The Case of the Vanishing Wi-Fi: Fixing Code 45 on Windows 11


I’m encountering a persistent issue with my laptop’s Intel AX200 160MHz Wi-Fi adapter, which is displaying Code 45. Although I typically use an Ethernet connection, I recently needed to rely on Wi-Fi during a trip. Unfortunately, the Wi-Fi option seems to vanish from my settings about 70% of the time when I start up the computer. I’ve attempted several temporary fixes, such as updating the drivers from Intel’s official website and resetting the network settings, but the problem persists.

I also use OpenVPN for remote access to my office server, and I’m unsure if this could be influencing the Wi-Fi adapter’s functionality. My laptop, a dc-1045np model, is updated with the latest stable release of Windows 11.

Could this issue be related to my VPN usage, or is there another underlying problem that I’m overlooking? Any guidance on resolving this would be greatly appreciated.

Thank you.”


Encountering a Code 45 error with your Intel AX200 160MHz Wi-Fi adapter can be quite frustrating, especially when the Wi-Fi option intermittently disappears from your computer settings. This error signifies that the device is not recognized by your system, which can be caused by various factors. Let’s delve into some troubleshooting steps and considerations that might help resolve this issue.


Hardware Check

  • Ensure the Wi-Fi adapter is securely connected if it’s an external device.
  • For internal adapters, check your laptop’s manual or manufacturer’s website for any specific instructions regarding hardware issues.
  • 2.

Driver Management

  • Continue to check for the latest driver updates from Intel and Windows Update.
  • If the problem started after an update, try rolling back to a previous driver version.
  • 3.

Network Reset

  • – Perform a network reset by going to *Settings > Network & Internet > Status* and selecting *Network reset*.
  • 4.

    Power Management Settings

    • In the Device Manager, adjust the power management settings of the Wi-Fi adapter to prevent the system from turning it off to save power.
    • 5.

    VPN Configuration

    • Investigate whether OpenVPN is configured to alter or disable network adapters when not connected.
    • Temporarily disable OpenVPN to determine if it’s causing the issue.
    • 6.

    System Scans

    • Use Windows’ built-in troubleshooters to diagnose and fix network problems.
    • Run System File Checker (SFC) and Deployment Image Servicing and Management (DISM) scans to repair system files.


  • VPN Interference

    : VPN software can sometimes interfere with network adapter settings. It’s possible that OpenVPN might be affecting the Wi-Fi adapter’s functionality, especially if it’s configured to modify network settings.

  • Underlying System Issues

    : There could be underlying issues with Windows 11 that are causing the Wi-Fi adapter to malfunction. This could range from system updates to conflicts with other software.

  • Hardware Malfunction

    : In some cases, the Wi-Fi adapter itself might be failing. If it’s an external device, try it on another computer to see if the issue persists.

  • Conclusion:

    The Code 45 error is a challenging problem that requires a methodical approach to diagnose and resolve. By exploring both software and hardware angles, you can narrow down the cause of the issue. If the problem continues after trying these steps, it may be time to consult with a professional technician or reach out to the laptop’s manufacturer for further assistance. Remember, persistent issues like these can sometimes be indicative of a deeper problem that may require expert intervention.
