I just experienced this issue after rearranging PCIe adapters in my 0M5DCD board based box (Optiplex 390DT guts turned into Frankenputer.) I moved the wifi6 adapter up to the x16 slot, where a renesas USB 3.0 card was working fine. The EDUP branded Intel AX200 chipset based AX3000 Wifi 6 PCIe adapter did not show up after logging in. I copied dmesg to find a list of iwlwifi errors. I was able to reproduce this reliably. It occurred with multiple kernels of version 5.10.24. After moving the iwlwifi driven hardware back to a PCIe x1 slot, expected functionality resumed. bits of dmesg Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340 [ 24.094230] iwlwifi 0000:01:00.0: [ 24.094230] iwlwifi 0000:01:00.0: SecBoot CPU1 Status: 0x5ae1, CPU2 Status: 0x3 [ 24.097475] iwlwifi 0000:01:00.0: UMAC PC: 0x80480218 [ 24.100734] iwlwifi 0000:01:00.0: LMAC PC: 0x104 [ 24.103913] iwlwifi 0000:01:00.0: WRT: Collecting data: ini trigger 13 fired.
