Back before cellular data coverage as ubiquitous and cheap, getting on an using shoddy wifi was an essential skill for anyone with a laptop. The ability to lock onto a stable wifi router, piggyback on another network, or syphon some bandwidth from a network you shouldn't ... those with such abilities managed to book tickets or hotel rooms within seconds of a flight being cancelled. Or, if you were really evil, you kicked everyone in the terminal off the router, hogging all the bandwidth for yourself. At school I had a script to randomize my laptops MAC ever few minutes then reconnect to the school's network. Mine was the only laptop that never got throttled by the wifi police for using too much data in a given session.

I used to have a little wifi antenna on my car. Some called it "wardriving" but I called it being able to check my email while traveling.
