A modern wireless network requires reliable security, but few people think about what security protocol is currently in use. Wi-Fi encryption type — This is a fundamental parameter that determines how easily an attacker can intercept your data or gain access to the internet. If you're still using the default settings left by your ISP or router manufacturer, there's a risk your network is vulnerable to attack.
In this article, we'll look at how to determine your current security method, why older standards like WEP pose a threat, and how to migrate to a more modern one. WPA3Understanding these differences is essential for every user who values their digital privacy and connection speed.
Basic types of wireless network encryption
The history of Wi-Fi development has seen several stages of security protocol evolution, each with its own unique characteristics and vulnerabilities. The very first standard was WEP (Wired Equivalent Privacy), which was introduced back in 1997. Despite its ambitious name, which implied security equivalent to a wired network, this protocol turned out to be extremely weak and was cracked almost immediately after its widespread adoption.
He was replaced by WPA (Wi-Fi Protected Access), which was intended to be a temporary solution until the 802.11i standard was finally adopted. However, it also contained vulnerabilities related to the TKIP algorithm, which was eventually deemed insecure. Today, the use of either method is considered insecure and is not recommended in any situation.
⚠️ Attention: If your router only supports WEP or WPA (TKIP), it needs to be replaced. These protocols offer no real data security and can be hacked in minutes, even by an inexperienced user, using automated scripts.The modern gold standard is WPA2, which uses a strong encryption algorithm AES (Advanced Encryption Standard). This protocol provides a balance between high data transfer speeds and robust security. It is already being implemented in the latest devices. WPA3, which eliminates handshake vulnerabilities and protects even when using weak passwords.

The Windows operating system provides built-in tools for viewing detailed information about your current connection. You don't need to install third-party software to get basic security information. The easiest way is to use the graphical interface in the Network Control Panel.
To do this, press the key combination
Win + R, enter the commandncpa.cpland press Enter. In the window that opens, find your wireless connection, right-click it, and select "Status." Then click "Wireless Network Properties."In the window that opens, go to the "Security" tab. Here, in the "Encryption Type" field, the currently used protocol will be displayed. Typically, it will say AES or TKIP, which corresponds to the WPA2 or WPA standards, respectively.
☑️ Security check in Windows
Completed: 0 / 5An alternative method for advanced users is to use the command line. This method provides more technical information and can be useful if the graphical interface is not working correctly or is blocked by administrative policies.
Open Command Prompt (cmd) as administrator and enter the following command:
netsh wlan show interfacesIn the command output, look for the line "Authentication." This will indicate the protocol being used, for example, WPA2-Personal or WPA3-Enterprise. Also pay attention to the "Cipher" line, where the algorithm used will be indicated, most often CCMP (for AES) or TKIP.
Protocol detection on macOS and mobile devices
Apple ecosystem users can also easily check their network security settings, although the macOS interface periodically changes with the release of new operating system versions. In current versions of macOS, the process is as follows.
Hold down the key
Option(Alt) on your keyboard and click the Wi-Fi icon in the menu bar. In the drop-down list, find the line "Security Type." This will display the protocol name, for example, WPA2 Personal or WPA3 Personal.On mobile devices running Android And iOS This information is also available, but often hidden in the deeper layers menu. On iPhone, go to "Settings" → "Wi-Fi," tap the blue "i" icon next to your network name. Scroll down to the "Security" section, where the encryption type will be listed.
On Android, the path may vary depending on the manufacturer's operating system (MIUI, OneUI, ColorOS), but the general logic remains the same: Settings → Wi-Fi → Gear icon or network name → Advanced. Look for the "Security" or "Encryption" field.
⚠️ Attention: Mobile operating system interfaces are frequently updated. If you can't find the information you're looking for, try using third-party Wi-Fi analyzer apps from official stores that read system data.Why might the encryption type not be displayed on my phone?
Some smartphone manufacturers hide technical connection details in the standard interface to avoid overwhelming the user. In such cases, the system only displays the "Connected" or "Secure" status without providing any protocol details. To obtain complete information on Android, you can use engineer mode or ADB commands, but this requires some skill.
