Any WiFi router that has MAC filter enabled may not accept the “Private” MAC address feature of the new feature added in iOS 14.0.1 to each WiFi profile saved. Turning off the private Mac Address on the specific WiFi profile may allow your device to connect.


Another issue is it connects fine but moments later it prompts for password on a saved profile. Turning off “wifi assist” in Cellular settings (absolute bottom of the list) will allow the device to remain connected on weaker range areas of this wifi profile.


I suspect the failing over to WiFi profile flip flopping is triggering a false positive on the algorithm that the wifi profile saved is incorrect and thus asks for a re-authentication.

In my point of view it is a bug. because it gives only "weak security" warning, seems connected to my home network, however does not work healthy. I needed to renew my wifi connection frequently. If Apple would announce that they don't support anymore these type of encryption that is OK, not a bug. I haven't seen any announcement regarding this issue, have you?

Lawrence, I'm still troubleshooting this with Apple Support. More time on the phone and repeating the same old steps (reset to factory and restore for the 4th time), which wasted a lot of time and solved nothing.


In the Developers Forum, there are discussions about Apple implementing DoH in iOS14 and the problems it caused with wifi. Symptoms sound very familiar. Any comment?

Just upgraded my mom from the iPhone 6 to the iPhone 12 and my dad from the iPhone SE to the iPhone 11and they instantly started complaining that there is no internet. They continuously have to disable then enable WiFi for it to work. They keep complaining and want to go back to their old phones. Whatever Apple did to “improve” WiFi like the weak security message or the private address screwed it up.

I have an Iphone XR, a week ago I have upgraded to ios 14.0.1. Frequently I am facing with wifi problems. Although wifi image shows that I am connected to wifi network applications give no internet connection error. Simultaneously I can reach to the same apps through the same network with my other devices.


Additionally when I turn off/on Wifi on my iphone it connects to the network, however does not show any network.
