If we are still having problems, it is time to actually start changing some settings. This mostly has to do with telling the iPad to forget what it knows about connecting to the Internet and giving the iPad a fresh start.
This first option is on the same screen we visited before when we were checking the settings and renewing the iPad's network lease. You can get back there by tapping the settings icon and choosing WiFi from the left-side menu.
Once you are on the WiFi Networks screen, you will want to get into the settings for your individual network by touching the blue button beside the network name. The button has a ">" symbol in the middle.
This will take us to a screen with settings for this individual network. To forget the network, tap "Forget this Network" at the top of the screen. You'll be asked to verify this choice. Choose "Forget" to verify it.
You can reconnect by choosing your network from the list. If you are connecting to a private network, you will need the password to reconnect.
