In the age of total digitalization, a wireless network has become the central hub connecting all devices in a home or office. However, few people consider how exactly the data flow transmitted over the air from the router to your smartphone is protected. Understanding WiFi encryption type used on your network is a fundamental step in ensuring cybersecurity, as open or outdated protocols allow attackers to intercept passwords and personal information.
Modern security standards have come a long way from the primitive and easily hacked WEP to the advanced WPA3If you've never checked your router settings, there's a good chance your device isn't using the most secure traffic encryption method. In this article, we'll detail how to independently determine the current security protocol on various operating systems and why this knowledge is critical for protecting your data.
Why is it important to know network security protocol?
An encryption protocol is a set of rules and algorithms that your device and router use to negotiate how to encrypt transmitted data. If a weak algorithm is used, such as WEP or earlier versions WPAA hacker only needs a few minutes and a minimal set of tools to gain access to your network. This allows access not only to internet traffic but also to local resources such as printers, network storage, and security cameras.
Furthermore, knowing the current security status helps diagnose speed issues. Old protocols often prevent the use of modern frequency ranges and wide channels, which artificially limits connection speed. If your router supports Wi-Fi 6, but configured to work with legacy clients via WPA/TKIP, you will not be able to unlock the potential of the equipment.
⚠️ Warning: Using the WEP or WPA protocol (without the numbers 2 or 3) makes your network vulnerable to automated attacks that can be carried out even by an inexperienced user using scripts available on the Internet.
It's also worth considering that some modern devices, especially those in the smart home ecosystem, may simply refuse to connect to networks with low security levels. Electronics manufacturers are gradually implementing minimum security requirements, blocking connections to unsecured or weakly secured access points.
Determining the encryption type on Windows 10 and 11
The Windows operating system provides built-in and fairly simple tools for viewing connection details. The fastest way to find out security type — Use the network connections graphical interface. This method doesn't require any additional software and is accessible to any user.
To begin, open the Start menu and go to "Settings," then select "Network & Internet." In the window that opens, find the "Properties" link under the name of your active Wi-Fi network. In the list of options that opens, scroll down to "Security Type." This is where the protocol used will be listed, for example, WPA2-Personal or WPA3-Personal.
An alternative, more professional method involves using the command line. This method provides more technically accurate information and can be useful if the graphical interface is not working correctly. Open the command prompt (cmd) as administrator and enter the command:
netsh wlan show interfacesIn the command output, look for the line "Authentication." The current protocol will be listed next to it. This method is especially useful for system administrators conducting security audits of corporate networks remotely.
- 🔍 The graphical interface is convenient for quick checking by ordinary users without in-depth knowledge.
- 💻 The command line provides more detailed technical information about the interface state.
- 🛡️ Checking through the Network and Sharing Center also allows you to see the connection status and encryption type in real time.
How to check encryption on Android and iOS
Mobile devices are the most frequent users of wireless networks, so knowing how to check the security of a connection on a smartphone is crucial. However, mobile operating systems, unlike desktop ones, often hide detailed technical information in favor of a minimalist interface.
On devices with the operating system Android The situation depends on the OS version and the manufacturer's shell. In most cases, if you go to Settings → Wi-Fi and click on the name of the connected network (or the gear icon next to it) to see detailed information. Look for the "Security" or "Encryption" field. It will indicate whether it's using WPA2/WPA3-Personal.
Hidden Android Settings
On some Xiaomi and Samsung smartphones, detailed information about the encryption type is hidden in the "Advanced" menu or becomes available only after scanning the network's QR code generated by the system.
For device owners Apple (iPhone, iPad) are less fortunate in terms of system transparency. Using standard iOS tools, it's impossible to see the encryption type of a connected network unless you're a developer with access to the logs or using special configuration profiles. Apple operates on the principle that if you know the password and are connected, you're connected to a trusted network.
However, you can indirectly check security by attempting to connect to the network from a known device. If the router is configured in compatibility mode, it may offer older protocols. For a more accurate check on iOS, it's best to use third-party Wi-Fi analyzer apps available in the App Store, although their functionality may be limited compared to their Android counterparts.
- 📱 On Android, the information is usually available in the connection details without root access.
- 🍏 iOS hides the encryption type in the standard interface, requiring third-party solutions to analyze it.
- 🔐 Scanner apps on Android can show not only the encryption type, but also the signal strength and channel.
Diagnostics via the router's web interface
The most reliable way to find out the encryption type is to look under the hood of the router itself. The router's web interface is the source of truth, as it's where all wireless network settings are configured. To log in, you'll need the device's IP address (often 192.168.0.1 or 192.168.1.1) and administrator login and password.
After authorization, you need to find the section responsible for the wireless network. It may be called Wireless, Wi-Fi, Wireless mode or WLAN. Within this section, look for the “Security” subsection (Security) or "Security Settings". This is where the Version (protocol version) and Encryption (encryption method).
