How to Fix Your Wi-Fi Network Isn’t Secure Message on Windows 11

Windows 11 is designed to help you stay safe while browsing the internet, especially when it comes to unsecured wireless networks. One of the warnings many users encounter is the “Your Wi-Fi network isn’t secure” message. This alert appears when you connect to a network using outdated or weak security protocols, such as WEP, TKIP, or Open (unencrypted) Wi-Fi. These protocols make it extremely easy for attackers to intercept your data — which is why Windows 11 flags them immediately.

If you’re reading this guide, your PC has likely shown this message, and you want to understand what it means and how to fix it quickly. The good news? This issue is almost always related to incorrect router settings, not your Windows PC — and you can resolve it in minutes.

In this in-depth troubleshooting guide, we’ll explain why you see the warning, what it means for your privacy, and how to fix it by updating your Wi-Fi security settings properly.

Let’s get started!

How to Fix Your Wi-Fi Network Isn’t Secure Warning on Windows 11

Below are the most effective solutions. Start with the router settings — that’s where the real fix lies.

1. Log In to Your Router’s Admin Panel

You’ll need access to your router settings to fix the security mode.

1. Press Windows + R.
2. Type:

cmd

3. Run Command Prompt.
4. Type the following command:

ipconfig

5. Look for Default Gateway — this is your router’s IP (usually):
   • 192.168.0.1
   • 192.168.1.1
   • 192.168.1.254
6. Open your browser.
7. Enter the IP into the URL bar.
8. Log in using your router admin username/password.

If you never changed them, look at the sticker on your router.

2. Change Your Wi-Fi Security Mode to WPA2-AES or WPA3

This is the main fix and the most important step.

Inside your router’s Wireless or WLAN settings:

1. Go to Wireless Settings → Security.
2. Look for Security Mode / Authentication Mode.
3. Select one of these:
   • WPA3-Personal (Best)
   • WPA2-Personal (AES) (Most compatible)
4. Avoid:
   • WEP
   • WPA-Personal
   • WPA/WPA2 mixed mode
   • TKIP encryption
5. Save the settings.
6. Restart your router.

Reconnect your device.
The warning should now disappear.

3. Change Encryption Type to AES Only

Some routers allow choosing between AES and TKIP.

Select:

AES (recommended)
TKIP (outdated – triggers the warning)

AES is secure, faster, and required for modern Wi-Fi speeds.

4. Disable WPS (Wi-Fi Protected Setup)

WPS has known vulnerabilities and sometimes forces weaker security modes.

1. Open your router’s admin panel.
2. Go to WPS Settings.
3. Turn off WPS.
4. Save and restart the router.

5. Update Your Router’s Firmware

Old firmware may not support current Wi-Fi encryption standards properly.

1. Go to Administration → Firmware Update (or similar).
2. Click Check for update or upload a firmware file.
3. Install the update.

After the update finishes, check Wi-Fi security mode again.

6. Forget the Network and Reconnect on Windows

After fixing router settings, reconnect cleanly.

1. Open Settings → Network & Internet → Wi-Fi.
2. Click Manage known networks.
3. Select your network.
4. Click Forget.
5. Reconnect and enter the password.

This forces Windows to re-read updated network security settings.

7. Reset Router to Factory Settings (Last Resort)

If your router won’t let you select WPA2/WPA3 or security settings are broken, reset it.

1. Find the Reset button on the router.
2. Hold it for 10–15 seconds.
3. Set up your Wi-Fi again using:
   • WPA2-AES or WPA3
   • A strong password

Windows will no longer show the insecure network warning.

8. Confirm Wi-Fi Security Standard in Windows 11

After fixing your router, verify that your PC is now using modern encryption.

1. Press Windows + I to open Settings.
2. Go to Network & Internet → Wi-Fi.
3. Click your connected network.
4. Look for Security type.

It should show: WPA2-Personal or WPA3-Personal

If you still see WEP, TKIP, or Open — the router settings were not applied correctly.

Wrapping Up

The “Your Wi-Fi network isn’t secure” warning in Windows 11 appears for a good reason — it’s protecting you from outdated and easily compromised wireless security protocols. Thankfully, fixing it is straightforward: update your router to WPA2-AES or WPA3, disable old encryption modes, and reconnect your PC.
