Hi:
Your PC is not supported by HP for W10, W8.1, W8 or W7.
I haven't read any reports of the Broadcom wifi adapter disappearing after the upgrade to W10.
Was the wifi adapter turned on during the upgrade?
If you post the full model number or product number of your notebook, I will give you the links to the Vista drivers you need for the coprocessor and base system devices,
Vista was the newest OS for which HP provided drivers.
What is showing up as a nvidia nforce networking controller, is the ethernet (wired) adapter.
After you provide the requested info, and while you are waiting for my reply with the drivers, see if you can get the wifi adapter to show up by doing this...
Make a bootable Ubuntu installer.
Download Ubuntu from the link below.
https://ubuntu.com/download/desktop
Here is a tutorial for how to make the bootable installer.
https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview
Boot from the installer and select the option to 'Try Ubuntu without installing.'
See if you can turn on the wifi adapter in Ubuntu.
If you can, shut down the PC, remove the installer and when you are back into Windows, the wifi should be working.
Also note that the dv9000 model series was plagued with overheating issues and those damaged the motherboard.
One of the most common problems was the wifi adapter completely disappears from the device manager due to the power to the slot it is plugged into is lost due to that part of the motherboard failing.
If you can't get the wifi to work, the only option would be to purchase a USB wifi adapter.
They make some pretty small ones that hardly stick out of the USB port and even come with Bluetooth...
