In order for TouchCopy to find your iPhone, iPod Touch or iPad on a Wifi connection the following conditions need to be satisfied...
If, having followed these instructions, you are still unable to connect to your device over Wi-Fi you can still connect using a USB cable.
Note that connecting your device to TouchCopy over Wifi will be slower than connecting through a USB cable. So, if you have lots of music and photo to copy over using TouchCopy, we recommend connecting with a USB cable.
If the iPhone, iPad or iPod Touch has not previously been connected with a USB cable to the computer you are running TouchCopy on - TouchCopy will not find the device on a WiFi network. In this case, you will need to connect your iOS device to your computer using a USB cable.
Connect your device to your computer.
If your device has a passcode on the lock screen, enter the passcode to access your devices home screen.
For devices using iOS7 or higher, tap Trust on your device to trust your computer. If you choose not to trust the connected computer, you can charge your device, but the connected computer won't be able to access any content on your device.
iTunes or TouchCopy not finding your device when connected with USB? Troubleshooting an iPhone USB connection >
In order for TouchCopy to find your device on a WiFi network - you need to set the device up for WiFi Syncing. This is done with iTunes.
Connect your device to your computer using the USB cable as described above.
Start iTunes.
Click on the device icon in iTunes.
Scroll down the Device Summary view until you reach the "Options" section. Here you will see the checkbox "Sync this iPhone over Wi-fi". Make sure that this checkbox is checked. Then click the "Done" button to apply these settings.
Now, when you open iTunes and your iPhone/iPod/iPad is unlocked and on the same WiFi network, the device will appear in iTunes!
This also allows you to do the same in TouchCopy. Simply open TouchCopy, and unlock your device which is on the same WiFi network as the computer. Your device will show up in TouchCopy, without being connected with a cable!

1. Open Control Panel from your Start menu.
2. Choose "Network and Internet", then "Network and Sharing Centre".
3. Click "Change advanced sharing settings".
