As always worked. But now, when I am in settings, it shows me connected to my home wifi with check mark, but never connects. Home wifi still works with laptop and other iPad.
I'm assuming that the settings on the offending iPad and those in your modem have not been changed? If not and if not already tried, then for starters, I would suggest restarting or resetting (the latter if restart does not work) - Directions HERE - your iPad; these simple steps often solve many pesky problems. If not successful, try to power recycle your modem and Wi-Fi router despite Wi-Fi working on your other devices - never know.
If none of these suggestions help, please post back - good luck!
When my Wi-Fi laptop in the den stops connecting to the internet, I just walk into the other room & power recycle my modem and router - usually brings it back into action 90% of the time - otherwise, probably an issue w/ my ISP (Road Runner for me) - glad that your up & running again - Dave
