Check Wi-Fi Network Security Type

Card No. 06·40313 · Updated · Standard formula, shown below

To check your Wi-Fi network security type, open your device’s Wi-Fi settings, view the network details for the connected network, and look for the security or encryption field—it will show something like WEP, WPA, WPA2, or WPA3. This article explains how to find that information on Windows, macOS, Android, iOS, and in router settings, plus what each security type means and how to improve your network’s safety.

Why the Security Type Matters

Your Wi-Fi security type determines how data is encrypted between your device and the router. Older protocols like WEP and WPA are broken and can be cracked in minutes with free tools. WPA2 has been the standard since 2004, but it has a known vulnerability called KRACK that allows attackers to decrypt traffic under certain conditions. WPA3, introduced in 2018, fixes most of those weaknesses and adds stronger encryption. Knowing your security type tells you whether your network is reasonably safe or whether you should upgrade your router or change settings.

How to Check on Windows

  1. Click the Wi-Fi icon in the system tray (bottom-right corner).
  2. Click Properties (Windows 10) or the (i) icon next to the connected network (Windows 11).
  3. Look for the Security type field. It will display something like WPA3-Personal, WPA2-Personal, or WEP.

If you’re on an older Windows version, go to Control Panel > Network and Sharing Center > your Wi-Fi connection > Wireless Properties > Security tab. The encryption type is shown there, though the exact label varies.

How to Check on macOS

  1. Hold the Option key and click the Wi-Fi icon in the menu bar.
  2. A drop-down will show network details, including Security (e.g., WPA2/WPA3 Personal).

Alternatively, open System Settings > Wi-Fi, click Details next to the connected network, and look for the Security field under Network Settings.

How to Check on Android and iOS

Android: Go to Settings > Network & Internet > Wi-Fi, tap the connected network, and look for Security or Encryption. On some phones (like newer Pixels), you may need to tap the gear icon or select “View more.� If the option isn’t visible, your manufacturer may hide it—you can always check via the router.

iOS: Go to Settings > Wi-Fi, tap the blue (i) icon next to the network, and look for Security. It will show WPA3, WPA2/WPA3, WPA2, or WEP. Older iOS versions may not show this, so you’d need to check the router.

How to Check in Your Router’s Settings

The most reliable method is to log into your router’s admin page. Open a browser, enter your router’s IP address (often 192.168.1.1 or 192.168.0.1), and sign in with the admin credentials. Then look for Wireless Settings or Security. The security mode is usually listed next to “Security Mode,� “Encryption,� or “WPA Mode.� If you don’t know your router’s IP, check the sticker on the router or run ipconfig (Windows) and look at the Default Gateway.

Common Problems and Misconceptions

  • “WPA2� is not the same as “WPA2-PSK.� WPA2-PSK (Pre-Shared Key) is the personal version for home networks; WPA2-Enterprise is for businesses with a RADIUS server. Most home routers use WPA2-PSK.
  • WPA and WPA2 are often shown as “WPA/WPA2� mixed mode. This allows older devices to connect but weakens security to the lowest common denominator. If possible, choose WPA2 or WPA3 only.
  • WEP is still on some old routers. It’s easily cracked—never use it if you can avoid it.
  • Some routers show “WPA2-AES� vs. “WPA2-TKIP.� AES is the stronger encryption; TKIP is outdated. If you have the option, choose AES.

How to Improve Your Wi-Fi Security

  1. Log into your router and set the security mode to WPA3 if all your devices support it (most phones and laptops from 2020 onward do).
  2. If WPA3 isn’t available, use WPA2-AES (or WPA2/WPA3 mixed mode if you have older devices).
  3. Set a strong passphrase—at least 12 characters, mixing letters, numbers, and symbols.
  4. Disable WPS (Wi-Fi Protected Setup) if you don’t use it; it can be a security hole.
  5. Update your router’s firmware regularly to patch security vulnerabilities.

Frequently Asked Questions

What does WPA3 offer over WPA2?

WPA3 uses stronger encryption (192-bit in enterprise mode, and a new handshake that protects against offline dictionary attacks). It also provides forward secrecy, meaning even if an attacker captures your traffic, they can’t decrypt it later even if they learn your password.

Is WPA2 still safe to use?

Yes, for most home users. The KRACK vulnerability was patched in 2017 via device updates. As long as your router and devices have up-to-date firmware, WPA2-AES is still considered reasonably safe. However, WPA3 is better if available.

Why does my phone show “WPA2/WPA3� as the security type?

That means the router is configured to allow both WPA2 and WPA3 devices to connect. It’s a transitional mode that’s safe, but it still allows WPA2 connections, which are slightly less secure than WPA3-only.

Can I check the security type from the command line?

On Windows, you can use netsh wlan show interfaces to see the authentication and cipher. On macOS, system_profiler SPAirPortDataType shows security info. On Linux, nmcli dev wifi list or iwconfig may show it. These are advanced but useful for scripting.

What if my router only supports WEP?

If your router is that old, it’s likely end-of-life and has other vulnerabilities. Replace it with a modern router that supports at least WPA2. In the meantime, avoid sending sensitive data over that network.
