Hi @MLL88,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

Experiencing a blue screen of death (BSOD) with the error message "IRQL_NOT_LESS_OR_EQUAL" while using the Wi-Fi on your HP laptop at work can be frustrating. This error typically indicates an issue with a driver or hardware component that is trying to access a memory address it is not allowed to. Here are some steps you can take to troubleshoot and resolve the problem.

• Restart your laptop: Sometimes, the issue could be temporary, and a simple restart might resolve the problem. If the BSOD occurs only once, it might not be a significant concern.
• Update Windows: Ensure that your operating system is up-to-date with the latest Windows updates and patches. Microsoft often releases updates that address known issues and bugs.
• Update drivers: Outdated or corrupted drivers can often cause these types of errors. Check HP's official website for the latest driver updates for your specific laptop model, especially for the Wi-Fi network adapter. Download and install the latest drivers, following the instructions provided by HP.
• Check for Wi-Fi driver compatibility: If you recently updated the Wi-Fi driver and the issue started occurring after that, try rolling back to the previous version of the driver to see if that resolves the problem. Sometimes, new driver updates can introduce compatibility issues.
• Run Windows Memory Diagnostic: This tool can help identify memory-related issues. To access it, search for "Windows Memory Diagnostic" in the start menu and follow the instructions to run the test.
• Check for malware: Malware infections can cause system instability. Run a full system scan using a reliable antivirus software to check for any potential threats.
• Check for overheating: Overheating can cause various issues, including BSODs. Ensure that your laptop's vents and fans are clean and functioning properly. If necessary, use a cooling pad to help dissipate heat.
• Use Windows System Restore: If the issue started occurring after a recent software or driver installation, you can try using System Restore to revert your system to a previous state when it was working correctly.
• Check for hardware issues: If none of the above steps resolve the problem, there might be a hardware issue causing the BSOD. It could be related to the Wi-Fi card, RAM, or other components. 

Remember to back up your important data regularly, especially before attempting major system changes or updates.

I hope this helps. 
 

Take care and have a good day.
