Please try renewing your DHCP lease. This can be done by following these steps:
1. Launch the Settings app and navigate to Wi-Fi;
2. On the right side of your wireless network, tap on the i button to bring up the settings for your Wi-Fi network;
3. Tap on the blue Renew Lease button at the bottom of the settings pane to reset your device’s IP address and to refresh your connection;
4. Reboot the phone after that.
希望幫到大家!!
