Fix WiFi Password Incorrect Error on Windows 11 and 10

[ChatGPT]

In the world of technology, WiFi connection problems can be both frustrating and perplexing. If you're using Windows 11 or 10 and find yourself facing the notorious "WiFi password incorrect" error—despite being sure that the entered password is indeed correct—don't worry. This article covers the common causes behind this issue and offers several effective solutions.

Understanding the Problem​

When a computer fails to connect to WiFi, citing an incorrect password even after entering it correctly, it could stem from various reasons. Common scenarios include recent changes to your network settings, the introduction of new hardware, or misconfigurations. Before diving into specific solutions, it is essential to undertake a few basic checks:

1. Verify the Password: Always double-check that you are entering the correct password. Typographical errors are common because passwords are case-sensitive and may contain special characters.
2. Check Hardware: Ensure the physical WiFi router is turned on. Sometimes, routers may unintentionally power down.
3. Keyboard Issues: Ensure the keyboard is functioning correctly. If certain keys are not working, it can lead to incorrect entries.
4. Language Settings: Ensure that the language or keyboard layout settings on your computer match those used to create the password.

   Why the "Incorrect Password" Issue Occurs​

   If you've verified everything but still encounter issues, the underlying causes can include:
   • Network Adapter Problems: The network adapter may need troubleshooting.
   • MAC Address Filtering: Your router may have specific security settings that require your device's MAC address to access the network.
   • WLAN AutoConfig Issues: If this essential service isn’t functioning correctly, a wireless connection may not be established.
   • Third-Party Applications: Certain MAC address changing applications may interfere with your connection.

     Step-by-Step Solutions​

     Here are some detailed solutions you can follow to resolve the "WiFi password incorrect" error:

     1. Change the Default WiFi and Router Password​

     It's critical for security reasons that the default passwords provided by router manufacturers are changed right away. This helps prevent unauthorized access to your network. Here’s how to change your WiFi password:
   • Log into your router's configuration page (usually by typing 192.168.1.1 or 192.168.0.1 into your browser).
   • Locate the WiFi settings section.
   • Change the WiFi password and save the changes.

     2. Run the Network Troubleshooter​

     Windows 11 includes a built-in troubleshooter to help identify and resolve network issues:
   • Open the Start Menu and type 'Get Help' to search for the application.
   • Select Check your network connection status from the suggestions.
   • Click on Launch the network troubleshooter and follow the prompts.

     3. Reset the Network​

     If the problem persists, you may need to reset your network settings completely:
   • Press Win + I to open Settings.
   • Navigate to Network & internet > Advanced network settings.
   • Click on Network reset, then proceed with the reset by confirming the operation. This will disconnect and reinstall your network adapters.

     4. Remove MAC Address Filtering​

     If your router features MAC address filtering, it could block devices that are not explicitly allowed. To check and remove restrictions:
   • Access your router's configuration as described earlier.
   • Locate the MAC Address Filtering setting.
   • Ensure your device’s MAC address is added or disable MAC filtering entirely for troubleshooting.

     5. Restart the WLAN AutoConfig Service​

     Restarting this service may re-establish proper connectivity:
   • Open the Task Manager by right-clicking the taskbar and selecting Task Manager.
   • Go to the Services tab and look for WLAN AutoConfig.
   • Right-click on it and select Restart.

     6. Disable MAC Address Changer Software​

     If you've installed any third-party applications that change your MAC address, consider temporarily disabling them:
   • Disable the application or uninstall it to see if connectivity issues resolve afterward.

     Additional Considerations​

     Common Questions and Answers​

   • Why can't I connect to WiFi even if the password is correct?
   If you cannot connect despite having the right password, it could be due to security settings in the router, such as MAC filtering or incorrect router configurations.
   • Why won't my computer accept the WiFi password?
   This may happen if the router is switched off, or if there's an issue with your network settings that requires resetting.

   Conclusion​

   Experiencing issues with WiFi connectivity can be a common but bothersome problem for users. While the frustration may stem from simple password errors, it can also be related to deeper network configuration issues. The solutions provided above should help you troubleshoot and resolve the "WiFi password incorrect" error on your Windows 11 or 10 device. Should difficulties persist, consider reaching out to your Internet Service Provider (ISP) as a final measure for assistance. By ensuring the right settings and operating conditions, you can enhance your connectivity experience with Windows 11. Source: The Windows Club WiFi password incorrect but is correct in Windows 11
