I have an iphone 4s iOs 9.3.5 and I cannot turn on wifi. I have completed a hard reset and reset the network and nothing has worked. When I go into setting the wifi is labeled off. When clicked the wifi button will not slide to the on position. Any other suggestions?

Try restoring the device to factory and without adding any additional content see if you can turn wi-fi on. If not, there really isn't much else you can do. See this support document for other troubleshooting steps. If Wi-Fi is grayed out or dim on your iPhone, iPad, or iPod touch - Apple Support
