"Free Public WiFi" was never free, and never public, and not actually a Wi-Fi service. It likely started as a joke or prank, but then spread around the world because of a quirk in pre-SP 3 versions of Windows XP:
When a computer running an older version of XP can't find any of its "favorite" wireless networks, it will automatically create an ad hoc network with the same name as the last one it connected to -– in this case, "Free Public WiFi." Other computers within range of that new ad hoc network can see it, luring other users to connect. And who can resist the word "free?" |
