Q: why won't my network download for WIFI

Howdy Caroline,

It sounds like you are trying to connect to your Wi-Fi network, or you are conencted but are unable to download the recent iOS 7.1.1 update. I would use this troubleshooting from the following article to help resolve or isolate the issue:

iOS: Troubleshooting Wi-Fi networks and connections

1. Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your Wi-Fi setting is dimmed, follow these steps.
2. Restart your iOS device.
3. Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
4. Tap and Forget this Network.
5. Try to connect to your desired Wi-Fi network.
   Note: You may need to enter your Wi-Fi password again if your network requires one.
6. Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
7. Update your device to the latest version of software.
8. Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.

And

 

1. Make sure you're entering your Wi-Fi password correctly. Passwords may be case sensitive and may contain numbers or special characters.
2. Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
   • previously connected Wi-Fi networks and passwords
   • recently used Bluetooth accessories
   • VPN and APN settings

If this is not the case, would you mind clarifying what symptoms you are seeing when trying to update your phone?

Thank you for using Apple Support Communities.

Take care,
