Most convention centers (and some airports) run a wireless network that is un-secured. No WEP or anything like that.
But when you try to browse to a web site, they have some router that intercepts your http traffic and you get diverted to some company that puts up a web page telling you that if you want internet access you have to pay something like $10 an hour, $50 per day, etc.
Is there any way to hack around that kind of setup?
Maybe they only monitor port-80? Maybe VPN will work?
Any ideas?
Is there a name for this kind of internet access?
