I have an Ipad2 32 gb and it is connects to the wi-fi at home and at work. When I am using the wifi at my workplace, I can download my email using the email app on the Ipad, but I cannot open a webpage nor connect to the app store. Safari just says "Safari cannot open the page because it could not connect to the server". I already tried resetting my network settings.
I have the exact same issue - everything (safari, email, other apps that use internet) works well at home.
At work, safari and facetime DO NOT. Skype, email, eBay app, do. On the same work wifi, my Android based phone connects and web works fine. Reset of network settings did not help.
