Hi, Becareful for online banking and other secure transactions while browsing from that wirless connection. As you got it free it doesn't have any authentication mechanism and that probably, the guys who set up also not took any measured for security settings such as data encryption. Just my guess that the guy might be dumb or smart ace, who want to trap any surfer via his free wireless service. Security is very cirtical on wirless medium. So, it can be track any packet(data) which travel through wirless connection at normal situation on that free service by it provider. But there are also, many security measured which can safe guard from such action. As there is no guarentee So, becareful...............
