In today's digital world, wireless networks have become an integral part of our lives and businesses, providing instant access to information from anywhere. However, by leaving the network open or using weak security protocols, users effectively open the door to attackers who can intercept traffic, steal passwords, or use your internet for illegal activities. This is why the question arises: How to check Wi-Fi security type, is becoming critical for every router owner, whether it is a home device or corporate equipment.
Understanding the encryption protocol used on your network allows you to assess its vulnerability and, if necessary, take steps to strengthen security. Modern standards provide reliable data encryption, while outdated methods have long been considered insecure and are easily cracked even by novices using readily available software. In this article, we'll detail methods for checking the current security status on various operating systems, explain the differences between protocols, and help you choose the optimal configuration for your equipment.
Before diving into technical details and settings, it's important to clearly understand the difference between a network password and the security protocol itself. A password is the access key you enter when connecting, while the security protocol is the mathematical algorithm that encrypts data packets transmitted between your device and the router. WPA3, WPA2 and outdated WEP — these aren't just abbreviations in settings; they're fundamental standards that determine how difficult it is for an outsider to decipher your internet traffic.
Basic types of encryption and security protocols
To properly assess the security of your wireless network, it's essential to understand the evolution of the Wi-Fi Alliance standards that govern data encryption methods. The development of these protocols is a constant arms race between security developers and hackers seeking vulnerabilities. Today, routers and operating systems offer several main options, each with its own characteristics and security level.
The very first and most vulnerable standard is WEP (Wired Equivalent Privacy). Although it was intended to provide a level of security equivalent to a wired connection, in practice this protocol has proven extremely weak. The encryption algorithms used in WEP allow an attacker to intercept enough data packets and calculate the access key in minutes, sometimes even seconds, using publicly available tools. If your router is still operating in WEP mode, it should be reconfigured immediately, as it provides no real protection against hacking.
WEP was replaced by the protocol WPA (Wi-Fi Protected Access), which served as a stopgap solution until the full IEEE 802.11i standard was implemented. WPA used a more advanced algorithm, TKIP (Temporal Key Integrity Protocol), which dynamically changed encryption keys for each data packet. This made cracking significantly more difficult than WEP, but TKIP was eventually deprecated due to vulnerabilities discovered. Today, using pure WPA without the "2" or "3" prefix is not recommended for either home or office networks.
The gold standard for many years remains WPA2 (Wi-Fi Protected Access 2), which is based on an advanced encryption algorithm AES (Advanced Encryption Standard). AES is used by government and military agencies to protect highly classified information, demonstrating its high reliability. Unlike its predecessors, WPA2-AES provides strong encryption that is virtually impossible to crack by brute-force attacks or traffic analysis within a reasonable time, provided a complex password is used.
The latest standard is WPA3, which was introduced relatively recently to address some theoretical vulnerabilities in WPA2 and improve security on public networks. WPA3 implements brute-force protection even in offline mode and uses more complex handshake methods when connecting devices. However, it's important to note that older devices may not support this protocol, which will lead to connection issues, so upgrading to it should be done with care.
⚠️ Attention: If you see an open network without a lock icon or a network with WEP security type in the list of available networks, we strongly recommend against transmitting confidential information, such as bank card details or logins for important services, through them.
Below is a comparison table to help you quickly navigate the characteristics of the various protocols and understand which one is right for you:
| Protocol | Encryption algorithm | Security level | Recommendation |
|---|---|---|---|
| WEP | RC4 | Critically low | Do not use |
| WPA (TKIP) | TKIP | Short | Replace with WPA2 |
| WPA2 (AES) | AES | High | Recommended |
| WPA3 | AES-GCMP | Very tall | Optimal for new devices |
Choosing the right protocol is a balance between hardware compatibility and security. In most modern scenarios, using the WPA2/WPA3 Mixed is the most reasonable compromise, allowing new devices to benefit from improved security while older devices continue to operate online without loss of functionality.
Checking the security type on a Windows computer
The Windows operating system provides users with sufficient tools to diagnose their current connection without requiring third-party software. The fastest way to find out the security type of your active network is to use the standard settings interface, which is available in all versions of the system, from Windows 7 to the latest Windows 11. This method is ideal for a quick check without delving into technical details.
To begin, you need to open the Start menu and go to the Settings section by selecting the gear icon, or simply press a key combination Win + INext, select the "Network and Internet" category, which displays the current connection status. In the network status window, find the "Properties" or "Hardware Properties" link. Clicking this will take you to a detailed description of your Wi-Fi connection. In this list of parameters, find the "Security type" line, which will indicate the protocol used, for example, WPA2-Personal.
