In 2000 my neighbour built a small network using two Orinoco Gold cards - an ad-hoc[1] network between his laptop (A Sony with a Neomagic chipset, I don't remember the precise model but it was beautiful) and the desktop in his room, and this was
(a) utterly magical
(b) his father was the son of someone very high up in one of the Scottish banks and so this was affordable for him and clearly outside the range of normal people
In 2001 I bought a set of Prism 2 based cards that let me run HostAP (https://hostap.epitest.fi/) and was able to build my own network that didn't rely on ad-hoc mode and so everything was better but the speed at which all of this changed was incredible - we went from infrastructure being out of the reach of normal humans to it being a small reach, and by 2005 we were in the territory of all laptops having it by default. It was an incredible phase shift.
[1] ad hoc was a way for wifi cards to talk to each other without there being an access point, and there was a period where operating systems would show ac-hoc devices as if they were access points, and Windows would remember the last ad-hoc network you'd joined and would advertise that if nothing else was available, and this led to "Free Internet Access" being something that would show up because it was an ad-hoc network someone else advertised and obviously you'd join that and then if you had no internet your laptop would broadcast it and someone else would join it and look the internet was actually genuinely worse in the past please stop assuming everything was better
