I had an Orinico Gold WiFi card in my PCMCIA expansion pack for a Compaq Ipaq PDA back in the early 2000s. It was awesome!
This was back before ubiquitous open WiFi and encryption.
The heyday of wardriving (IMHO) was before the industry got its shit together with WPA.
Because before WPA, there was WEP. Which it turns out had multiple vulnerabilities, given enough traffic.

Ergo, there was a period from ~1999-2004 whereby one could aim a Pringles cantenna at a neighbor's AP and crack their WEP password in order-of-an-evening (depending on how much traffic they were generating).
Not that I ever did such a thing, mind you.
