I’m new to wireless and have no idea how to find a hotspot before I get somewhere and use site survey. What airports offer free public WiFi? The airports I’m specifically curious about are Logan, O’Hare, SeaTac, and Denver. A search through Google led to the seedy underworld of unnavigable websites and shady ISPs. I’d like to kill time getting some work done, but if I have to pay $7 at each airport, I’d rather spend it at the bar than updating this blog.
