1. Be sure you're in range of your Wi-Fi router (access point).

 

2. Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your W-Fi setting is dimmed, follow these steps.

4. Restart your iOS device.

 

5. Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.

 

6. Tap  and Forget this Network.

 

7. 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.

 

8. Turn your Wi-Fi router off and on. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.

 

9. Update your device to the latest version of software.

 

10. Update your Wi-Fi router to the latest firmware. For AirPort Base Stations, install updates using the AirPort Utility.

          - previously connected Wi-Fi networks and passwords

          - recently used Bluetooth accessories

          - VPN and APN settings
