How to Check What Wi-Fi Encryption You're Using: A Complete Guide

Have you ever wondered how secure your home Wi-Fi network is? In an age where hackers can sniff your password in minutes, knowing your router's encryption type isn't just a technical detail, it's a matter of personal data security. From outdated WEP, which can be hacked in seconds, to a modern one WPA3 with military-grade protection, the difference is colossal.

This article will help you Accurately determine the encryption protocol of your Wi-Fi network in 5 minutes, without resorting to the services of IT specialists. We will consider methods for all devices: from laptops to Windows 11 before smartphones on Android 14We'll also show you how to check your settings directly in the router control panel. You'll learn not only how to view your current protection type but also how to update it if it's out of date.

Why is it important to know your Wi-Fi encryption type?

The type of encryption determines how easily an attacker can connect to your network or intercept transmitted data. Here's why it's critical:

• 🔓 WEP (Wired Equivalent Privacy) - an outdated protocol from 1999, which is now being hacked 3-5 minutes using free tools like Aircrack-ngUsing it is equivalent to not having a password.
• 🛡️ WPA2 (Wi-Fi Protected Access 2) — a standard since 2004 that is still considered safe when configured correctly (used AES-CCMP, and not TKIP).
• 🔐 WPA3 — the latest protocol (2018), eliminating the vulnerabilities of WPA2 (for example, attacks KRACK) and adding protection against brute-force attacks.

According to the study Kaspersky for 2023, 38% of home networks still use WEP or WPA with TKIP, making them an easy target for cybercriminals. Even if your password is complex, the outdated protocol renders it ineffective.

⚠️ Attention: If your router only supports WEP, it is necessary urgently replace — no password will protect you from hacking. Most modern devices (smartphones, laptops) won't even be able to connect to such a network.

Method 1: Checking through the router settings (the most accurate method)

This method is 100% accurate because you're viewing the settings directly from the source. These instructions are suitable for all router models: TP-Link, ASUS, Keenetic, MikroTik and others.

1. Connect to the Wi-Fi network whose encryption type you want to know.

2. Open your browser and enter your router's IP address in the address bar. This is usually: 192.168.0.1, 192.168.1.1 or 192.168.8.1 (The exact address is indicated on the sticker on the back of the device).

3. Enter your username and password to log in. By default, this is often admin/admin or admin/password (see sticker).

4. Go to the wireless network section. The path may vary:

   • 📡 TP-Link: Wireless → Wireless Settings
   • 🖧 ASUS: Wireless Network → General
   • 🌐 Keenetic: Wi-Fi → Hotspot

Find the field "Security Mode", "Encryption" or "Safety"The current protocol will be listed there: WPA2-PSK (AES), WPA/WPA2 Mixed, WEP etc.

Find the IP address using the command ipconfig (Windows) or ifconfig (Mac/Linux)|Try resetting the router using the button Reset (hold for 10 seconds)|Check if you are connected to this router's network|Use a different browser (eg. Firefox instead of Chrome)

-->

If specified in the settings WPA2-PSK [AES] — your network is securely protected. If you see WEP or WPA-PSK [TKIP], it is necessary to urgently update the protocol (instructions will be below).

⚠️ Attention: On some routers (for example, older models D-Link) may only display "WPA2" without specifying the encryption type (AES/TKIP). In this case, check with another device (method 2 or 3).

Method 2: View encryption type on Windows 10/11

If you don't have access to your router (for example, you're connected to a public network or guest Wi-Fi), you can find out the encryption type directly from your computer.

1. Click Win + R, enter ncpa.cpl and press EnterThe "Network Connections" window will open.

2. Find your wireless connection (usually "Wireless Network" or "Wi-Fi"), right-click on it and select "State".

3. In the window that opens, click the button Wireless Network Properties.

4. Go to the tab "Safety"In the field Security Type the protocol will be indicated, and in the field Encryption Type — method (AES or TKIP).

If the "Encryption Type" field is set to TKIP, your network is vulnerable even when using WPA2. The best option is AES.

Method 3: Determine the protocol on an Android smartphone

On phones with Android 10 and newer, you can find out the encryption type without root rights, but the functionality depends on the manufacturer. For example, on Samsung Galaxy And Xiaomi information is displayed differently.

For most Android devices:

1. Open "Settings" → "Wi-Fi".

2. Tap on your network name (do not reconnect!).

3. Look at the field "Safety" or "Security"The protocol will be indicated there.

For Xiaomi smartphones (MIUI):

1. Go to Settings → Wi-Fi → Advanced → Connection history.

2. Select your network. The encryption type will be listed in the section "Safety".

For Samsung (One UI):

1. Open Settings → Connections → Wi-Fi.

2. Click on the gear next to the network name.

3. Scroll down to the section "Safety".

On iPhone (iOS) It's impossible to find out the encryption type without jailbreaking—Apple hides this information "to simplify the interface." iPhone owners will have to use method 1 (via the router) or method 4 (via the command line).

Method 4: Checking via the command line (for advanced users)

This method works on Windows, MacOS And Linux, but requires knowledge of commands. It's useful if you can't access your router's control panel or want to check the network you're currently connected to.

For Windows:

netsh wlan show interfaces

Look for the line Security Type in the conclusion.

For MacOS/Linux:

sudo airport -I | grep"link auth"

or (if airport not installed):

iwconfig

The output will contain a line like this: IEEE 802.11i/WPA2.

