    Is it unable to connect to any wifi? Friends, families ect?
    If yes, then try restoring and set it up as new in iTunes.
    Note: You will lose all data in this process, so save what you can in external programs like Outlook, Photos ect.

    At the iPhone hacks section.
    I doubt a restore will fix a broken wifi chip but give it a shot if you want anyway.
    You will need to bring it to an iphone repair shop to replace the wifi module on the logic board.
