I also have a 7 plus with weak WiFi. When I say weak, I don't really mean that it is slow, but the range is quite a bit less than my 6 plus was. I have noticed this while out in my shop. With my 6 plus, I can get WiFi signal really easy. Now with the 7 plus I only get about 10 feet through the door and my signal drops. Has apple or anybody addressed this issue yet?
