And with ISPs supplying higher and higher speeds, WiFi is showing it's limits. On 2.4GHz you used to see 54Mbps tops. And you see this often today if the WiFi client is well, not well matched with the router.

Besides the fact that WiFi is half duplex and shared air space where your Ethernet goes full duplex and does not have to share the air space.

I wish there was a nice article to go over all this but the short story is that we expect WiFi to be slower than wired. Move to 5GHz and keep the distances to about 20 feet for top performance.

Any client that wants wired speed over WiFi will be your most difficult client until they learn how things work.
