There are two parallel types of cards - the PCIe versions and the CNVio versions. They look identical, but are not compatible with each other. You will need to use the correct type for your motherboard. Here's a comparison of comparable cards:

802.11 ac 1.73gbps max:

- AC-9560 - CNVio

- AC-9260 - PCIE

"WiFi 6" 2.4gbps max:

- AX-201 CNVio

- AX-200 PCIe

Here's a comparison link at intel showing the above four cards.