For more advanced users who prefer the command line, Windows offers a powerful tool netsh, which allows you to obtain detailed information about wireless interfaces. This method is especially useful if the graphical interface is not working correctly or if you need to copy precise technical data. Open the command prompt (cmd) as an administrator and enter the following command:
netsh wlan show interfacesIn the command output, find the line "Authentication," which will indicate the current authorization method. You can also get a detailed report on saved networks by entering the command netsh wlan show profiles, and then drill down to a specific network with the command netsh wlan show profile name="Network_Name" key=clearThe "Security settings" section will indicate the encryption type and protection method.
☑️ Wi-Fi diagnostics on Windows
It is worth noting that in corporate environments the protocol is often used 802.1x, which requires additional authorization through the server. In this case, you'll see this security type in the connection properties, which means you'll need to enter the employee's login and password, not just the network key. This is a more complex but also more secure access method that allows for flexible user rights management.
How to find out the security protocol on Android and iPhone smartphones
Mobile devices are the most common wireless network clients, and Android and iOS operating system manufacturers offer various ways to view connection details. However, unlike desktop operating systems, mobile platforms often hide technical information deep within menus to avoid cluttering the user interface.
On devices running Android The path to this information may vary depending on the system version and manufacturer's shell (Samsung One UI, Xiaomi MIUI, Stock Android). Typically, you need to go to "Settings," select "Wi-Fi" or "Connections," and tap the name of your active network or the gear icon next to it. In the menu that opens, look for "Security" or "Security Type." On some devices, this information may be hidden and only becomes visible after tapping "More" or "Advanced Settings."
To the owners iPhone And iPad iOS is less fortunate: it's impossible to view the encryption type (WPA2/WPA3) for the current network in the settings interface using standard tools. Apple hides these technical details from the user, relying on automatic selection of the best protocol upon connection. The only way to obtain this information on iOS is to use third-party Wi-Fi analyzer apps from the App Store, such as AirPort Utility (requires enabling a hidden feature in settings) or Fing, which scan the airwaves and provide a detailed report on network parameters.
Why are security settings hidden on iPhone?
Apple adheres to the principle of interface minimalism, believing that encryption type is a technical detail that requires no user intervention. The system automatically selects the most secure protocol supported by the router and device.
It's important to understand that mobile devices often support a "Randomized MAC Address" feature, which changes the device identifier each time you connect to enhance privacy. While this feature doesn't change the encryption type of the communication channel itself, it is an important addition to the overall security of your online presence.
⚠️ Attention: Mobile operating system interfaces are frequently updated. If you don't find the "Security" option in the locations described above, search for "Wi-Fi" or "Security" in your settings, or consult your specific smartphone's documentation.
Android users also have access to a hidden, yet very informative, testing method via the engineering menu or ADB (Android Debug Bridge), but this requires a computer connection and certain skills. For most cases, the standard settings menu, which displays the connection status and security type, is sufficient.
Detailed check via the router's web interface
The most reliable and complete source of information about your network's security level is the router itself. The router's web interface is the control panel where you configure all wireless network settings, including the SSID (network name), password, and, of course, the encryption protocol. Logging into the admin panel not only gives you access to view but also the ability to change settings, making this method the most effective.
To access the interface, open any browser on a device connected to the router's network and enter the gateway's IP address in the address bar. Most often, this is 192.168.0.1, 192.168.1.1 or 192.168.31.1, but the exact address can be found in the Windows command line using the command ipconfig (the "Primary Gateway" line) or on a sticker on the bottom of the device. After entering the address, the system will ask for your login and password. If you haven't changed them, they'll also be on the sticker or are the default (admin/admin).
After successful authorization, the interface will offer you a settings menu. Navigation may vary depending on the brand (TP-Link, Asus, Keenetic, MikroTik), but the logic remains the same. You need to find the section related to wireless mode. It may be called "Wireless," "Wi-Fi," "Wireless Network," or "WLAN." Within this section, look for the "Wireless Security" subsection.
Here, in the "Version" or "Security Mode" drop-down list, the currently active protocol is displayed. You'll also see the selected encryption algorithm (AES or TKIP) and whether a password is set. This location not only allows you to view the settings, but also allows you to correct the situation if you detect the use of outdated WEP or Open Mode.
