So I upgraded my iPhone 6 to iOS 10, but I have this issue whereby it says its connected to WiFi but its not. If I go into the settings menu for WiFi, which lists all the networks around me. I click on mine and it 'ticks' it to indicate its connected, but I still have the 4G symbol at the top of the phone and apps that require WiFi, won't work as they say I am using mobile data. I have done - - Reset of Network Settings. - Restarted Phone - Toggled between airplane mode - Toggled WiFi on and off - 'forgot' this network I have another iPhone 6s and an iPad 4 both running iOS10 and the do not have this WiFi issue, so I don't think my router is the issue (Though I did reboot it anyway). This was working prior to iOS 10. Any ideas guys?
