After several days of succcessully connecting my Ipad2 to the hotel's wifi, it stopped working today after I had begun allowing various updates to apps. Previously, after I selected the hotel's wifi network, a screen popped up where I typed in my code to allow me wifi access. Now a screen pops up, but it is Apple, advertising the iPhone 5. No matter how many times I try, I get this same screen. When I open Safari, I also get a messsage that I am not connected and the Apple IPhone 5 page appears. Any ideas?

The biggest problem I've had with hotel wifi is when they change the password for connection when I think I'm connected.

Another thing to try is to close everything (do the 4 finger swipe up, hold an app until it jiggles, then tap the minuses to close each app.) Then hold the home and sleep buttons until the apple appears. Now reconnect to hotel wifi.
