Hi, @cggarland
I saw your pictures on that other discussion.
You have a different model wifi and bluetooth adapter (Ralink) than the Atheros one.
W10 Wifi Driver...

Then see if this W10 Bluetooth driver works...
This package contains the driver installation package for the Mediatek Bluetooth in the supported notebook models running a supported operating system.

You will have to purchase a USB wifi adapter, or replace the Ralink wifi card with this model...
Intel Centrino Advanced-N 6235 HP Part # 670292-001.
You should be able to find this model wifi card on eBay.
Search by the HP part number, not the model of the wifi card.
Below is the link to the service manual, where you can find the wifi card removal and replacement procedure.
