In today's digital world, wireless connection security is becoming a critical aspect for every user. When connecting to a new network or checking the security of your home internet, the first step is to find out which one it is. encryption protocol is currently in use. This knowledge allows you to understand how vulnerable your data transmission is to attackers.
There are several ways to determine your security type: through your computer's operating system, smartphone settings, or the router's admin panel. Each method has its own unique features, but they all lead to the same goal: getting a complete picture of your network. channel security We'll review all available options so you can choose the most convenient one for your situation.
It is worth noting right away that old security standards, such as WEP, are considered completely outdated and insecure. Modern devices and providers have already migrated to more secure algorithms, but some older routers or public spaces still have weak protection. Understanding the differences between them will help you avoid potential threats.
⚠️ Attention: If you discover that your home network is using the WEP protocol or is open, change your router settings immediately. Using such networks in 2026 is like not having a lock on your front door.
Why do you need to know your WiFi encryption type?
The main reason for verification is to protect personal data from interception. When you use public networks In cafes or airports, attackers can exploit protocol vulnerabilities to steal passwords, correspondence, and banking information. Knowing the encryption type allows you to assess the risks before connecting.
In addition, knowledge of the current standard is necessary when setting up new equipment. If you have purchased modern router Although it supports Wi-Fi 6, connecting older devices that only support WPA may limit speed and security. Proper setup ensures maximum performance.
- 🔒 Data protection: Prevents hackers from stealing logins and passwords.
- 🚀 Operating speed: New protocols (WPA3) are faster and more stable than the old ones.
- 📱 Compatibility: Helps to understand why some gadgets do not see the network.
- 🏠 Access control: Allows you to limit the circle of people who have access to your traffic.
It is also important to consider that some smart home devices (smart home) may not support the latest security standards. In such cases, a compromise must be found between convenience and security by creating a guest network or using a separate frequency band.
Checking the protection type on Windows 10 and 11
Windows operating systems offer built-in tools for diagnosing wireless networks. This is the fastest way to obtain information without installing additional software. You don't need to be a system administrator to perform these steps.
To start, open the list of available networks by clicking the WiFi icon in the system tray (the usual corner of the screen). Hover over the desired network or right-click if you're already connected. In the menu that opens, select PropertiesIn the window that opens, find the line Security type (Security type). This is where the protocol used will be indicated, for example, WPA2-Personal.
If you want more detailed technical information, you can use the command line. This method is useful if the graphical interface doesn't display all the details or if the network is hidden.
netsh wlan show networks mode=bssidThis command will list all available networks and their base stations. Find your network name (SSID) in the list and look at the field AuthenticationThe exact protection type will be indicated there. Please note that administrator privileges may be required to run the command.

How to find out the security protocol on Android and iPhone
Mobile device owners can also quickly check their security settings. On smartphones Android The interface may differ depending on the manufacturer's shell, but the logic remains the same. Go to Settings → Wi-FiClick on the name of the connected network or the gear icon next to it. The "Security" section will indicate the type, for example, WPA/WPA2-Personal.
On devices Apple iPhone (iOS) the situation is similar. Go to Settings → Wi-FiClick on the blue information icon (i) to the right of the network name. Scroll down to "Security." Here you'll see the current standard, for example, WPA2 or WPA3.
It's important to understand that mobile operating systems often display simplified information. They may not display encryption (TKIP or AES) if it's not critical to the user. However, this is sufficient for a general security assessment.
- 📲 Android: Settings → Wi-Fi → Gear → Security.
- 🍎 iOS: Settings → Wi-Fi → (i) → Security.
- 👁️ Visualization: On iPhone, you may see a lock icon next to trusted networks.
Analyzing settings via the router's web interface
The most reliable and complete source of information is the router's administrative panel. Here you'll not only find out the type of protection, but also be able to change it if you're not satisfied. To log in, you'll need to know the device's IP address (usually 192.168.0.1 or 192.168.1.1) and administrator login and password.
After logging in, look for a section called Wireless, Wireless network or Wi-Fi SettingsThere will be a subsection within this section. Wireless Security or SecurityThis is where it is configured. protection mode (Security Mode). You will see a drop-down list with the current option selected.
⚠️ Attention: Interfaces of routers from different manufacturers (TP-Link, ASUS, Keenetic, MikroTik) vary greatly. Look for the keywords "Security," "Encryption," or "Encryption."
