A week ago we started to have to manually connect to Wifi every time we turned on our iPad. That is not a good thing.
iPad should find known network routers automatically. Well something was gumming up the Wifi works on our iPad.
After much searching and anguish, we corrected the issue by a simple reset of our network settings.
Do this. Go to and select Settings: General: Reset: Reset Network Settings. This will reset all your network settings to factory default, including passwords, VPN, and APN settings.
And once again your iPad will connect on its own to your known Wifi routers.
But warning -- do not reset your home screen layout if you have spent time organizing and grouping all of your app icons on different screens. That selection will alphabetize your apps icons.
Always exercise care when choosing a reset option on any device.
