Before we start tinkering with some of the other settings, let's reset the iPad. This basic troubleshooting step can cure all types of problems and should always be done before you actually start changing settings. Resetting or restarting the iPad is simple and only takes a few moments to complete.
To reset the iPad, hold the Sleep/Wake button at the top of the iPad down for several seconds until a bar appears on the screen beckoning you to "slide to power off".
Once you slide the bar, the iPad will display a circle of dashes before finally shutting down completely, which will leave you with a blank screen. Wait a few seconds and then hold down the Sleep/Wake button again to start the iPad back up.
The Apple logo will appear in the middle of the screen and the iPad will reboot completely a few seconds later. You can test out the WiFi connection once the icons reappear.
