Q: I just downloaded the new iOS 8 on my new Silver iPad Air 2 and it won't let me log on to game centre Help!?

Hello MicaelaD1,

Thanks for using Apple Support Communities.

To troubleshoot signing in to Game Center on your iPad please follow the steps in the article linked to below.

If you can't sign in to Game Center or stay connected, follow these steps:

1. Make sure that you're connected to the Internet.
2. If you can't create an account or sign in to Game Center from within a game, try to create an account or sign in using the Game Center app.
3. Sign out of Game Center, then sign back in. If you can't sign in to Game Center with an Apple ID, reset your password or use another email address. To manage your Apple ID, go to My Apple ID.
4. If you're using a Wi-Fi connection, make sure that your Wi-Fi router is configured for Game Center.
5. If you can't sign in on a Mac, continue with the steps to resolve sign in issues.
