I'm at the hospital and I turned my Wifi ON. The browser can't get to the IP address 22.214.171.124 for the "accept" page to allow the device on the network. But my laptop seems fine (I'm writting this e-mail). But also, when Wifi is on but you can't reach the outside network, you can't actually do anything... If the Wifi can't reach google.com or something, use 3G so I don't miss all my e-mails with a incorrectly configured wifi.
