In a condo in an urban population center, and next to a busy 700+ pupil elementary school across the street, WiFi (both 2.4 and 5 GHz) work beautifully. On 5GHz, seeing 600M down and 100M up, as per ISP contract, the same as on wired Ethernet.

I guess that's because people here tend to use 5G mobile networks and not so much WiFi, maybe not at all, so there's little contention. (Perhaps this makes it obvious, but not in the USA.)
