Q: My network is fine, iPad can't connect to internet via any router, even when other computers work fine.

Hi Jenroses,

I would suggest backing up your iPad and updating it to the latest iOS, which is iOS 6.1.4

iOS: Troubleshooting Wi-Fi networks and connections

1. Be sure that you are in range of your Wi-Fi router (access point).
2. Tap Settings > Wi-Fi and turn Wi-Fi off and then on again.
   • If unable to do so, see this article.
3. Confirm that your Wi-Fi router and Cable or DSL modem are connected to power, turned on, and indicate that they are connected to the Internet.
   • If not, refer to your network administrator or ISP for assistance.
4. Restart your iOS device.
5. Tap Settings > Wi-Fi and locate the Wi-Fi network to which you are connected. Then tap the blue dot and choose Forget this Network. Try to connect to your desired Wi-Fi network again.
   • Note: You will need to enter your Wi-Fi password again if your desired network requires one.
6. Turn your Wi-Fi router off and then on again². If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
7. Update your device to the latest version of software.
8. Update your Wi-Fi router to the latest firmware².
