How to Determine Your WiFi Encryption Type: A Complete Guide

In the age of ubiquitous digital connectivity, wireless network security has ceased to be an option and has become a basic necessity. Every time you or your neighbors connect a smartphone to a router, data is exchanged that must be securely protected from prying eyes. WiFi encryption type — is a fundamental protocol that determines how difficult it is for an attacker to intercept your traffic or gain access to your local network. Understanding the current security algorithm allows you to prevent the leakage of passwords, banking data, and personal correspondence.

Many users don't even realize that their router might be running on outdated security standards like WEP, which can be cracked in minutes with modern tools. WPA2 and newer WPA3 have become the industry gold standard, but not all devices automatically switch to them when updating their firmware. In this article, we'll take a detailed look at how to audit your network's security, identify vulnerabilities, and configure the most reliable protection using built-in operating system tools and router web interfaces.

Why is it important to know your current network security protocol?

Ignoring the encryption method is like leaving the front door open, even if there's a "Beware of Dog" sign. Security protocols evolve, and old encryption methods become insecure due to the advent of new computing power and hacking algorithms. WEP (Wired Equivalent Privacy), which appeared back in 1999, is now considered completely insecure. If your router uses it, anyone with minimal IT knowledge can access your network using publicly available software.

Moreover, choosing the right protocol affects not only security but also device compatibility. Modern devices may refuse to connect to networks with outdated encryption, considering them vulnerable. WPA3, introduced in 2018, offers improved protection against brute-force attacks and encrypts data even on open networks. However, if you have older IoT devices, such as smart light bulbs or 10-year-old cameras, they may not support the new standards.

⚠️ Warning: Using WEP makes your network vulnerable to real-time traffic interception. An attacker can see which websites you visit and intercept your input unless it's protected by additional HTTPS encryption.

Understanding your current security status allows you to make an informed decision: whether to update your router firmware, replace the hardware, or simply change the settings in the admin panel. This is a basic digital hygienist skill that helps maintain your privacy online.

Checking the encryption type on Windows 10 and 11

The Windows operating system provides built-in and fairly simple tools for viewing the parameters of an active connection. You don't need to install third-party software to find out how secure your connection is. The fastest way is to use the network connections graphical interface. Click the WiFi icon in the system tray (usually on your screen), then select Properties under your network name. In the window that opens, find the line "Security type."

Here you will see an abbreviation such as, WPA2-Personal or WPA3-SAEThis is the answer to the question of how to determine the Wi-Fi encryption type without any fuss. If you see WEP or WPA, it's a signal for immediate action. You can also get more detailed information via the command line, which is especially useful if the graphical interface isn't working correctly or you want to get technical details.

Open Command Prompt (CMD) or PowerShell as administrator and enter the command:

netsh wlan show interfaces

In the command output, look for the "Authentication" field. This will indicate the protocol being used. This method is useful for diagnosing connection issues when the system reports a security error but doesn't provide any details.

It is worth noting that Windows can show mixed modes, for example WPA2-Personal AESAES (Advanced Encryption Standard) is a data encryption algorithm that works in conjunction with the WPA2 authentication protocol. The WPA2 + AES combination is considered the most compatible and secure for most home networks at this time.

How to find out the security type on macOS and mobile devices

Apple users can also easily check their security settings, although the macOS interface obscures some technical details more deeply than Windows. To find out the encryption type on a Mac, hold down the Option (Alt) on your keyboard and click the WiFi icon in the top menu bar. Find your network in the drop-down list and look at the "Security" field.

On iOS mobile devices, the situation is a bit more complicated due to Apple's privacy policy. The system doesn't display the encryption type for the current network in the standard settings menu, to reduce user anxiety. However, if the network uses an outdated security standard, iOS may display a "Weak Security" warning under the network name in the WiFi menu. This is a clear indication that the router is configured for WPA/WPA2 (TKIP) or WEP.

On Android devices, the situation varies depending on the OS version and the manufacturer's shell (Samsung One UI, Xiaomi MIUI, etc.). In stock Android 10 and above, when connecting to a network or in the properties of a saved network, a lock icon and security type are often displayed. Go to Settings → Wi-Fi → (gear next to the network name)Scroll down to the "Security" or "Advanced" section.

It may be indicated here WPA2/WPA3-PersonalThis means the router operates in mixed mode, supporting both new and old devices. It's a compromise that balances compatibility and security. If your phone displays "No encryption," it means no password is required, and data is transmitted in cleartext.

