HP Wireless Button Driver is installed?

AND your F2 diagnostic shows what?

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

HOW DO I USE DIAGNOSTICS?

Hello sir, thanks for your reply...when I tried to run test, this was the reply...what should I do...

Hi, @Archy_Raja 

If the wifi adapter is not showing up at all in the device manager, most likely it has died on you and needs to be replaced.

You can first try removing and firmly reseating the wifi card and see if that gets it to show up again.

See if you can leave the antenna cable connected when you do that to facilitate easy reinstallation.

Sometimes the contacts get oxidized and it loses the electrical connection.

Below is the link to the service manual for your notebook.

The wifi card R & R procedure can be found in chapter 6.

Here is the system information sir...

Looking at the screenshot, what that means is the device is either hidden or once used to be there.

See if uninstalling the hidden Realtek wifi device and restarting the PC gets it to show up again.

Also click the uninstall driver box.

If it does not reappear as unhidden, you can pretty much bet it is a hardware problem.

Hi

Just to supplement Paul's superb answer...  Show Hidden Devices may have it included.
