I recently have been having problems with my iPhone not finding any wifi networks, even though I know they are there. My wife and I both have the same iphone, and her's will find wifi networks, but mine won't. I used to find them all the time, but now for some reason it can't find any. I have not done anything to the phone, and I can't figure out what is happening. Any help would be greatly appreciated!

    Try powering your iPhone off and on first followed by an iPhone reset if you haven't already done so.

    If no change, on your iPhone go to Settings > General > Reset and select Reset Network Settings. This will delete all wi-fi network settings from your iPhone for every wi-fi network you have connected your iPhone with.

    If no change after this, try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup. Wi-Fi network settings are included with your iPhone's backup so if there is a problem in this regard with your iPhone's backup, restoring from the backup will also restore the problem. If no change after this, more than likely your iPhone has a hardware problem - with the wireless card or with something else.

    If you are in the U.S., you can call AppleCare or make an appointment at an Apple store if there is one nearby.

    Thanks for the information. If I restore it as a new phone, will I lose everything?

    You're welcome.

    Yes - you will lose all data included with your iPhone's backup if you don't restore from the backup, but you won't lose any iTunes content on your iPhone or any photos transferred from your computer to your iPhone, which should remain on your computer. Photos and videos in your iPhone's Camera Roll are included with your iPhone's backup and will be lost also, but photos and video in your iPhone's Camera Roll should be imported by your computer as with any other digital camera. If you haven't already done so, import all photos and video in your Camera Roll before restoring as a new iPhone. Contacts are included with your iPhone's backup, but contacts are designed to be synced with a supported address book application on your computer. If you are syncing contacts with a supported application on your computer, your contacts will not be lost, nor will your calendar events be lost if you are syncing calendar events with a supported application on your computer.

    If no change after restoring as a new iPhone, more than likely your iPhone has a hardware problem. This won't prevent you from restoring from the existing/previous backup afterwards, or transferring the existing/previous backup to a new iPhone if your iPhone is exchanged under warranty.
