This happens if I'm tethering my phone, at school, at home, etc. It can't be an internet connection. Like I said it seems like when I click on the airport icon it stops scanning and then the page seems to load up, otherwise the page will continue to load and then finally start to show me the website.
I'll try that thing you posted out and see if that works out for me. I'm thinking about going to my default Wifi card because my Mini is starting to get really really hot. It's like dipping your finger in dunkin donuts coffee and that's not an exaggeration.
