Hi macrumors, I have an iPad 4 WiFi only. At school we have WiFi everywhere. All we have to do is to click on the SSID and a web authentication page pops up and you have to enter your creditentials to use the internet. Just recently I have started to get this message "hot post login cannot open the page because the network connect was lost." Well this is odd as I am usually 1.5m away from the router. My iPod touch 4G can connect without a problem and my friends iPad mini can too. What's the problem? I have restored, clicked on reset network settings but still I get the message. I didn't get this message when I had my iPad 3 on 5.1.1 a long time ago. But now that I got the iPad 4 a few weeks ago, it starts showing this message today.
