iPhone 6 Wi-Fi doesn't Fly

<p>Since upgarding to iOS 9.3.5 my iPhone 6 has not been able to connect to my Wi-Fi network (Fibre) at my place of residence. My iPad, Apple TV, iPhone 5C have no connectivity issues.</p> <p> </p> <p>As a last resort I gave my phone in for diagnostics at the Apple Store at Sandton City. After a week I received feedback that there is no fault that they can determine.</p> <p> </p> <p>So they shipped the device bak to the store. (Oh, they also did not have the pin to remove the sim card inserter).</p> <p> </p> <p>Essentially they are saying there is nothing they can do to rectify the situation. I am left with a smart device that isn't able to be smart without an internent connection.</p> <p> </p> <p>The service left alot to be desired.</p>