☑️ Router security check
It is important to note that interfaces vary greatly between different manufacturers. TP-Link It's usually the "Wireless" -> "Wireless Security" tab. ASUS - "Wireless Network" menu -> "WPA Encryption Method" tab. MikroTik settings are scattered throughout the section Wireless on the menu Security Profile.
⚠️ Note: Router interfaces are constantly being updated. If you can't find the options listed, check the official manual for your model or look for screenshots of the interface for your firmware version, as menu locations may change.
Here you can not only view but also change the encryption type to a more secure one. However, keep in mind that changing the settings will disconnect all devices, requiring you to reconnect them and re-enter the password.
Comparison of encryption standards: WEP, WPA, WPA2, WPA3
To understand how secure your network is, you need to understand the acronyms you'll see in your settings. The history of wireless security has seen several key stages, each offering a new level of protection but also introducing new vulnerabilities.
WEP (Wired Equivalent Privacy) is the oldest standard, dating back to 1997. It uses static encryption keys, which are extremely easy to break. Today, using WEP is considered completely unacceptable.
WPA (Wi-Fi Protected Access) was created as a temporary solution to replace WEP. It uses the protocol TKIP for encryption. While it's better than WEP, it also has known vulnerabilities and doesn't support the high speeds of modern Wi-Fi standards.
WPA2 (Wi-Fi Protected Access 2) is the current industry standard, mandatory for all devices bearing the Wi-Fi logo since 2006. It uses a secure algorithm AES (Advanced Encryption Standard), which is used even in government agencies to protect classified information.
WPA3 — the latest standard, introduced in 2018. It addresses many of the shortcomings of WPA2, such as vulnerability to brute-force attacks, and provides protection even on open networks through personalized encryption.
| Protocol | Year of release | Encryption algorithm | Security level | Status |
|---|---|---|---|---|
| WEP | 1997 | RC4 | Critically low | Deprecated (Do not use) |
| WPA | 2003 | TKIP | Short | Outdated |
| WPA2 | 2004 | AES (CCMP) | High | Recommended minimum |
| WPA3 | 2018 | AES-GCMP | Very tall | The best choice |
Technical Details: AES vs. TKIP
Often in the router settings you can find combined options, for example, WPA/WPA2 - Mixed or a choice between AES And TKIPUnderstanding the difference between these two encryption algorithms will help you configure your network correctly. TKIP (Temporal Key Integrity Protocol) was developed as a temporary replacement for WEP and uses the same mechanisms, making it vulnerable.
AES (Advanced Encryption Standard) is a block cipher considered one of the most secure in the world. It's not only more secure, but also faster, as AES computations are often performed in hardware on the router's processor, while TKIP overloads the processor with software calculations, which can reduce speed Internet, especially on older routers.
If your router offers a choice of "WPA2-PSK (AES)" or "WPA2-PSK (TKIP)", always choose the option with AESMixed Mode, which supports both types, may only be necessary if you have very old devices (manufactured before 2006) that are unable to handle AES. However, the presence of such "dinosaurs" on the network compromises the security of all other devices.
- ⚡ AES provides higher data transfer speeds thanks to hardware acceleration.
- 🔒 TKIP has known vulnerabilities and is not recommended for use in modern networks.
- 📉 Enabling Compatibility Mode (Mixed) may reduce overall network performance to the level of the slowest protocol.
Frequently Asked Questions (FAQ)
Can encryption type affect internet speed?
Yes, it can. Using an outdated protocol. TKIP instead of AES Often limits wireless connection speed to the 802.11g standard (up to 54 Mbps), even if your router supports 802.11n or ac. Furthermore, TKIP software encryption places additional load on the router's processor, which can cause lag.
What if my older devices don't connect to WPA2/WPA3?
These devices likely have very old Wi-Fi modules that don't support modern security standards. As a temporary solution, you can create a guest network on a router with lower security requirements, but isolated from the main network. However, it's best to consider replacing the outdated equipment.
How hard is it to crack WPA2?
The WPA2 protocol itself with AES encryption is virtually impossible to crack without knowing the password. However, attackers use brute-force attacks on the password itself. If your password is simple (for example, "12345678" or your date of birth), it will be guessed quickly. A complex password of 12+ characters, including letters and numbers, makes cracking WPA2 virtually impossible.
Do I need to change the settings if I have WPA2-Personal?
If an encryption method is used AES If a strong password is set, there's no urgent need to change the settings. WPA2 is still considered a reliable standard. Switching to WPA3 is desirable, but not critical for the average home user right now.
Where can I find my Wi-Fi password if I forgot it but am connected to the network?
On Windows, you can view the saved password in the wireless network properties under the "Security" tab by checking the "Show characters" box. On Android, this often requires root access or the "Share QR Code" feature, which may hide the password but allow it to be scanned by another device.
