In today's digital world, wireless security is a critical aspect that's often overlooked until problems arise. When connecting to a home network or checking your router settings, knowing the encryption protocol used is key to protecting your personal data from prying eyes. Network protection type Determines how difficult it is for an attacker to intercept your traffic or gain access to devices on your local network.
Many users are unaware that their router may be running on outdated security standards that were cracked several years ago. Understanding the difference between WPA2, WPA3 and outdated WEP Allows you to make informed decisions when configuring your equipment. In this article, we'll cover in detail how to check the current encryption status using various methods and what to do if a vulnerability is detected.
The verification process does not require in-depth knowledge of network technologies and can be completed in just a couple of minutes using standard operating system tools. The most reliable method is to log into the router's web interface, which displays complete and accurate information about the wireless module's configuration. However, there are also faster ways through the interface of Windows, macOS or mobile devices, which we will also consider.
Determine the encryption type through Windows settings
The Windows operating system provides a convenient built-in tool for viewing active connection details. This method is ideal for a quick check without having to log into the router's administrative panel. To obtain the necessary information, open the list of available networks or go to the settings of an existing connection.
Click on the Wi-Fi icon in the tray (lower right corner of the screen) and select Properties active network. In the window that opens, scroll down to the "Properties" section, where you'll see "Security Type." Here you'll see the abbreviation for the protocol being used, for example, WPA2-Personal or WPA3-SAE.
An alternative method involves using the command line, which can be useful for system administrators or when working with remote desktops. Open a terminal and enter the command netsh wlan show interfacesIn the command output, find the line "Authentication," which indicates the current authorization method.
It's worth noting that if Windows displays the security type as "Open" or "No Security," this means that the transmitted data is not encrypted and can easily be intercepted by any device within range of the access point.
⚠️ Attention: If your network properties show "WEP," change your router settings immediately. This encryption standard is considered completely obsolete and can be cracked in minutes, even by a novice.
For a more detailed analysis, you can use the utility netsh wlan show profiles name="Network_Name" key=clear, which will show the saved security settings, including the encryption type and even the cleartext password (in the "Key Content" field).
Checking connection security on macOS and Linux
Apple computer users can also quickly find out which security protocol their Wi-Fi connection uses. The macOS interface is slightly different from Windows, but the information is available in a similar location. Hold down the Option on your keyboard and click on the Wi-Fi icon in the menu bar.
In the drop-down list, you'll see detailed technical information about the current connection. Look for the "Security" line, which will indicate the security type, such as: WPA2 Personal or WPA3 TransitionalThis is the fastest way to get data without opening system settings.
In Linux-based operating systems such as Ubuntu or Debian, information can be accessed through a graphical interface or terminal. In the GNOME desktop environment, simply click the network icon, select "Network Settings," and go to the Wi-Fi section, where the connection's security method will be listed in the connection properties.
For command line lovers, there is a powerful utility in Linux. nmcli. Enter the command nmcli -f active,ssid,security dev wifito see a list of active networks and the encryption protocols they use.
If you are using a distribution with a minimalistic interface, the command iwconfig or iw dev wlan0 link can also provide information about encryption keys, although interpreting the output may require some experience.
Analyzing settings via the router's web interface
The most reliable source of information about your network configuration is the router itself. Accessing the control panel allows you to not only view the current security type but also change it to a more secure one. To do this, you need to know the gateway IP address, which is usually located on a sticker on the bottom of the device (often 192.168.0.1 or 192.168.1.1).
After entering the address in the browser and logging in (the login and password are often also on the sticker if you haven't changed them), you need to find the section related to the wireless network. It may be called Wireless, Wi-Fi, Wireless mode or WLAN.
Within this section, look for the "Security" subsection (Security) or "Wireless Network Settings." This is where you'll find the drop-down list for selecting the security version. Here you'll see whether the mode is activated. WPA3, mixed mode WPA2/WPA3 or old WPA.
The advantage of this method is that you can see the settings for each frequency band (2.4 GHz and 5 GHz) separately, as some routers may have different security settings for them.
