Over and over again, I’ve seen people fix some wireless-related problem and go “wow, I had no idea how much better this could be!” • Wireless protocols often silently operate in an extremely degraded state that makes them substantially worse than wired equivalents.

I live in an apartment building that is located within the city core of my city. When I scan for WiFi networks I can see at least 25 from my main workstation. On my laptop, standing in the middle of the front courtyard, you can see at least 40 networks. Mind you, this is only WiFi networks; I’m not including everything else that might be using the 2.4 GHz spectrum, like Bluetooth or other kinds of wireless devices.
I switched to wired devices a long, long time ago precisely of unreliable connections, network lag, and the fact that WiFi optimization is more of an art than any sort of science, and that’s before you bring in newer WiFi versions. I just recently rewired my apartment to have Ethernet all over and be able to throw around 4K media with abandon.
