Failure to reconnect to networks on iOS

Solution 1:

Things to try... is the same behavior observed if you:

• borrow an iDevice (running iOS 14) from someone else and connect it to your network
• temporarily disable MAC filtering and/or the hidden attribute of your wireless network

(I’ve made the assumption that you’ve already re-booted both your iOS device and the Airport Extreme, and that they both have the most current software.)

As a last resort (that won’t cause you to lose any data, but that will delete any saved WiFi passwords not saved to iCloud - maybe turn off iCloud first just to be safe):

• Use the “Reset Network Settings” option under Settings > General > Reset

While not the issue in your case, others may encounter a similar issue with the ‘private address’ feature in iOS 14, on a network has MAC filtering enabled.

1. When connected to your network, does “Privacy Warning” appear under the network name on the Wi-Fi settings?
2. If not, click the info circle to the right of the network name, then toggle off the “Private Address” option, which by default in iOS 14 assigns a new MAC address to your device on a regular basis (each time? every day?)
