How to change WiFi used to set up iPhone
When I bought my new iPhone 11, to set it up, I connected to the store's WiFI and logged in my iCloud. Since the WiFi there was slow and the backup restoration was taking forever, I decided to go home and restore my backup. Now that I'm at home though, my iPhone is still connected to the store WiFi and I can't change it to my home WiFi to continue the restoration. How do I do a factory reset and start from scratch so I can connect to my home WiFi?
iPhone SE, iOS 13
