What I learned at uni is that because all wireless transmitters and receivers share the same "air" it's always only as good as a single cable basically. Means that having 100 senders and receivers wirelessly they need to share the airspace and thus share bandwidth. If you had 100 wires, they could all send and receive without interfering.

Wires almost always seem to show better performance and consistent reliability than wireless connections (irrespective of the rated specs).

I have a WiFi 6/AX router and clients and irrespective of the type of data being sent (lots of small files, large movie files), my desktop Gigabit Ethernet connection is always faster and more consistent.

This is with ~5m line of sight of the router. It gets even more funky when the connection has to pass through 2 thick walls.
