Tried that too, was sitting outside a well known hotspot in Orlando and waited for half an hour but no connection could be made (was a strong signal also...)

Was only able to connect at the hotel where you where redirected to a website and you had to fill in a code provided by the hotel....

Since my Italian hotel has a WIFI hot spot I fear it is not gonna work again....

will try over here in the Netherlands with a Mc Donalds and see if it will connect there.....
