Q: Wireless Sync Problem.

My iPad Mini and iTunes 11.2 are both setup to wirelessly sync. The sync starts just fine, telling me that iTunes is 'preparing to sync', syncing email accounts, and then the sync stops, showing the message "The iPad cannot be synced. An unknown error occurred (-50)"

 

Any ideas anyone? Thanks!

iPad, iOS 7.1.1

    Howdy lightworks56,

     

    It sounds like you are getting error code 50 when trying to sync your iPad to your computer. I would use the troubleshooting from the following article named:

     

    iTunes 10.5 and later: Troubleshooting iTunes Wi-Fi syncing

    http://support.apple.com/kb/ts4062

     

    Start with these steps:

    Quit and reopen iTunes and restart your iOS device

    Quit and reopen iTunes on your computer. Then, restart your iOS device.

    Restart your network router

    Restart your home network router using the manufacturer's instructions. You may need to disconnect the power cord for 30 seconds or more.

    Note: During this time, Internet services, such as a VoIP-based phone, won't work, and you may need to reset additional network devices.

    Check your network connection

    • Make sure that your Wi-Fi network has an active Internet connection.
    • Make sure that you connect your iOS devices and computer to the same network over Wi-Fi.
    • Check for network configuration changes that may interfere with syncing:
      • VPN configurations
      • Extending the Wi-Fi network through multiple wireless access points or routers
      • Guest networks or other security configurations that limit access between devices
      • Routers that configure different networks for different frequencies such as 2.4 GHz and 5.0 GHz
      • Connecting the computer over Ethernet
    • Wake up your computer and open iTunes. If your computer is asleep or iTunes isn't open, the device may not sync.
    • Update your router. If you're using an AirPort or AirPort Time Capsule, you can learn more about firmware updates. If you're using a router from another manufacturer, contact the manufacturer to ask about available updates.

     

    There are additional steps to use after these if needed in the article.

     

    Thank you for using Apple Support Communities.

    All the best,

    Sterling

    Thanks for that. I've been through this process more than once, but with no success.

     

    One thing I have discovered, when the sync starts ... then stops, is that my iPad tells me that the sync will happen the next time my computer is "available", so I can only assume that the iPad and the computer are 'losing touch' with each other, after the sync begins.

     

    So I think this could be a firewall configuration problem. Since I use Norton 360 rather than the Win 7's firewall, I'm going to investigate that. Otherwise, it's probably at the router's end.

     

    If I have any more news, I'll post back later.

     

    Wish me luck.

    Hello lightworks56,

     

    I'm  Harry from Norton Support team. Did you try disabling the Norton  firewall temporarily? Also, check if the iPhone/iPad device is showing  up in the Network Security Map of Norton & set to Full trust. This  can help you to find if Norton is causing the connectivity problem.

     

    Thanks!

    Harry

    Hi Harry, and thanks very much for picking up on this thread.

     

    I've done all you suggested, and have to say that I don't think it's Norton 360 that's causing my problem. By a process of elimination it seems to be my router (which is an old Netgear DG834G).

     

    I've been having some reliability issues with this router for a few months now, and although it's been brilliant over many years, I think it now needs to be gratefully retired.

     

    Many thanks for your help and input Harry. It's much appreciated.

     

    Simon.
