Typically, all helplines are closed for the night at apple.
I got an iPhone 12 today and am trying to finish the restore from backup started in store.
The guy told me to go home, connect to wifi and let it finish.
Every time I connect to my wifi it stays on for approx 3 seconds then goes back to 4g.
So far I have tried switching the iPhone off and on again. Switching router off and on again. Resetting network settings. Forgetting the router and refinding it an manually inputting the password.
Any thoughts? I am tearing my hair out with it.
