Using the free wifi at a café

[Molly]

I have a question about getting my XO to use the free wifi at a local cafe. They have an open access point which directs your web browser to a page where you must log in. My XO s-l-o-w-l-y tried every network in range, finally did connect to the cafe's wireless router, and then nothing. Neither Browse nor Opera would find that log in page--they gave Page Not Found errors. I tried for about 15 minutes and then gave up.
