My iPad mini which I have had for a while seems to be having some issues. It won't connect to the app store or iTunes, and when I try to get on the internet(I have tried both Chrome and Safari) I am told that I can't because my connection is insecure. The device isn't jailbroken, so I'm assuming this isn't a virus. I have also tried resetting my network settings which didn't help.
Try resetting your router. Unplug it from the power source for about 30 seconds. Then plug it in again.
Reset your iPad as well by holding down on the sleep and home buttons at the same time until the Apple logo appears on the screen. It takes about 10-15 seconds. Ignore the red slider bar if it appears on the screen.
