Automatic wifi detection and connection (like at airports)

Hi,
You know this situation - you get to an airport, mall, whatever, and there are lots of unsecured wifi APs. Now you want to connect to one that gives you free internet but you have to try each one manually then try to browse the internet until you succeed.

Is there any program that does this for you ?

Now, some wifi services give you a page in your browser asking you to login/register/pay. I want a program that tries to connect to, let's say google, and if that page loads, then the wifi is free and it remains connected.

This program would be useful to lots of you out there!

Ken.

Yeah. I have tried this tips once at the airport. It is works. But then my computer is running out of battery
