Wifi scheduling restrictions

[Franchesca]

Recently my son bought a new phone so I'm using his old iPhone 8 now. There used to be a wifi scheduling restriction on his phone so I took it off but it still won't let me access the internet during the time his old restrictions were. In advanced settings it says there are no scheduling restrictions on any devices at the moment but this phone still doesn't have access to wifi during select periods of time. Please help!

Did you reset the phone to factory settings when you acquired it?

As a final step, if nothing else works, you can reset the router to factory settings as well, though you will need to rebuild any network changes you made.
