Many embedded systems or supercomputers disable modules for security or simplicity, but then all needed drivers must be built in. WiFi is a common casualty because it’s normally modular due to firmware blobs provided as-is from WiFi manufacturers.

Also, many supercomputing facilities and hardened servers prohibits direct networking with WiFi drivers (because, unverifiable firmware blobs).

Your homelab should provide the direct Ethernet connect to your desktop.
