FYI for anyone searching posts for info. Took a chance on an Intel AC 9260 in a PCIe x 1
Works great in both Windows 10 and Linux Mint 19.1 xfce.
Wireless and Bluetooth both worked great right out of the box on Linux,
Windows 10 it worked great after loading the drivers from the cd that came with the card.
The one I got from a Newegg marketplace seller is Fenvi FV-2030T from the link below
And actually, my wireless speeds are higher in the Linux operating system, than the Windows 10
For what it is worth.
