I'm having the same problem at all three of my favourite hotspot locales in Philadelphia. I'm connecting to the hotspot but can't get an IP address. Could this be an ISP issue? Have they found some way of clamping down on "unauthorized" sharing of lines? My only theory is that some security update on Windows is preventing the connection.
I'm having problems about 1/2 the time connecting at public spots using a dell notebook xp pro with an internal intel 2200 bg card. At home, I can connect without problem. At the hotspot, I often see an excellent signal strength but am not able to connectwith or without the firewall running. Any thoughts on trouble shooting?
