My Pavillion laptop does not see any wireless connections.  I've tried all the troubleshooting options but cannot get it to work.  Any thoughts on how to fix this?

Thank you for your response.  To answer your questions:

My laptop is an HP Pavillion Notebook;

System ID: 820B;

Product ID: H7Q97UA#ABA

I purchased it about 3 years ago.

It came with Windows 10, 64 bit

Wifi card is correctly installed

Additional info:  I ran HP's System Tests and the laptop failed the Wireless IRQ test.

Sorry - I just noticed that it also failed the Wireless ROM test.

can you check the reference, it seems not to match a model

But if the card is out of order, your best bet will be to buy a usb wifi dongle!

Thanks for your patience.  When I click on the link you sent I am taken to a site that deals with domain names.

Additional info:  I tried an external network adapter and the laptop didn't recognize it.  The same error message appeared.