Some modern routers, especially mesh systems and models with Wi-Fi 6 support, may have a simplified interface where protocol selection is automated. In these cases, the settings may include a checkbox labeled "WPA2/WPA3 Mixed" or "Recommended Settings," meaning the router dynamically selects the best option for each connecting client.
Analyzing the surrounding airwaves using third-party utilities
For information security specialists and advanced users who want the most complete picture of what's happening in the radio airwaves, specialized analyzer programs are available. These snails scan all available networks and provide detailed technical information about each one, including channel, signal strength, equipment vendor, and, of course, security type.
One of the most popular and free programs for Windows is inSSIDer (old versions are free, new ones are paid) or WiFi Analyzer (available in the Microsoft Store). These apps visualize your wireless environment, displaying channel congestion graphs. In the network list (List view), each access point will have a "Security" column, clearly indicating whether it's Open, WEP, WPA2, or WPA3. This is a great way to quickly assess the security of not only your own but also your neighbors' networks, allowing you to understand how noisy the airwaves are.
For macOS users, a great tool is the built-in, but hidden, "Wireless Network Diagnostics" utility. To launch it, hold down the [key] Option (Alt) and simultaneously click the Wi-Fi icon in the top menu bar. From the drop-down list, select "Open Wireless Network Diagnostics." After launching the utility (you can close the diagnostic window immediately), select "Window" -> "Scan" from the top menu. A list of all networks will appear with detailed descriptions, including the "Security" column, which indicates the security type.
⚠️ Attention: The use of Wi-Fi scanning software (especially in monitoring mode) may be regulated by law in some jurisdictions. Use these tools only to analyze your own networks or networks whose owners you have permission to analyze.
Also worth mentioning are mobile apps such as Fing or WiFi Man from Ubiquiti. They allow for in-depth network analysis directly from your phone. For example, Fing will show not only the security type but also a list of all devices on the network, which is useful for identifying intruders. These apps frequently update vendor databases, which helps identify equipment.
Recommendations for choosing the optimal level of protection
Once you've learned how to check your Wi-Fi security type and determined the current state of your network, the question arises of what to do with this information. If the check reveals the use of WEP or WPA (TKIP) protocols, or if the network isn't password-protected at all, immediate action is required. Modern internet traffic contains a huge amount of personal data, and neglecting basic security precautions can have serious consequences.
The optimal choice for the vast majority of users today is the mode WPA2-Personal (AES)This standard provides a high level of security and is supported by virtually all devices released in the last 10-15 years. The AES algorithm is reliable and time-tested. If all your devices are relatively new (released after 2018-2019) and your router supports WPA3, it is recommended to switch to it or to WPA2/WPA3 mixed mode for maximum security.
However, when choosing maximum security, don't forget about compatibility. Switching to pure WPA3 may cut off network connectivity for older printers, smart light bulbs, robot vacuum cleaners, and budget smartphones that simply don't support the new standard. In such cases, the mode Mixed (mixed) is a reasonable compromise, although it may theoretically be slightly less secure than pure WPA3 due to the need to support a backwards-compatible handshake process.
Remember that even the most advanced encryption protocol is powerless against a weak password. WPA2-AES security will be useless if the passphrase is "12345678" or a phone number. Passwords must be long (at least 12 characters) and contain upper- and lower-case letters, numbers, and special characters. Regularly changing your password and updating your router firmware are essential for maintaining the security of your home network.
Finally, it's worth noting that checking your router's security level isn't a one-time measure, but rather part of regular maintenance of your digital infrastructure. Check your router settings periodically, especially after a reset or firmware update, as sometimes the settings can revert to their factory, less secure values.
What to do if your router doesn't support WPA2 or WPA3?
If your equipment is so old that it doesn't support WPA2-AES, it's highly recommended to replace it. Modern routers are inexpensive, and using outdated equipment with weak security protocols puts all connected devices at risk. As a last resort, you can use the old router as an access point behind a newer, modern router, which will handle encryption.
Does security type affect internet speed?
Yes, it can. TKIP (used in WPA) artificially limits Wi-Fi speed to 54 Mbps, as it was originally designed for the 802.11g standard. Switching to AES (WPA2/WPA3) removes this limitation and allows you to reach the full speeds supported by your Wi-Fi standard (N, AC, AX).
Can a hacker hack a WPA2 network?
Theoretically, anything is possible, but in practice, brute-forcing WPA2-AES using a complex password (12+ characters, variable case-insensitive) would take thousands of years, even with powerful computing clusters. The real threat comes not from cracking the encryption, but from social engineering or viruses on users' devices.
