About faster WiFi in my house

This isn't exactly about the configuration of my computers but... I used to have Google WiFi (December 2017) with 3 access points in my house. It always seemed like a nice thing to have. And on a good day, I would get download speeds of 5-7MiB.

Whatever possessed me, maybe de-google-ification, but I got a TP-Link Deco X60 3-pack. And now I get 30MiB download speeds. At least that is the speed with 2 different computers both with Intel AX200 cards in them.

The new WiFi 6 standards do make a difference.
