ipad wifi not recognized

[Boca]

Ipad 2. Airport express. I am using a mac on the wifi system. The ipad has worked on the same wifi in my apt. BUT now it recognizes the wifi, shows full bars in the signal but will not connect.
Took it to local apple store and in store it connected no problem. So, brought it home and it worked fine for about a week....now it will not connect.

The macbook works fine and also a laptop we have. But the ipad and now our iphones will not work on the system.

Suggestions please? Thanks and have a great day.

Go to Settings>General>Reset>Reset Network Settings. This will cause your iPad to forget every network it has ever connected to. If you've connected to a ton of Wi-fi places and don't want to reenter keys, don't do this.

EDIT* Never mind. It looks like someone suggested it to you in another thread.
