Yesterday, my ability to receive gmail,facebook,safari,etc. ceased to perform The wifi connections shows that it is connected but I cannot get through the internet . I use a Cisco router and it is working fine with another computer and also a printer. I contacted the internet provider and they show the ipad at the router but not out through the internet. Also, yesterday my wife eliminated some programs(games,etc) from the ipad. Anway, I am thinking I am missing some setting that is not turned on as everything seems to be working fine.

Any suggestions?
