It's no secret that blue screens are common system errors and can be caused by a variety of factors, from hardware failures to software conflicts.

Lately users reported seeing a BSOD error after installing or updating their Wi-Fi network card. The error is usually accompanied by: Your device ran into a problem and needs to restart. We are just collecting error information and then we will reboot.

Stop code: DRIVER_IRQL_LESS_OR_NOT_EQUAL

Additionally, the files that failed could include Netwtw00.sys, NETwlv64.sys, Netwtw08.sys, Netwtw04.sys, Netwtw06.sys, Netwtw10.sys, etc.

These same files are associated with Intel Wi-Fi adapters. But fear no more, here we explain how to solve it:

How to Fix Blue Screen after installing Wi-Fi card

1. Driver Rollback (Initial Troubleshooting):

Leveraging System Restore Points: If a system restore point was created prior to the Wi-Fi card installation, consider utilizing System Restore to revert your system state to a known functional point. This can potentially eliminate configuration changes or driver conflicts that might have triggered the BSOD.

Driver Rollback within Device Manager: For a more targeted approach, you can attempt to roll back the Wi-Fi driver to a previous stable version. Access Device Manager through the WinX menu (right-click on the Start menu icon) and locate your Wi-Fi adapter under "Network adapters." Right-click on the adapter, select "Properties," and navigate to the "Driver" tab. Click "Roll Back Driver" to revert to a prior version that may not have caused compatibility issues.

System Reboot: Following either a system restore or driver rollback, restart your computer to allow the changes to take effect. Observe if the BSOD issue has been resolved.

2. Driver Compatibility and Updates:

Manufacturer Identification: Assigning proper driver compatibility is crucial. Identify the exact make and model of your installed Wi-Fi card by consulting your system documentation or Device Manager.

Manufacturer-Sourced Drivers: Visit the official website of your Wi-Fi card manufacturer and locate the latest driver package specifically designed for your card model and your Windows 11 version. Download the appropriate driver package, ensuring it includes both Wi-Fi and Bluetooth drivers if applicable.

Driver Installation and Reboot: Double-click the downloaded installer to initiate the driver installation process. Consider uninstalling existing Wi-Fi drivers beforehand to prevent conflicts. Restart your computer after installation to finalize the driver update.

3. Advanced Troubleshooting (if Necessary):

Reinstalling Windows with Driver Integration (Last Resort): Reinstalling Windows 11 should be considered a last resort due to the potential for data loss and the time involved. Ensure a comprehensive backup of all critical data exists before proceeding. If feasible, download the Wi-Fi drivers beforehand and integrate them into the Windows 11 installation media using a tool like "Rufus" (consult online resources for specific instructions). This streamlines driver installation during the Windows setup process. Proceed with reinstalling Windows 11 using the official Microsoft media creation tool or your system's recovery options. Once Windows is reinstalled, install the Wi-Fi drivers (obtained beforehand or through Windows Update) to establish network connectivity.

Important Considerations:

Trusted Driver Sources: Always download drivers directly from the manufacturer's website to avoid potential security risks associated with untrusted sources.

System Stability: Modifying system settings like driver configurations can impact system stability. Exercise caution and create a system restore point before making significant changes.

With these steps, you should be able to effectively address the BSOD issue and restore stable Wi-Fi functionality on your Windows 11 system. If challenges persist, consider hiring a qualified IT professional for further advanced diagnostics.