Detailed diagnostics via the router's web interface

The most reliable and complete way to find out what type of encryption is used is to look "under the hood" of the router itself. The device's web interface contains the entire wireless module configuration. To log in, you'll need the gateway IP address (usually 192.168.0.1, 192.168.1.1, or 192.168.31.1) and the administrator login and password. This information is often found on a sticker on the bottom of the device.

After authorization, you need to find the section responsible for the wireless network. It may be called Wireless, Wi-Fi Settings, Wireless mode or WLAN. Within this section, look for the subsection Wireless Security (Wireless Security) or Wi-Fi PasswordThis is where you'll find the drop-down list or radio buttons for selecting the security version.

In the interfaces of modern routers (Keenetic, TP-Link, Asus, MikroTik) you will see the following options:

• 🔒 WPA3-Personal — the most modern and safe standard.
• 🔐 WPA2-PSK (AES) — the current de facto standard, reliable and compatible.
• ⚠️ WPA/WPA2 Mixed - mixed mode to support older gadgets.
• ❌ WEP — an outdated, extremely vulnerable protocol.

You can also change the encryption type here. After changing the settings, the router will prompt you to reboot or simply disconnect from clients. You'll need to reconnect all devices using the new password or confirming the connection.

⚠️ Note: Router interfaces are constantly being updated. The menu layout may differ from what's described. If you can't find the settings, consult the official manual for your model or look for the "Wireless Security" section in the English interface.

It's also important to check your guest network settings. Users often secure their main network but leave their guest network open or weakly encrypted, which gives hackers an entry point into the local network if client isolation isn't enabled.

Comparison table of encryption protocols

To systematize your knowledge and understand the differences between abbreviations, let's review the main protocol characteristics in a table. This will help you quickly assess the risks associated with your current connection type.

As you can see from the table, the security gap between WEP and WPA3 is enormous. Upgrading from WEP to WPA2 increases the time it takes to crack a password from minutes to years, even with powerful hardware. The TKIP protocol used in early WPA is now considered obsolete and is often blocked by modern WiFi drivers due to vulnerabilities.

WPA3 introduces Simultaneous Authentication of Equals (SAE), which replaces the Pre-Shared Key (PSK) exchange. This makes offline dictionary attacks significantly harder. Even if a hacker captures the handshake, they cannot easily brute-force the password. This is a crucial upgrade for public Wi-Fi hotspots and dense residential areas.

Advanced Analysis Methods: Command Line and Utilities

For those who like to dig deeper or need to analyze not only their own but also their neighbors' networks (to select a free channel), there are advanced tools. In Windows, the command line can display a list of all saved networks and their security types. netsh wlan show profiles will list the names, and to get the details of a specific network use:

netsh wlan show profile name="Network_Name" key=clear

In the "Security settings" section, you'll see "Authentication" and "Cipher." This allows auditing of all networks the computer has ever connected to. On Linux and macOS, the equivalent utility is iwlist or airportFor example, the team sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -s On Mac, the network scanner will show you the security type (RSSI, CH, SEC).

There are also graphical utilities for Windows such as WiFi Analyzer (available in Microsoft Store) or Acrylic Wi-Fi HomeThey visualize the broadcast, showing not only channels and signal strength but also a security bar for each network. This is a convenient way to quickly assess the situation in an apartment building.

When using such utilities, pay attention to the "Security" column. If you see a network listed as "None" or "Open," be aware that traffic there is not encrypted. Connecting to such networks without a VPN is strictly not recommended for banking transactions.

Optimizing Security Settings: A Step-by-Step Checklist

Once you've determined your current encryption type, you need to update your settings to comply with modern standards. Simply knowing about the problem isn't enough—you need to fix it. Below is a step-by-step guide to maximizing your WiFi security.

The first step should always be to update your router firmware (firmware). Manufacturers regularly patch security holes that could allow encryption to be bypassed. Visit the manufacturer's website, find your model, and download the latest file, or use the automatic update feature on the web interface.

The second critical point is disabling the function WPS (Wi-Fi Protected Setup). Despite the convenience of connecting via a push-button or PIN code, this feature has fundamental vulnerabilities that allow the PIN code to be recovered within a few hours. In your router settings, find the WPS section and select "Disable" or "Off."

⚠️ Important: When you change the encryption type or password, all your devices (TVs, phones, smart plugs) will be disabled. You will need to re-enter the password on each one. Please prepare a list of devices in advance.

Use complex passwords. WPA3 encryption is useless if your password is "12345678." The combination must contain mixed-case letters, numbers, and special characters. Password length directly impacts the time required to crack it.
