I bought these antennas to connect with my wifi card, an Intel Killer AX1690i.

Here you can see a picture of the antenna connector and the Wi-Fi card. I paid special attention in making sure the description on the antenna stated it was compatible with Intel M.2 cards.

I am having a surprisingly tough time connecting them, currently to no avail, so I would like to know if I am doing anything wrong, if I was sent the right product, if you have any tips etc.
