How to Deal with WiFi that Won’t Connect on iPhone 12

A WiFi connection error can be due to server maintenance from your Internet service provider’s end. If this is the first time that you have encountered the issue and it is not only affecting your iPhone 12, then contact them first to verify the status of their internet service. 

If you have found out that there is no problem on their end and your iPhone 12 still won’t connect to your WiFi, then it is time to follow the procedures that I have mapped out below. 

First Solution: Restart your Modem/Router

Internet glitch could happen if your internet modem/router has been running for a certain period and has not been turned off. It is important to reset your internet equipment once in a while as it will allow a system refresh and may eliminate internet connection problems that may have been hindering your iPhone 12 to connect to WiFi.

Second Solution: Reset your iPhone 12

Performing a simple reset procedure might do wonders as it is proven to deal with many issues surfacing on smartphones. If the WiFi connectivity problem is caused by a minor glitch, then this could be the answer that we are looking for.

Third Solution: Check for iOS update on your iPhone 12

Fourth Solution: Reset Network Settings on your iPhone 12

A reset network settings procedure allows you to erase all manually configured network settings including WiFi networks on your iPhone and revert them to their default values and options. That means if the WiFi won’t connect problem on your iPhone 12 is caused by conflicts with the saved WiFi networks on your phone, it should be cured right after following the procedures below.

Since WiFi networks will be deleted on your phone, you will need to connect to the WiFi network like the first time. Make sure that you enter the correct password and check if the iPhone 12 won’t connect to WiFi up to this point.

If your iPhone 12 still won’t connect to your WiFi, then it may have been experiencing a major glitch that needs a stronger solution. Factory reset will delete all contents on your phone, including stagnant bugs that may have been hindering the WiFi functionality on the device. Make sure to create a backup via iTunes or iCloud prior doing a factory reset. 

To create a backup via iTunes: 

  1. Prepare a Mac or Windows computer with the latest iTunes installed. Also ensure that your computer runs on the latest operating system that is compatible with your iPhone.
  2. Connect your device to the computer using the Apple-supplied USB/lightning cable.