This method provides minimal information (usually only WPA2 or WPA3), but does not show the encryption type (AES/TKIP). For detailed analysis, it is better to use Wireshark or specialized utilities like inSSIDer.

How to find out if someone else's network is encrypted (legally)?

This is only possible if the network doesn't hide its SSID. Use apps like WiFi Analyzer (Android) or NetSpot (Mac/Windows) They show open information about networks, including security protocols. However, attempting to connect to someone else's network without permission is a violation of the law (Article 272 of the Criminal Code of the Russian Federation).

Method 5: Using third-party applications

If standard methods fail, you can use specialized programs. They will not only show the encryption type but also analyze signal strength, channels, and other network parameters.

• 🖥️ For Windows/Mac:
  • 📊 NetSpot - shows the security protocol, signal level and channel occupancy.
  • 🔍 inSSIDer — a professional tool for analyzing Wi-Fi networks (the paid version reveals more data).
• 📱 For Android:
  • 📶 WiFi Analyzer (from VREM Software) is free and easy to use.
  • 🛡️ Fing — determines the protocol and checks the network for vulnerabilities.

Example of a report in NetSpot:

SSID: MyHomeWiFi
BSSID: AA:BB:CC:DD:EE:FF
Security: WPA2-PSK (AES)
Channel: 6 (2.4 GHz)
Signal: -55 dBm

⚠️ Note: Some applications (eg. Wifi WPS WPA Tester) market themselves as security testing tools, but are actually used to hack networks. Their installation can be seen as preparation for cybercrime.

How to update your Wi-Fi encryption if it's out of date

If you discover that your router is using WEP or WPA with TKIP, you need to update the settings immediately. Here are the step-by-step instructions:

1. Log in to your router's control panel (see Method 1).

2. Go to your wireless network settings (usually Wireless Settings or Wi-Fi).

3. Find the field "Security Mode" or "Encryption" and select:

   • 🔒 WPA2-PSK (recommended for most devices)
   • 🔒 WPA2/WPA3-PSK (if the router supports WPA3)

In the field "Encryption" or "Cipher Type" select AES (not TKIP!).

Create a new password (at least 12 characters, including numbers and special characters).

Save the settings and reconnect all devices.

If your router does not support WPA2/AES, it will need to be replaced. Modern models (e.g., TP-Link Archer AX6000 or ASUS RT-AX88U) support WPA3 and provide corporate network level security.

Common mistakes and how to avoid them

When checking or changing encryption, users often encounter typical problems:

• 🔄 "After switching to WPA3, some devices won't connect." - this means that they do not support the new protocol. Solution: use the mode WPA2/WPA3 Transition Mode (if available in the router settings).
• 🔌 "I can't log into my router control panel." - try resetting the settings with the button Reset (Hold for 10-15 seconds). After the reset, the login/password will be default (see the sticker on the router).
• 📶 "The network disappeared after the encryption was changed." - check that you have saved the settings ("Apply" or "Save"). Sometimes rebooting the router helps.
• 🔑 "I forgot my Wi-Fi password after changing encryption." — you can see the new password in the router settings (section Wireless Security) or reset the router to factory settings.

If your internet speed has slowed down after a protocol update, the encryption isn't the problem. A congested Wi-Fi channel is likely to blame. Use apps like WiFi Analyzerto find a free channel and change it in the router settings.

FAQ: Answers to Frequently Asked Questions

Is it possible to hack a WPA2-AES network?

Theoretically yes, but in practice it is extremely difficult. Attack KRACK (2017) exploited a vulnerability in the WPA2 protocol, but it was fixed in updates for most devices. The main thing is to use strong password (at least 12 characters with mixed cases and special characters) and regularly update the router firmware.

What is considered a strong password for Wi-Fi?

A good password should:

• 🔢 Be long 12+ characters
• 🔤 Contain letters different registers (A-z)
• 🔢 Turn on numbers And special characters (!@#$%^&*)
• 🚫 Not be a dictionary word or an easily guessed sequence (e.g. 12345678 or qwerty)

Example of a strong password: kL9#!pR*2mQ7@xY

Why does my network show WPA2, but devices connect as WPA?

This happens if the mode is selected in the router settings WPA/WPA2 Mixed (or WPA Auto). In this case, the router automatically selects a protocol based on the device's capabilities. For example, an old printer might connect via WPA, while a smartphone might connect via WPA2. It is recommended to disable WPA support., leaving only WPA2 or WPA3.

My router doesn't support WPA3. Should I upgrade?

If your router supports WPA2-AES and you don't have devices older than 2010, there's no immediate need to replace it. However, WPA3 from:

• 🛡️ Dictionary attack (brute force)
• 🔍 Eavesdropping on traffic (even if the password is known)
• 🕵️‍♂️ Attacks through protocol vulnerabilities (for example, Dragonblood for WPA3 already fixed)

If you store important data at home (for example, using banking apps), upgrading to WPA3 makes sense.

How do I check if my device supports WPA3?

List of devices that support WPA3:

• 💻 Laptops/PCs: All devices with Windows 10 1903+ or MacOS 10.15+.
• 📱 Smartphones: iPhone 7 and newer, Android 10+ (but requires hardware support from the Wi-Fi chip).
• 🖨️ Smart technology: Most devices after 2020 (eg. Samsung SmartThings, Google Nest).

To find out for sure, try connecting to a WPA3 network. If your device doesn't see the network or returns an error, it's not supported.
