So if your apple iphone 6 is having problems connecting to wifi it is a common problem so don’t worry just yet. First thing you want to try and do is restart your router and iphone. If that does nothing go into the settings on your iphone 6 and scroll down to reset. Next in the reset section click reset network settings. Don’t worry this will not delete anything on your iphone 6. Click this option and accept. Once you do this your iphone 6 will restart and it will take about 30 to 40 seconds. If your still having problems after this you can try resetting your entire phone as a last resort.
