I have a Microsoft Lumia 640XL, and I am unable to turn on/off my WiFi. The Settings menu is showing that it's turned on, but when I click on the WiFi option it shows as off. I am unable to turn it on and it's not connecting it to any WiFi available nearby and not searching any as well.
I have done a soft reset, a hard reset and install even new OS and still is not working. What can I do?
