Use a Computer and Ethernet:

Start with attempting an update through use of a computer. But this time, user Ethernet.  Go Here: Making Use of a Computer for Updating an iOS Device - User Tip. On the computer, you would connect it through Ethernet, going directly into your router. For a Mac (or PC) that does not have Ethernet, this would be the adapter to use: Belkin USB-C to Gigabit Ethernet Adapter - Apple
