The first technique used in most errors that occur with the iPhone is to try to restart the device, this operation is completely harmless. This simple workaround sometimes works.


On your iPhone 12, press the volume up button + power button together until the power off slider appears.

Drag the slider, then wait 30 seconds for the device to turn off completely. Next press and hold the power button until you see the Apple logo appear to turn the iPhone on.

When the machine does not recognize the wifi, you can try choosing to forget the password and then reconnecting. This method can also be used when entering the correct WiFi password, but the device reports you entered incorrectly.

Go to Settings, go to WiFi. Tap on a network that you cannot connect to and select Forget this network, then tap to confirm Forgot.
Then go back to Settings> WiFi, select the network again, enter the password to connect to the network again to see if it’s successful.

Resetting the network settings clears cache, clears DHCP settings, and other network-related information. Hence the WiFi problems we encountered will likely be fixed.

If you have a VPN installed, this could be one of the main reasons affecting your device’s WiFi connection. Try disabling the VPN to see if it solves the problem by: Open Settings> General> VPN. Toggle the shortcut under Status to disconnect from the VPN you set up earlier.


Sometimes the problem is not with the iPhone but with the Router itself. Try restarting your Router, then connect your iPhone to the WiFi network again to see if the device is connected to the network stable.
Once turned off, you should wait 10 seconds before turning the router back on again to make sure that the power is completely discharged and the memory is cleared. This ensures that previous settings on the Router will be reset.

To turn off WiFi network service, go to Settings> Privacy> Location Services> System Services> Turn off Network & Wireless Connection.

The WiFi Assist feature on iOS allows the device to automatically use mobile data when the WiFi connection is poor. However, some users believe that turning this feature off and on again improves some WiFi connection errors.
To disable this feature, open Settings> Cellular> scroll to the bottom to turn WiFi Assist on and off again.

This is not an appreciated one however if the solutions above do not work, you can try it by going to Settings> WiFi> Ask for network connection and selecting Ask or Notifications.

If the methods above fail to fix the problem then the last solution we can try with that iPhone is to reset it. But first, back up important data to iCloud to avoid data loss.
Do this by going to Settings> General> Reset> Erase all content and settings.
