Sometimes it might look like there’s no signal available on your cellular iPad when you’re pretty sure there should be, or maybe you’re having a hard time connecting to a Wi-Fi network.
Simply turning your iPad off and on again can bring it back to life and get a signal, but that takes time. Here’s a much quicker way to coax some signal out of the tablet.
Turn on Airplane Mode from Control Center and then turn it off again. This restarts the network circuitry and will usually locate that missing signal.
