Windows can't connect to this network after password change and how to fix it

After changing your Wi-Fi password, Windows may fail to connect even when you enter the new password correctly because it still uses the old saved password. To fix this, you need to remove the old Wi-Fi network profile and reconnect with the updated password. If that doesn’t work, resetting your network adapter or running Windows’ network troubleshooter can help clear any lingering issues.

Why does Windows refuse to connect after I changed my Wi-Fi password?

Windows stores your Wi-Fi passwords and settings as network profiles. When you change your Wi-Fi password, Windows might still try to use the old one saved in its profile. Even if you enter the new password, the mismatch with the saved profile can cause errors like "Windows can't connect to this network." This happens because Windows relies on outdated information until you update or remove the saved profile.

Could saved network profiles or cached credentials be causing this problem?

Yes. Windows keeps a profile for each Wi-Fi network you connect to, including your password and other settings. These profiles let Windows connect automatically without asking for a password again. After a password change, the saved profile conflicts with the new password. Removing or resetting the saved profile forces Windows to forget the old password and request the new one. This usually fixes connection problems caused by password changes.

How do I forget the old Wi-Fi network and enter the new password properly?

To update your Wi-Fi password on Windows, remove the old saved network profile first:

1. Click the Wi-Fi icon on the taskbar to open the network list.
2. Find your Wi-Fi network name (SSID).
3. Right-click (or press and hold) the network and select "Forget". This deletes the saved password and settings.
4. Click the network name again to reconnect.
5. Enter the new Wi-Fi password when prompted.
6. Click "Connect".

If you don’t see the "Forget" option in the network list, you can also:

Start Menu > Settings > Network & Internet > Wi-Fi > Manage known networks
Select your network > Forget

When should I reset my network adapter or troubleshoot other Windows network issues?

If forgetting and reconnecting to the Wi-Fi network doesn’t fix the problem, your network adapter or settings might be stuck or misconfigured. Resetting the network adapter refreshes these settings and can solve connection issues.

Reset your network adapter if:

• Windows still can’t connect after forgetting the network and entering the new password.
• You see errors like "Network adapter not found" or "Limited connectivity."

To reset the network adapter:

1. Open the Start menu and type "cmd".
2. Right-click Command Prompt and select "Run as administrator."
3. Enter these commands, pressing Enter after each:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

4. Restart your PC.

Alternatively, use Windows’ built-in troubleshooter:

Start Menu > Settings > Network & Internet > Status > Network troubleshooter

Follow the instructions to diagnose and fix network issues. These steps refresh your network settings and help Windows connect using the new password.

How can I confirm that my Windows PC is connected and online after fixing the issue?

To check if your PC is connected:

• Look at the Wi-Fi icon on the taskbar; it should show a connected status with signal bars.
• Open a web browser and visit a website you don’t visit often to avoid cached pages.
• Open Command Prompt and run:

ping www.google.com

If you see replies with response times, your internet is working.

• In Settings under Network & Internet, your Wi-Fi network should show as connected with internet access.

If these checks fail, try reconnecting or resetting your network adapter again.

What can I do to avoid this problem when changing my Wi-Fi password in the future?

To prevent connection issues after changing your Wi-Fi password:

• Disconnect your Windows PC from the Wi-Fi network before changing the password.
• Update the saved password on all your devices immediately after changing it.
• Restart your router and your Windows PC after the password change to refresh network settings.
• Consider setting up a guest network with a separate password for other devices. This way, you can change your main password without affecting all devices at once.

These steps help Windows and your devices switch smoothly to the new password and reduce connection errors.

Conclusion

Start by forgetting your old Wi-Fi network on Windows and reconnecting with the new password. If that doesn’t fix the issue, reset your network adapter or run Windows’ Network Troubleshooter to clear stuck settings. After applying these fixes, confirm your connection by checking the Wi-Fi icon and testing internet access. Taking simple precautions when changing your password, like disconnecting beforehand and restarting devices, can prevent this problem in the future.
