Before visiting our store, we recommend trying to connect 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 us to get it fixed. A greyed out WiFi symbol on your iPhone might indicate that a component has failed on the main logic board. We will perform a diagnosis to confirm that this is actually the issue, and repair it if necessary. Express Service uses only the best quality parts available on the market to ensure that you leave the store with your iPhone ready to connect to Wi-Fi.
