The App Store allows you to download music, games and apps to your iPad through a wireless Internet signal produced by your network router. If you can access the Internet through a browser on your iPad, but you can’t connect to the App Store, your router's security settings are causing a connectivity issue. Log in to your router using a networked computer to change these settings and allow your iPad to connect to the App Store.
Some routers have built-in firewall capabilities made to protect computers and attached devices from attacks and malware from the Internet. However, this feature also occasionally blocks software and applications you want to use, such as the App Store. Opening up required ports on your router allows data to pass through from the App Store to your iPad. If this does not fix the issue, you can also attempt to factory reset your router.
Logging in to the Router
To open up a port on your router, log into the router using an administrator account. Type the router's Internet protocol address in the address bar of your browser on a computer or laptop connected to the router to launch the router login screen. The router prompts you for the administrator username and password before you can log in to view the router’s configuration. If you don’t know the IP address or administrator information, each router has default setting information available in the router’s user manual and documentation.
Opening Router Ports
Router configuration dashboards vary, but most allow you to open ports based on port numbers that software and applications need to use. Navigate to the “Advanced” or “Port Forwarding” section of the dashboard. Ensure that the transmission control protocol for both port numbers 80 and 443 are open. The App Store uses these two TCP ports to transfer data to and from your iPad, which allows you to connect to the app and download content. Save the settings and allow the router to reboot. If the firewall settings were the issue, you should now be able to connect to the App Store on your iPad.
If you can’t log in to your router or if the router’s configuration has been changed and port forwarding doesn’t work properly, reset the router. This allows you to roll the router configuration back to factory defaults and reset any specified configuration that may be preventing communication with the App Store. However, this also erases any custom settings you've set on the router and requires you to reconfigure the router from default to get the settings back. The reset button is usually a very small button located inside a hole on the back or side of the router. Insert the end of a pencil or a paper clip into the hole to press the button. The lights on the front of the router will flash, indicating the reset is complete.
