Gina's iPhone 6 is having problems connecting to the internet via Wi-Fi. Leo says to make sure she can't get on anyone else's Wi-Fi. If that's not the case, then there is clearly something wrong with the phone or its Wi-Fi settings. It's possible that the settings are preventing it from connecting, but it's also likely the hardware has failed. The only real people who can solve a hardware issue are Geniuses at the Apple Store. Gina should set up an appointment and have the Genius take a look at it.
