For a year, I have used wifi in 6D to take photos (20 photos/week) .Suddenly wifi disappear on the camera, and will not "exist" any more. I try to activate it, but it is "wifi off". I have delee wifi-connections and done it from the start again, then the wifi is on for only one photo, and then the wifi is gone again. Do I need to replace something in the camera ????
