In today's digital world, a wireless network has become an integral part of any home or office infrastructure, providing access to the global network for dozens of devices simultaneously. However, few people consider the specific "lock" that protects transmitted data from prying eyes when connecting to an access point. Understanding How to find out the Wi-Fi security type, is the first and critical step in building a robust defense for your home or corporate perimeter against hacker attacks.
There are several main encryption protocols a router uses to encrypt traffic between the client and the access point. The choice of a specific algorithm directly affects how easily an attacker can intercept your passwords, banking information, or personal correspondence within range. In this article, we'll examine in detail methods for identifying the protocol used on various devices and operating systems.
Basic wireless network security protocols
Before moving on to the practical part of checking your router settings, it's important to clearly understand the differences between existing encryption standards, as their effectiveness varies dramatically. Historically, the first widely adopted standard was WEP (Wired Equivalent Privacy), which is now considered completely obsolete and can be hacked in minutes even by a non-professional using readily available software.
It was replaced by the standard WPA (Wi-Fi Protected Access), which used a temporary TKIP encryption key to enhance security, but it no longer meets modern data protection requirements. Today, the gold standard is WPA2 with the AES encryption algorithm, which provides reliable protection, but even it is gradually being replaced by the latest protocol WPA3, eliminating vulnerabilities of previous versions.
Below is a comparison table showing the key differences and reliability levels of the various protocols:
| Protocol | Year of implementation | Encryption algorithm | Security status |
|---|---|---|---|
| WEP | 1997 | RC4 | Critically vulnerable |
| WPA | 2003 | TKIP | Deprecated, not recommended |
| WPA2 | 2004 | AES (CCMP) | Reliable (standard) |
| WPA3 | 2018 | GCMP-256 | Maximum |
⚠️ Warning: If you find that your network is using WEP or WPA (TKIP), this means your data is not secure. You should immediately change your router settings to WPA2/WPA3.
Choosing the right protocol is a balance between compatibility with older equipment and security requirements. New devices support WPA3-Personal, which even protects against brute-force password guessing, but older devices may simply not see the network or refuse to connect when this mode is activated.
Checking the encryption type on Windows 10 and 11
The Windows operating system provides built-in tools for diagnosing your current connection, allowing you to quickly determine the security type currently in use. The easiest way to obtain this information is through the network settings graphical interface, which is accessible to anyone without specialized knowledge.
To get started, open the Start menu and go to Settings, then select Network & Internet. In the window that opens, find your active Wi-Fi connection and click the name of your network or the Properties button. In the list of options that opens, scroll down to the Security Type line, which will list the current protocol, for example, WPA2-Personal.
An alternative method for more advanced users is to use the command line, which provides a detailed report of all saved profiles. Open a terminal with administrator rights and enter the command netsh wlan show interfacesto see details of the current connection, including the authentication and encryption type.
⚠️ Note: The Windows Settings interface may vary slightly depending on the system update version. If you don't find the required entry, use the command prompt to obtain the correct information.
You can also get a complete list of all networks ever connected and their security settings by running the command netsh wlan show profiles, and then for a specific network: netsh wlan show profile name="Network_Name" key=clearIn the Security settings section, you will see the Cipher and Authentication fields.
Protocol identification on Android and iOS smartphones
Mobile devices also allow you to check security settings, although the path to this information may differ on different operating system versions. On devices running Android The process often varies depending on the casing manufacturer, but the general principle remains the same.
Go to Settings → Wi-Fi (or Connections). Click the gear icon next to the name of the connected network or tap the name itself. In the menu that opens, find the "Security" or "Encryption" section. It will indicate whether encryption is being used. WPA2, WPA3 or older standards.
☑️ Mobile Security Check
For iPhone or iPad owners (iOS) is less fortunate in terms of detail: Apple hides the technical details of the protocol in the standard interface, displaying only the connection status. However, if the device is connected to a WPA3-enabled network, some versions of iOS may display a corresponding icon next to the network name, or this information can be found in the console logs when a Mac is connected.
It's worth noting that modern smartphones automatically select the best available protocol when connecting. If the router supports WPA3, the phone will attempt to use it, but if that fails, it will fall back to WPA2. This is called mixed mode, which ensures compatibility but may reduce overall security.
Why does Android show different security types?
Different manufacturers (Samsung, Xiaomi, Pixel) interpret Android standards differently, so the menu may be called "Advanced," "Network Details," or hidden in the developer menu.
Analyzing settings via the router's web interface
The most reliable way to find out and, most importantly, change your security type is to log into your router's control panel. This method gives you full control over your wireless network configuration and allows you to see settings that may be hidden on client devices.
To log in, you need to open your browser and enter the gateway IP address (usually it is 192.168.0.1 or 192.168.1.1). After entering your login and password (often found on a sticker on the bottom of the device), go to the wireless network section. It may be called Wireless, Wi-Fi Settings or Wireless mode.
Inside the section, look for the subsection “Wireless Security” (Wireless Security). That's where the drop-down list with the current protection mode is located. Here you can see options like WPA-PSK, WPA2-PSK or combined mode WPA/WPA2-Personal.
⚠️ Note: Changing security settings will disconnect all connected devices from the network. You will need to re-enter the password on each device, so make sure you know the new access key.
It is recommended to select the mode WPA2-PSK (AES) as the most compatible and secure for most home networks. If your equipment is new and supports the standard, you can select exclusive mode. WPA3, but be aware of possible incompatibility with older printers or CCTV cameras.
Using specialized software for analysis
To thoroughly analyze the surrounding radio airwaves and determine the security types of all neighboring networks, professionals use specialized utilities. These programs scan frequencies and display detailed technical information about each detected access point.
One of the most popular free programs for Windows is inSSIDer or WiFi AnalyzerAfter running the scan, the app will generate a graph and list of networks, with the protocol listed in the "Security" or "Auth" column. This is useful if you want to assess how secure your neighbors' networks are or check if someone nearby has set up an access point with open WEP.
