Just go into Settings and disable it as usual.

Or just place it in Airplane Mode and enable Wifi or Bluetooth selectively. At least that's what I do in iOS 10. I hope it's still possible in 11.

I think these latest sets of wifi flaws are interesting if it turns out they are exploitable by merely being in radio range of an attacker even without joining a malicious network or requiring user interaction. That could quickly become a fast and wormable attack. You could probably flood across an entire city jumping from chip to chip in no time.

I can.. it makes those buttons much more useful for the common case. e.g. this wifi network isn't working, disconnect.. and not forget to reconnect later. I did that often.

And also being hassled about location services not working, etc.

You can still actually disable both through the settings up, just not with the quick access.

I really don’t understand why people keep those two off. If you’re not using them they use very little battery at this point; it’s not like it was 10 years ago. Since Apple keeps detailed usage statistics (from the people who opt in) my guess is they know how common such a behavior is and it’s obviously low enough they don’t think this change is a problem. I agree with some of the other comments I’ve seen that this p…

I keep it off because as I ride a train it's connecting to every station wifi and losing it just as quick, completely breaking connectivity.

Is it really that difficult to use? C'mon... Just force touch it instead of regular touching and you get the same control as before.

Turn off "ask to join" and it will only connect to known networks.

The station wifi is known though, so when I have a long wait for a train at a station I'm not burning data on YouTube

Apple's explanation of why they did this. https://support.apple.com/en-us/HT208086

Thanks, their description is interesting. It’s not quite as bad as I thought.
