Question Onboard WiFi Not Working...New MSI B450 Gaming Pro Carbon AC

BIOS Version - E7B85AMS.180

Onboard WiFi isn't working. I just put together a PC for my nephew, basically using the same parts as I used for my personal build six months ago.

On my build, after downloading Live Update 6 and installing the included drivers the WiFi became available and showed 'WiFi' on the Left Menu under 'Network and Sharing.'

Last night I made sure Intel BT and WiFi drivers were selected, downloaded and it then showed 'installed,' but even after trying and restarting several times WiFi isn't showing on the left side 'Network and Sharing' menu.

Usually, tapping the 'globe' icon in the taskbar shows the ethernet connection and show's the ability to turn WiFi (and Airplane Mode) on/off, but only 'no Ethernet connection' is showing.

I checked in BIOS and made sure WiFi was enabled, which it is. I looked at Device Manager->Network Adapters and did see the ethernet adapter (I believe it was Realtek), as well as about 7 'WAN xxxxxx' (I'm thinking these are from the Netgear AC1200 USB Network Adapter I'm temporarily using for internet connection) ,but nothing saying 'WiFi.'

Any help would be greatly appreciated!

Back Panel shows two WiFi/Bluetooth Antenna connectors.

Looking at what comes in the box, it appears you need to buy an antenna.

Both antennas are (have been) connected.

I downloaded (initially and now again) the Intel WiFi Drivers from MSI.com (Win 10 64), extracted then ran the application (which it now gave the option to 'Repair' or 'Cancel')... but it doesn't show up in Device Manager. Also, all Windows Updates are installed.

Device Manager only shows the Intel Ethernet adapter and multiple 'WAN Miniport XXXXX.'

I wanted to Delete it then reinstall, but I don't even have the option and I'm unsure where else to look for possible solutions.

Can I delete everything in 'Network Adapters' and Microsoft will reinstall the WAN Miniport' Drivers?

Any other suggestions?
