Hi Everyone,
I’m trying to understand why an M.2 A/E-key to M-key adapter works on one system but not another, even though both have M.2 slots that appear compatible.
To clarify, I am not using NVMe storage on the adapter but installing a NIC instead. The end goal is to have four Intel AX210 NICs installed on one PC using the NVMe slots. I am using an M.2 A/E-key to M-key adapter inside an NVMe slot so I can mount an Intel AX210 WiFi card on it. There are four LED indicators labeled D2, R6, R7, and D1.
On a CWWK X86-P5 system, this works perfectly: the AX210 is detected and functions normally through the adapter. The D1 LED is also on and bright blue.
However, on a Minisforum MS-A2 (Ryzen 9 7945), the same adapter and AX210 card do not work. The adapter LEDs for D1 and D2 are dim but on, but the device is not detected by the OS.
My question is: why would this kind of A/E-key adapter with a WiFi card work on the CWWK system but not on the Minisforum? Is this due to BIOS restrictions, PCIe lane configuration, or differences in how the M.2 NVMe slot is implemented between these boards?

- Both support PCIe 3.0
