"Rig Your Laptop For Wi-Fi Do-it-yourself Wi-Fi is easy and cheap. To piggyback on your neighbor's hot spot for free, buy a Wi-Fi PC card and stick it into your laptop. Then get ready to pick up free wireless networks in your area. If you can't get a wireless signal at home, then buy an off-the-shelf access point to install. Be aware: most free public hot spots aren't secure. "
Well, it seems that every Wi-Fi user is trying to steal bandwidth. Bad boys! Also "public hot spots aren't secure" make it seems like using hot spots are bad things. I think the reporter wanted to say that most Wi-Fi installations are not secure, allowing people to connect to it without requiring authorisation.
