How Do I Removed Stored WiFi Networks From My iPad?
You can force your iPad or iPhone to forget wireless networks. Go to the Settings app to Wi-Fi. Once the list of the available Wi-Fi networks appears, tap once on the blue arrow next to the network you do like to remove. You will be taken to the settings for the network. From there, you will see a button that says "Forget this Network". Select it and you will no longer have to worry about accidentally connecting to that network.
