This question already has an answer here:
In iOS 11 when we disable the Wi-Fi in the control center it doesn't actually disable the radio. According to Apple, the device is disconnected from Wi-Fi and auto-join is disabled until
- You turn on Wi-Fi in Control Center.
- You connect to a Wi-Fi network in Settings > Wi-Fi.
- You walk or drive to a new location.
- It's 5 AM local time.
- You restart your device.
When I disable Wi-Fi (or BT) I really want it off. Is it possible via some setting or application to get the old behavior back?
