iPhone WiFi does not work even after backup
My WiFi does not work (network router = FritzBox) any more with my iPhone, even though I have tried all of the following:
- reset network setting of iPhone
- restart of iPhone
- backup and new installation of iPhone.
The router works with another iPhone (iPhone 4), but not with mine any more. A few days ago, it also worked with my iPhone. But now it does not connect automatically with the WiFi. If I connect it manually, it says network connection failed (tried several times, password used was correct, iPhone tells me "Verbindung zum Netzwerk xxx fehlgeschlagen").
My phone provider is callmobile.
I am looking forward to any help and support.
iPhone 3G, iOS 4, no jailbrake
