> I've also tested 160 MHz channels, which quickly run into the ~930 Mbps TCP throughput limit of a gigabit Ethernet connection, but perform worse at range. I'll cover 160 MHz channels and 2.5 Gbps Ethernet in more depth when the U6-Enterprise leaves early access

So yeah, when the author limits the tests to <1Gb none of the results were >1Gb. Who would have expected those results.

I've had >1G WiFi 5 networks in operation since 2018. It didn't require 6Ghz.

Your equipment or your environment may not have enabled it, but it was around.
