trs96,
Here is what it looks/looked like:

Broadcom BCM94352HMB Dell DW1550 802.11ac WiFi Card Bluetooth 4.0 867Mbps
It came with the
Broadcom BCM43228 802.11a/b/g/n (Dell DW1530) Mini PCIe card, but I have replaced that with
Broadcom BCM94352HMB 802.11ac WiFi Card Bluetooth 4.0 867Mbps (Dell DW1550) MiniPCIe card. It plugs right into the PCI card shown.
As a test last night - I powered OFF, disconnected the SSD where my High Sierra is installed and working - and put in the old SSD where Windows 7 was installed. I formatted it, and installed Windows 10 (64-bit). It immediately recognized the WiFi and installed drivers. When it was done with the install - I had WiFi with no issues, as it wanted to connect to my home network. But searching in Windows 10 for BlueTooth - it was saying that there was no BT Controller present.
So.... HMMMMMmmmmm
I thought, either a bad PCIe card, or that USB header must be connected.
I will have to dig for a cable to do this (I am sure I have one here). I have boxes and boxes of old cables.
