IPhone 12 Pro will no longer connect to wifi
iPhone 12 stopped connecting to home wifi
Question marked as
Is your iPhone 12 Pro connecting to you home Wi-Fi Network and then not able to connect to the internet OR it just cannot connect to your Wi-Fi Network even with the right password? Which iOS version are you using? I am going to assume that you are using iOS version 15.0.1
You can try the following, open Settings ➔ General ➔ Transfer or Reset iPhone ➔ Reset ➔ Reset Network Settings. Note that when you do this, then you will have enter your Wi-Fi password(s) again.
If the above does not work, then you can try and reboot your Wi-Fi Network's Router at your house. Simply unplug it for 40 seconds and then plug it back again. Allow the reboot process to complete for 5 minutes or so and then try connecting your iPhone 12 to it.
