Why can't iphone download software from appstore with its own wifi?

If you have been prompted that you can't download the application, you can try to change the DNS address of the wireless Wifi network to improve the connection effect between the mobile phone and the Apple application download server.

When downloading an application on a mobile phone, the current network connection speed is unstable, which leads to the situation that the application cannot be downloaded. Usually, you can click the Retry button to try again. It is recommended to click the information on the right side of wifi to enter the wifi settings and change the DNS inside.

1. Open the Settings application on your phone. Click the WLAN column in the settings list.

2. In the WLAN list, click the exclamation mark icon to the right of the currently connected wireless network.

3. Then, in the network parameters interface of the wireless network, click the DNS column. Delete all original DNS addresses and enter a new 8.8.8.8 address or change it to114.114.14.14.65438.

Then click the application that can't be downloaded, and then try downloading again. If it still doesn't work, you can close it and then open it again. Press and hold the power button on the top of the iPhone, and then slide the slider to turn it off when the power off option appears.

If it still doesn't work, you can call Apple Customer Service at 400-666-8800.
