• If you're connected to a Wi-Fi network but you can’t get online, try to use your Wi-Fi network on other devices. If you can't get online using your other devices, there might be a service outage. Call your cable company or internet provider for help.
• Try connecting to a Wi-Fi network in a different location. If your device can connect, you need to get help with your Wi-Fi network. If your device can't connect to any Wi-Fi networks, contact Apple.
• Update your Wi-Fi router with the latest firmware and make sure that the router supports your Apple product. For more information, contact the router's manufacturer.
