I'm new to iPhone having recently come from Android. I'm at work where there are several wifi networks. The passwords change periodically. At the moment, whenever I wake my phone, I get six dialogue boxes pop-up one after the other that say "Wifi password incorrect." How can I turn these off? Or somehow tell the phone I don't care? The pop-up boxes are very annoying and I don't understand why the iPhone thinks this requires my immediate attention every time I open my phone.