Analyzing settings via the router's web interface
The most reliable way to find out and, most importantly, change the encryption type is to access the router's settings. This method gives you complete control over the network configuration and allows you to see not only the current status but also available upgrade options.
To log in, enter the router's IP address (usually
192.168.0.1,192.168.1.1or192.168.31.1). After authorization (the login and password are often indicated 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".Within this section, look for the "Wireless Security" subsection. Here you'll see a drop-down list with available modes. This is where you configure settings. WPA2-PSK or WPA3.
Protocol Encryption algorithm Security status Recommendation WEP RC4 Critically low Replace immediately WPA (TKIP) TKIP Short Replace with WPA2 WPA2 (AES) AES (CCMP) High Recommended standard WPA3 GCMP-256 Maximum Use if supported When changing settings, you'll have to re-enter your password on each device. This is normal security behavior.
Technical differences between encryption algorithms
Understanding the difference between algorithms TKIP And AES helps us understand the importance of upgrading to modern standards. TKIP (Temporal Key Integrity Protocol) was developed as a workaround to fix the weaknesses of WEP, allowing older equipment to be used with the new security.
However, TKIP has a speed limitation: it limits network throughput to 54 Mbps, even if your router supports gigabit speeds. This is because the protocol requires significant computing resources to generate keys and is not optimized for modern data transfer speeds.
Algorithm AES (Advanced Encryption Standard) is an encryption standard approved by the US government to protect classified information. In the context of Wi-Fi, it is used in conjunction with the protocol CCMPAES is not only more secure, but also operates on the router's processor hardware, eliminating any speed bottlenecks.
If you see the "WPA/WPA2 Mixed Mode" option in the settings, it means the router is attempting to be compatible with all devices by broadcasting both signal types. This reduces the overall network security to the weakest link level.
⚠️ Attention: Using mixed mode (WPA/WPA2) can open the door to downgrade attacks, where an attacker forces your device to switch to the less secure WPA protocol to intercept data.Compatibility issues and the transition to WPA3
Transition to WPA3 This is a logical step to improve security, but it comes with compatibility issues for older equipment. Devices manufactured more than 5-7 years ago are physically unable to support this encryption standard.
If you enable "WPA3 Only" mode, all older devices will simply stop seeing your network or be unable to connect. In such situations, routers offer a fallback mode. WPA2/WPA3 Transitional, which allows both types of protection to operate simultaneously.
However, even in transitional mode, there are risks. Some smart devices (light bulbs, sockets, old CCTV cameras) may behave incorrectly in the presence of WPA3, even if they connect using WPA2. They may constantly lose connection or require reauthorization.
To check if your equipment supports WPA3, you can refer to the manufacturer's specifications or update your router's firmware. Manufacturers often add WPA3 support through software updates for models released in the last three to four years.
It's also important to distinguish between personal (Personal/PSK) and enterprise (Enterprise) protocol versions. Personal is used for home use, where the key is a password. Enterprise requires an authorization server (RADIUS) and is used in offices for individual user access.
What should I do if I lose internet access after changing encryption?
First, check that the password on your device is entered correctly. If the password is correct, try forgetting the network on your device and reconnecting. If the issue persists, your device may not support the selected encryption type (for example, an older laptop and WPA3). In this case, change your router back to mixed mode or WPA2 (AES).
Does encryption type affect Wi-Fi speed?
Yes, it does. Using the legacy TKIP limits speeds to 54 Mbps. Switching to AES (WPA2/WPA3) removes this limitation. Furthermore, some modern Wi-Fi features, such as Wi-Fi 6 (802.11ax), require WPA3 to operate at maximum speeds.
Is it possible to hack WPA2?
In theory, yes, but in practice, it's extremely difficult. An attack is possible through the KRACK vulnerability or by brute-forcing the password. If you use a complex password (more than 12 characters, with numbers and special characters), cracking WPA2-AES would take thousands of years, even on powerful clusters. A weak password is the biggest security hole.
