6 Poor Wi-Fi connection? No problem!
With iOS 11 the Control Center has quick toggles for radios like Wi-Fi and Bluetooth. But they don’t actually turn off the service. Instead the radios are left on for features and integrations like AirDrop, Apple Pencil, and AirPods while disabling the connection to a Wi-Fi network and terminating connections to most paired Bluetooth devices.
Additionally, using geofencing and location data the phone determines when you’ve left the area and toggles the buttons back on automatically. It will also switch them back on after a certain period of time has passed. So if you can’t access a website on your current connection, just toggle off Wi-Fi. It will automatically turn back on when you leave the area or at a later time.
