Resolution

Many Wi-Fi issues can be resolved by doing the following:

Basic troubleshooting

• Tap Settings > Wi-Fi and turn Wi-Fi off and then on again.
• Verify that you are in range of your Wi-Fi router or base station.
• Confirm that your Wi-Fi router and Cable/DSL modem are connected to power and turned on.
• Check whether other devices (portable computers, for example) are able to connect to the Wi-Fi network and access the Internet.
• Update your Wi-Fi router to the latest firmware.

  For AirPort Base Stations, refer to this article for information about firmware updates. For third-party Wi-Fi routers, check the manufacturer's website for details on updating your firmware.

• Restart your iOS device

  Hold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.

Hope this helps,

Mario