In this section, you can also usually configure the data encryption type (AES or TKIP). For maximum security, it is recommended to select the combination WPA2-PSK (AES) or WPA3-SAEAvoid Mixed Mode unless absolutely necessary, as it can reduce overall network performance.
| Protocol | Year of release | Security status | Recommendation |
|---|---|---|---|
| WEP | 1999 | Critically vulnerable | Do not use |
| WPA | 2003 | Outdated | Replace with WPA2 |
| WPA2 | 2004 | Reliable (standard) | Recommended |
| WPA3 | 2018 | Maximum | The best choice |
Don't forget to save your changes after changing the settings. The router may reboot, and all devices will need to be reconnected using the new password or settings.
What to do if you forgot your router password?
If you haven't changed the factory settings, try the default login and password listed on the sticker on the bottom of the device (often admin/admin). If the password has been changed and forgotten, you'll need to perform a factory reset by holding the button on the device for 10-15 seconds.
Using specialized PC utilities
For advanced users and network administrators, there are specialized programs that provide detailed technical information about the radio channel. Utilities such as WiFi Analyzer, Acrylic Wi-Fi Home or NetSpot allow you to see not only the type of protection, but also the signal level, channel loading and MAC addresses of access points.
Such programs are especially useful in multi-apartment buildings, where the airwaves are clogged with dozens of neighboring networks. They help select the least congested channel and ensure that your network is using the correct encryption standard. Some utilities can even display handshake details, which is important for security audits.
However, it's important to remember that using such tools to analyze other people's networks without permission may violate the law. Use them exclusively for diagnosing your own equipment and optimizing your personal network.
- 📡 Visualization: Real-time channel loading charts.
- 🔍 Details: Shows hidden SSIDs and BSSID technical parameters.
- 📊 Analytics: Helps to find "dead zones" and interference.
Most of these programs have free versions with basic functionality, which is sufficient for home use. Professional versions offer coverage heatmapping features.
Comparing Standards: WPA2 vs. WPA3
To date, the main de facto standard remains WPA2It's used in the vast majority of devices and provides reliable protection when using a complex password. However, it has known vulnerabilities, such as the KRACK attack, which theoretically allows data to be intercepted.
New standard WPA3, introduced by the Wi-Fi Alliance, addresses many of the shortcomings of its predecessor. It uses a more secure handshake mechanism (SAE – Simultaneous Authentication of Equals), which protects against brute-force attacks even on relatively simple passwords. WPA3 also improves security on open networks through individual data encryption.
Despite its advantages, the transition to WPA3 is slow. Many older devices (CCTV cameras, older smartphones, smart plugs) simply won't detect a network with this type of security. Therefore, routers often operate in mixed mode. WPA2/WPA3, ensuring compatibility.
⚠️ Attention: Technical specifications and protocol support vary by equipment manufacturer. Before purchasing a new router, check the specifications for WPA3 support if maximum security is important to you.
If your equipment supports WPA3, it makes sense to upgrade. This is especially important for users who store sensitive information on their devices or work remotely.
Does the type of protection affect internet speed?
The security type itself (WPA2/WPA3) has virtually no impact on speed in everyday use. However, using outdated TKIP encryption (instead of AES) can limit connection speeds to the standard 54 Mbps, even if the router supports higher speeds.
Frequently Asked Questions (FAQ)
Can WiFi security type affect internet speed?
Yes, it can, but indirectly. If you select compatibility with legacy devices (such as WEP or WPA with TKIP encryption), the speed may be limited to the 802.11g standard (up to 54 Mbps). Using WPA2/WPA3 with AES encryption allows you to utilize the full speed of modern standards (802.11n/ac/ax).
What should I do if my device won't connect to a WPA3 network?
Most likely, your device is too old and doesn't support the new standard. You need to enable mixed mode (WPA2/WPA3 Mixed) in your router settings or temporarily switch to WPA2 Personal. After connecting older devices, you can try reverting to WPA3 if your router can create a separate guest network for older devices.
How often should I change my password when using WPA2?
The WPA2 (AES) protocol itself is considered cryptographically strong. If you have a complex password (more than 12 characters, numbers, and special characters), you don't need to change it monthly. It's sufficient to change it once a year or if you suspect your password has been compromised.
Is it safe to use public WiFi with WPA2 security?
Using WPA2 in public places is better than using an open network, but it's not 100% guaranteed. An access point administrator or an attacker on the same network could still attempt to intercept your traffic. For complete security in public places, always use a VPN.
