Professor-Ken Said:
"iPhone 12 randomly has no internet connection. It works and then it doesn't. All other wifi devices in the house work fine. Several soft resets and network reset did nothing. A half hour later while trying to schedule an apple help desk appt, it started working again. Did not make appt, hoping to hear a resolution."
