attackers.
  • WPA: An improvement over WEP, but still susceptible to certain attacks.
  • WPA2: Uses AES encryption, offering strong protection for most users.
  • WPA3: The latest standard, introducing stronger encryption and better resistance to brute-force attacks.

If you discover your network uses WEP or WPA, update your router settings to WPA2 or WPA3 for better security. Access your router’s admin interface—usually by entering its IP address into a web browser—and look for wireless security settings. Choose the highest protocol your devices support, set a strong password, and apply the changes. If your router doesn’t support WPA2 or WPA3, consider replacing it with a newer model to keep your data safe.

Regularly updating your router’s firmware, using unique passwords, and enabling available security features will further reduce your exposure to network threats.

Checking your WiFi security type in Windows 11 takes just a few minutes and can make a big difference in protecting your data. Upgrading to a stronger protocol and keeping your router updated will help keep your network safe from intruders.