☑️ Checking router settings
Don't forget to save your changes if you decide to update the protocol by clicking the button Save or ApplyAfter this, all devices will require you to re-enter the password to connect.
⚠️ Attention: Router interfaces from different manufacturers (Asus, TP-Link, Keenetic, MikroTik) can vary significantly. If you can't find the required option, consult the official documentation for your specific model.
Using mobile applications for Android and iOS
Smartphones are the primary devices for internet access, so it's important to know how to check network security directly from your phone. On Android, the process may vary depending on the OS version and manufacturer's user interface, but the general principle is the same.
Go to Settings → Wi-Fi (or "Connections"). Click on the name of the active network or the gear icon next to it. In the menu that opens, find "Security" or "Security Type." This will indicate the standard used, for example, WPA/WPA2-Personal.
On Apple devices (iPhone, iPad), you can't see the encryption type of the active network in the Wi-Fi settings using standard tools—iOS hides this technical detail from the average user. However, you can use third-party apps from the App Store, such as AirPort Utility (from Apple) or Fing.
Application Fing Allows you to scan your network and displays detailed information about each access point, including its security type. This is a great way to check not only your own network but also your neighbors' to assess the overall security level in your home.
On Android there are also specialized snails like WiFi Analyzer, which graphically display the channels and encryption types of all surrounding networks, helping you choose the least congested and most secure channel.
Why is the security type hidden on the iPhone?
Apple adheres to a minimalist interface philosophy, believing that the average user doesn't need to understand the technical details of protocols as long as the connection works. However, this can be inconvenient for troubleshooting problems.
Comparison of security standards: WEP, WPA and their versions
Understanding the differences between security standards is essential for properly configuring equipment. Each has its own characteristics, vulnerabilities, and release year. Below is a table comparing the key characteristics of popular protocols.
| Protocol | Year of release | Security level | Status |
|---|---|---|---|
| WEP | 1997 | Critically low | Outdated (hacked) |
| WPA | 2003 | Short | Not recommended |
| WPA2 | 2004 | High | Standard (recommended) |
| WPA3 | 2018 | Very tall | New standard |
WEP (Wired Equivalent Privacy) is the very first standard to use static encryption keys. Its vulnerabilities allow passwords to be recovered in minutes using software like Aircrack-ngUsing this protocol today is equivalent to having no password.
WPA2 (Wi-Fi Protected Access 2) uses an algorithm AES for encryption, making it a reliable choice for most home networks. However, it is vulnerable to attacks like KRACK, although patches for this have been released for most devices for a long time.
WPA3 — a current standard that addresses many of the shortcomings of previous versions. It uses personalized data encryption and protects against brute-force password guessing, making dictionary attacks virtually useless.
When selecting a router mode, you'll often see the "Mixed" or "Auto" option. This allows older devices to connect via WPA2 while newer devices use WPA3. However, having older protocols in mixed mode theoretically reduces overall network security.
Frequently Asked Questions (FAQ)
What should I do if my router doesn't support WPA3?
There is no need to panic. WPA2 with encryption AES is still considered a secure standard, as long as you use a complex password (at least 12 characters, including letters and numbers). Update your router firmware regularly to patch known vulnerabilities.
Can the type of protection affect internet speed?
The impact is minimal and unnoticeable under normal conditions. However, the transition from TKIP (old encryption method for WPA) on AES can significantly increase speed, as TKIP artificially limits speed to 54 Mbps on some devices.
How can I find out who is connected to my network, knowing the security type?
The security type itself doesn't show connected devices. To do this, you need to log into the router's web interface and find the section Attached Devices, Client List or Client listAll active MAC addresses are displayed there.
Is it safe to use public Wi-Fi without a password?
No, this is extremely dangerous. Open networks do not encrypt traffic, allowing attackers to intercept your logins, passwords, and correspondence. Use a VPN when connecting to a public hotspot.
Do I need to change my password if I changed the security type from WPA to WPA2?
Yes, this is a good practice. Changing the security protocol requires re-entering the password on all devices anyway. Use this opportunity to set a new, more complex access key.
