@Arvin17, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding wireless IRQ test! 

We're thrilled to have the opportunity to assist you and provide a solution.  

This failure can definitely be related to the Miracast issue you’re facing (connection starts but later drops). IRQ (Interrupt Request) problems usually mean the wireless adapter isn’t communicating smoothly with the system, often because of driver conflicts, outdated firmware, or resource conflicts in Windows.

Here are some steps you can try to fix this:

🔧 Troubleshooting Steps

Update / Reinstall Wireless Driver

Go to Device Manager → Network Adapters → Realtek RTL8852BE.

Right-click → Uninstall device (check "Delete the driver software for this device").

Restart your PC.

Download and install the latest Wi-Fi driver for your exact model from the HP Support site or directly from Realtek.

Update BIOS and Chipset Drivers

Visit your HP model’s support page.

Update the BIOS and Chipset drivers — these often fix IRQ conflicts.

Check Miracast Requirements

Ensure both your PC and TV are on the same Wi-Fi band (preferably 5GHz for stability).

If your router allows, lock the Wi-Fi channel instead of using “Auto.”

Power Management Settings

In Device Manager → Realtek Adapter → Properties → Power Management tab.

Uncheck: “Allow the computer to turn off this device to save power.”

Windows Updates

Run winver and check you’re on the latest Windows build.

Install all Optional Updates, especially under “Driver Updates.”  

Hope this helps! 

Take care, and have an amazing day!
