You want to re-use your m.2 wlan card. There are adapters to hold that card and plug into PCIe x1 slots.

The problem I have here is that for that 20 some bucks I can get some USB or PCIe WiFi stick or card.
I replaced a defective mobo, which supported an M.2 WLA Ncard (socket 1, key A) with a new mobo that has 2 Ultra M.2 sockets (One supports PCIe Gen3 x4 & SATA3, the other one supports PCIe Gen3 x4 only). Any idea if its possible to connect with an adapter of some sort, and if so, where can I get one? I see lots of references to adapters in the forum, but they all seem to be SATA, not WLAN, so I'm not sure if they are relevant to my position
Thanks
Jim
