antenna connection

[Doug-1961]

I was changing the power supply and noticed two loose wires.  I thought they were originally connected to the motherboard.  After doing a little research, I believe these wires are the wireless antenna.  They run to the top of the unit and disappear behind the inner cover of the unit.  I am wondering if and where they get attached to the motherboard....or do they not get connected at all.

Hi:

The product specs page for your PC indicates that it comes with dual band wifi with bluetooth.

So the loose ends of those antennas have to be reconnected to the wifi card.

Here is a picture of the motherboard your PC has.

I don't see anyplace where the wifi card plugs directly into the motherboard, unless it is located in that relatively empty space on the very lower right bottom of the picture, below the dark blue SATA port and to the left of the white SATA port.

Is it in an adapter that is plugged into the one short, black PCIe x1 slot pictured on the lower left?

Anyway, somewhere in there, your PC has a M.2 wifi card, that looks like the picture I posted below the motherboard picture.  The two antennas connect to the gold colored terminals on the wifi card.
