Can anyone help me please?
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

    backup and new installation of iPhone.


    If this means you restored your iPhone with iTunes from your iPhone's backup, wi-fi network settings are included with your iPhone's backup. If there is a problem with your iPhone's backup in regards this data, restoring from the backup will also restore the problem.

    Any problem connecting your iPhone to any other wi-fi network besides your own?

    If no change after resetting network settings on your iPhone and/or after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, if you are unable to connect to any wi-fi network after restoring your iPhone with iTunes as a new iPhone, your iPhone has a hardware problem with the wireless card or with something else.

    Have you tried rebooting your router? Unplug it for about 15 seconds.

    Thank you for your quick answer. I have reset and restored my iPhone with iTunes, I tried once as back-up and now just tried to reset and restore as new iPhone. It still does not work.

    In addition, I have tried resetting the wi-fi network settings, which did not help either.

    I have not tried using the iPhone with another wi-fi network yet. However the iPhone still worked with wi-fi only a few days ago.

    Do you have any other suggestions which I could try?

    Hi, yes, I also tried to reboot the router, which I forgot to mention. But it still does not work.

    You're welcome.

    What you have been provided are your only options.

    If a hardware problem, hardware can fail at any time.

    You never go anywhere with your iPhone such as a coffee shop, restaurant, or any business that provides free internet access via wi-fi for their customers? If you are unable to connect your iPhone to any other wi-fi network besides your own after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, this will indicate your iPhone has a hardware problem with the wireless card or with something else.

    You are right, I should try to connect my iPhone to another wi-fi connection (at a restaurant or somewhere else) to see if it has a hardware problem. I will try and then get back on this issue.

    I have now tried to connect to another Wi-Fi with my iPhone, and it also does not work. What should I do now?

    Your iiPhone has a hardware problem. If purchased new in the last year, the iPhone includes a one year warranty. If no longer under warranty, Apple has an out of warranty repair price which pays for an exchange for the same model at a discounted price off what was the full retail sales price. The cost in the U.S. is $199 plus applicable sales tax.

    Thank you. I purchased it two years ago. I think it is quite early to already have a hardware problem, but it could be the case. I thought that the quality of an iPhone would be higher than lasting just two years and am very disappointed.

    You're welcome.

    I have an iPhone 3G used as an iPod Touch that I purchased in the summer of 2008 which still works fine. The most expensive and quality items in the world have a failure rate. It happens.
